UFO

Unidentified flying object (commonly abbreviated as UFO or U.F.O.) is the popular term for any aerial phenomenon whose cause cannot be easily or immediately determined.^[1] Both military and civilian research show that a significant majority of UFO sightings have been identified after further investigation, either explicitly or indirectly through the presence of clear and simple explanatory factors (see Occam's Razor).^[2] The United States Air Force, which coined the term in 1952, initially defined UFOs as those objects that remain unidentified after scrutiny by expert investigators,^[3] though the term UFO is often used more generally to describe any sighting unidentifiable to the reporting observer(s). Popular culture frequently takes the term UFO as a synonym for alien spacecraft. Cults have become associated with UFOs, and mythology and folklore have evolved around the phenomenon.^[4] Some investigators now prefer to use the broader term unidentified aerial phenomenon (or UAP), to avoid the confusion and speculative associations that have become attached to UFO.^[5]

Studies have established that only a small percentage of reported UFOs are actual hoaxes,^[6] while the majority are observations of some real but conventional object—most commonly aircraft, balloons, or astronomical objects such as meteors or bright planets—that have been misidentified by the observer as anomalies. A small percentage of reported sightings (usually 5 %–20 %) are classified as unidentified flying objects in the strictest sense (see below for some studies).

Certain scientists have argued that all UFO sightings, in the strictest sense, are misidentifications of prosaic natural phenomena^[7] and historically, there was debate among some scientists about whether scientific investigation was warranted given available empirical data.^{[8][9][10][11][12]} Very little peer-reviewed literature has been published in which scientists have proposed, studied or supported non-prosaic explanations for UFOs.

UFO reports became frequent after the first widely publicized US sighting – reported by private pilot Kenneth Arnold in 1947 – that gave rise to the popular terms "flying saucer" and "flying disc". Since then, millions of people have reported that they have seen UFOs.^[13]

History

Unexplained aerial observations have been reported throughout history. Some were undoubtedly astronomical in nature: comets, bright meteors, one or more of the five planets that can be seen with the naked eye, planetary conjunctions, or atmospheric optical phenomena such as parhelia and lenticular clouds. An example is Halley's Comet, which was recorded first by Chinese astronomers in 240 B.C. and possibly as early as 467 B.C.

Other historical reports seem to defy prosaic explanation, but assessing such accounts is difficult. Whatever their actual cause, such sightings throughout history were often treated as supernatural portents, angels, or other religious omens. Some objects in medieval paintings can seem strikingly similar to UFO reports.^[14] Art historians explain those objects as religious symbols, often represented in many other paintings of Middle-Age and Renaissance.^[15]

Shen Kuo (1031–1095), a Song Chinese government scholar-official and prolific polymath inventor and scholar, wrote a vivid passage in his Dream Pool Essays (1088) about an unidentified flying object. He recorded the testimony of eyewitnesses in 11th-century Anhui and Jiangsu (especially in the city of Yangzhou), who stated that a flying object with opening doors would shine a blinding light from its interior (from an object shaped like a pearl) that would cast shadows from trees for ten miles in radius, and was able to take off at tremendous speeds.^[16]

• On January 25, 1878, The Denison Daily News wrote that local farmer John Martin had reported seeing a large, dark, circular flying object resembling a balloon flying "at wonderful speed." Martin also said it appeared to be about the size of a saucer, the first known use of the word "saucer" in association with a UFO.^[17]
• On February 28, 1904, there was a sighting by three crew members on the USS Supply 300 miles west of San Francisco, reported by Lt. Frank Schofield, later to become Commander-in-Chief of the Pacific Battle Fleet. Schofield wrote of three bright red egg-shaped and circular objects flying in echelon formation that approached beneath the cloud layer, then changed course and "soared" above the clouds, departing directly away from the earth after two to three minutes. The largest had an apparent size of about six suns. ^[18]
• 1916 and 1926: The three oldest known pilot UFO sightings, of 1305 cataloged by NARCAP. On January 31, 1916, a UK pilot near Rochford reported a row of lights, like lighted windows on a railway carriage, that rose and disappeared. In January 1926, a pilot reported six "flying manhole covers" between Wichita, Kansas and Colorado Springs, Colorado. In late September 1926, an airmail pilot over Nevada was forced to land by a huge, wingless cylindrical object. ^[19]
• On August 5, 1926, while traveling in the Humboldt Mountains of Tibet's Kokonor region, Nicholas Roerich reported that members of his expedition saw "something big and shiny reflecting the sun, like a huge oval moving at great speed. Crossing our camp the thing changed in its direction from south to southwest. And we saw how it disappeared in the intense blue sky. We even had time to take our field glasses and saw quite distinctly an oval form with shiny surface, one side of which was brilliant from the sun.” ^[20] Another description by Roerich was, "...A shiny body flying from north to south. Field glasses are at hand. It is a huge body. One side glows in the sun. It is oval in shape. Then it somehow turns in another direction and disappears in the southwest." ^[21]
• In the Pacific and European theatres during World War II, "Foo-fighters" (metallic spheres, balls of light and other shapes that followed aircraft) were reported and on occasion photographed by Allied and Axis pilots. Some proposed Allied explanations at the time included St. Elmo's Fire, the planet Venus, hallucinations from oxygen deprivation, or German secret weapon. ^[22][23]
• On February 25, 1942, U.S. Army observers reported unidentified aircraft both visually and on radar over the Los Angeles, California region. Antiaircraft artillery was fired at what was presumed to be Japanese planes. No readily apparent explanation was offered, though some officials dismissed the reports of aircraft as being triggered by anxieties over expected Japanese air attacks on California. However, Army Chief of Staff Gen. George C. Marshall and Secretary of War Henry Stimson insisted real aircraft were involved. The incident later became known as the Battle of Los Angeles, or the West coast air raid.
• In 1946, there were over 2000 reports, collected primarily by the Swedish military, of unidentified aerial objects in the Scandinavian nations, along with isolated reports from France, Portugal, Italy and Greece, then referred to as "Russian hail", and later as "ghost rockets", because it was thought that these mysterious objects were possibly Russian tests of captured German V1 or V2 rockets. Although most were thought to be natural phenomena like meteors, over 200 were tracked on radar and deemed to be "real physical objects" by the Swedish military. In a 1948 top secret document, the Swedish military told the USAF Europe in 1948 that some of their investigators believed them to be extraterrestrial in origin.

The Kenneth Arnold sightings

Main article: Kenneth Arnold#June 24, 1947 UFO sighting

This shows the report Kenneth Arnold filed in 1947 about his UFO sighting.

The post World War II UFO phase in the United States began with a famous sighting by American businessman Kenneth Arnold on June 24, 1947 while flying his private plane near Mount Rainier, Washington. He reported seeing nine brilliantly bright objects flying across the face of Rainier.

This shows Kenneth Arnold holding a picture of a drawing of the crescent shaped UFO he saw in 1947.

Although there were other 1947 U.S. sightings of similar objects that preceded this, it was Arnold's sighting that first received significant media attention and captured the public's imagination. Arnold described what he saw as being "flat like a pie pan", "shaped like saucers and were so thin I could barely see them… ", "half-moon shaped, oval in front and convex in the rear. … they looked like a big flat disk" (see Arnold's drawing at right), and flew "like a saucer would if you skipped it across the water". (One of the objects, however, he would describe later as crescent-shaped, as shown in illustration at left.) Arnold’s descriptions were widely reported and within a few days gave rise to the terms flying saucer and flying disk.^[24] Arnold’s sighting was followed in the next few weeks by hundreds of other reported sightings, mostly in the U.S., but in other countries as well.

After reports of the Arnold sighting hit the media, other cases began to be reported in increasing numbers. In one instance a United Airlines crew sighting of nine more disc-like objects over Idaho on the evening of July 4. At the time, this sighting was even more widely reported than Arnold’s and lent considerable credence to Arnold’s report.^[25]

American UFO researcher Ted Bloecher, in his comprehensive review of newspaper reports (including cases that preceded Arnold's), found a sudden surge upwards in sightings on July 4, peaking on July 6–8. Bloecher noted that for the next few days most American newspapers were filled with front-page stories of the new "flying saucers" or "flying discs". Reports began to rapidly tail off after July 8,^[26] when officials began issuing press statements on the Roswell UFO incident, in which they explained debris found on the ground by a rancher as being that of a weather balloon.^[27]

Over several years in the 1960s, Bloecher (aided by physicist James E. McDonald) discovered 853 flying disc sightings that year from 140 newspapers from Canada, Washington D.C, and every U.S. state except Montana.^[28]

Investigations

UFOs have been subject to investigations over the years that vary widely in scope and scientific rigor. Governments or independent academics in the United States, Canada, the United Kingdom, France, Belgium, Sweden, Brazil, Chile, Uruguay, Mexico, Spain, and the Soviet Union are known to have investigated UFO reports at various times.

Among the best known government studies are the ghost rockets investigation by the Swedish military (1946-1947), Project Blue Book, previously Project Sign and Project Grudge, conducted by the United States Air Force from 1947 until 1969, the secret U.S. Army/Air Force Project Twinkle investigation into green fireballs (1948–1951), the secret USAF Project Blue Book Special Report #14 by the Battelle Memorial Institute, and Brazilian Air Force Operation Saucer (1977). France has had on ongoing investigation (GEPAN/SEPRA/GEIPAN) within its space agency CNES since 1977, as has Uruguay since 1989.

A public research effort conducted by the Condon Committee for the USAF, which arrived at a negative conclusion in 1968, marked the end of the US government's official investigation of UFOs, though documents indicate various government intelligence agencies continue unofficially to investigate or monitor the situation.^[29]

Jacques Vallée, a scientist and prominent UFO researcher, has argued that most UFO research is scientifically deficient, including many government studies such as Project Blue Book, and that mythology and cultism are frequently associated with the phenomenon. Vallée states that self-styled scientists often fill the vacuum left by the lack of attention paid to the UFO phenomenon by official science, but also notes that several hundred professional scientists continue to study UFOs in private, what he terms the "invisible college". He also argues that much could be learned from rigorous scientific study, but that little such work has been done. ^[30]

There has been little mainstream scientific study of UFOs, and the topic has received little serious attention or support in mainstream scientific literature. Official studies ended in the U.S. in December 1969, subsequent to the statement by Edward Condon that the study of UFOs probably could not be justified in the expectation that science would be advanced.^[10]The Condon report and these conclusions were endorsed by the National Academy of Scientists, of which Condon was a member. However, a scientific review by the UFO subcommittee of the AIAA disagreed with Condon's conclusion, noting that at least 30% of the cases studied remained unexplained, and that scientific benefit might be gained by continued study.

It has been claimed that all UFO cases are anecdotal^[31] and that all can be explained as prosaic natural phenomena. On the other hand, it has been argued that there is limited awareness among scientists of observational data, other than what is reported in the popular press.^[32][33]

Controversy has surrounded the Condon report, both before and after it was released. It has been claimed that the report was "harshly criticized by numerous scientists, particularly at the powerful AIAA … [who] recommended moderate, but continuous scientific work on UFOs".^[10]. In an address made to the AAAS, James E. McDonald stated that he believed science had failed to mount adequate studies of the problem, criticizing the Condon report and prior studies by the US Air Force for being scientifically deficient. He also questioned the basis for Condon's conclusions^[34] and argued that the reports of UFOs have been "laughed out of scientific court."^[9] Dr. J. Allen Hynek, an astronomer whose position as USAF consultant from 1948 made him perhaps the most knowledgable scientist connected with the subject, sharply criticized the report of the Condon Committee and later wrote two nontechnical books that set forth the case for investigating seemingly baffling UFO reports.

No official government investigation has ever concluded that UFOs are indisputably real, physical objects, extraterrestrial in origin, or of concern to national defense. These same negative conclusions have been found in studies that were highly classified for many years such as the UK's Flying Saucer Working Party, Project Condign, the US CIA-sponsored Robertson Panel, the US military investigation into the green fireballs from 1948-1951, and the Battelle Memorial Institute study for the USAF from 1952-1955 (Project Blue Book Special Report #14).

However, the initially classified USAF Regulation 200-2, first issued in 1953 after the Robertson Panel, which first defined UFOs and how information was to be collected, stated explicitly that the two reasons for studying the unexplained cases was for national security reasons and for possible technical aspects involved, implying physical reality, but without opinion as to origins. (For example, such information would also be considered important if UFOs had a foreign or domestic origin.) The first two known classified USAF studies in 1947 also concluded real physical aircraft were involved, but gave no opinion as to origins. (See American investigations immediately below) These early studies led to the creation of the USAF's Project Sign at the end of 1947, the first semi-public USAF study.

Project Sign in 1948 wrote a highly classified opinion (see Estimate of the Situation) that the best UFO reports probably had an extraterrestrial explanation, as did the the private but high-level French COMETA study of 1999. A top secret Swedish military opinion given to the USAF in 1948 stated that some of their analysts believed the 1946 ghost rockets and later flying saucers had extraterrestrial origins. (see Ghost rockets for document). In 1954, German rocket scientist Hermann Oberth revealed an internal West German government investigation, which he headed, that arrived at an extraterrestrial conclusion, but this study was never made public. Classified, internal reports by the Canadian Project Magnet in 1952 and 1953 also assigned high probability to extraterrestrial origins. Publicly, however, Project Magnet, nor later Canadian defense studies, ever stated such a conclusion.

Some public government conclusions have indicated physical reality but stopped short of concluding extraterrestrial origins, though not dismissing the possibility. Examples are the Belgian military investigation into large triangles over their airspace in 1989-1991 and the recent 2009 Uruguay Air Force study conclusion (see below).

Some private studies have been neutral in their conclusions, but argued the inexplicable core cases called for continued scientific study. Examples are the Sturrock Panel study of 1998 and the 1970 AIAA review of the Condon Report.

American investigations

Following the large U.S. surge in sightings in June and early July 1947, on July 9, 1947, Army Air Force (AAF) intelligence, in cooperation with the FBI, began a formal investigation into selected best sightings with characteristics that could not be immediately rationalized, which included Kenneth Arnold’s and that of the United Airlines crew. The AAF used "all of its scientists" to determine whether or not "such a phenomenon could, in fact, occur". The research was "being conducted with the thought that the flying objects might be a celestial phenomenon," or that "they might be a foreign body mechanically devised and controlled."^[35] Three weeks later in a preliminary defense estimate, the air force investigation decided that, "This ‘flying saucer’ situation is not all imaginary or seeing too much in some natural phenomenon. Something is really flying around."^[36]

A further review by the intelligence and technical divisions of the Air Materiel Command at Wright Field reached the same conclusion, that "the phenomenon is something real and not visionary or fictitious," that there were objects in the shape of a disc, metallic in appearance, and as big as man-made aircraft. They were characterized by "extreme rates of climb [and] maneuverability," general lack of noise, absence of trail, occasional formation flying, and "evasive" behavior "when sighted or contacted by friendly aircraft and radar," suggesting a controlled craft. It was thus recommended in late September 1947 that an official Air Force investigation be set up to investigate the phenomenon. It was also recommended that other government agencies should assist in the investigation.^[37]

This led to the creation of the Air Force’s Project Sign at the end of 1947, one of the earliest government studies to come to a secret extraterrestrial conclusion. In August 1948, Sign investigators wrote a top-secret intelligence estimate to that effect. The Air Force Chief of Staff Hoyt Vandenberg ordered it destroyed. The existence of this suppressed report was revealed by several insiders who had read it, such as astronomer and USAF consultant Dr. J. Allen Hynek and Capt. Edward J. Ruppelt, the first head of the USAF's Project Blue Book.^[38]

Project Sign was dismantled and became Project Grudge at the end of 1948. Angered by the low quality of investigations by Grudge, the Air Force Director of Intelligence reorganized it as Project Blue Book in late 1951, placing Ruppelt in charge. Blue Book closed down in 1970, using the Condon Commission's negative conclusion as a rationale, ending the official Air Force UFO investigations. However, a 1969 USAF document, known as the Bolender memo, plus later government documents revealed that nonpublic U.S. government UFO investigations continued after 1970. The Bollender memo first stated that "reports of unidentified flying objects that could affect national security… are not part of the Blue Book system," indicating that more serious UFO incidents were already handled outside of the public Blue Book investigation. The memo then added, "reports of UFOs which could affect national security would continue to be handled through the standard Air Force procedures designed for this purpose." ^[39] In addition, in the late 1960s, there was a chapter on UFOs at the U.S. Air Force Academy in their Space Sciences course, giving serious consideration to possible extraterrestrial origins. When word of the curriculum became public, the Air Force in 1970 put out a statement the book was outdated and that cadets were now being informed of Condon's negative conclusion instead. ^[40]

Use of UFO instead of the popular flying saucer was first suggested in 1952 by Ruppelt, who felt that flying saucer did not reflect the diversity of the sightings. Ruppelt suggested that UFO should be pronounced as a word — you-foe. However it is generally pronounced by forming each letter: U.F.O. His term was quickly adopted by the Air Force, which also briefly used "UFOB" circa 1954, for Unidentified Flying Object. Ruppelt recounted his experiences with Project Blue Book in his memoir, The Report on Unidentified Flying Objects (1956), also the first book to use the term.^[41]

Air Force Regulation 200-2,^[42] issued in 1953 and 1954, defined an Unidentified Flying Object ("UFOB") as "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." The regulation also said UFOBs were to be investigated as a "possible threat to the security of the United States" and "to determine technical aspects involved." As to what the public was to be told, "it is permissible to inform news media representatives on UFOB's when the object is positively identified as a familiar object," but "For those objects which are not explainable, only the fact that ATIC [Air Technical Intelligence Center] will analyze the data is worthy of release, due to many unknowns involved." ^[43][44]

Well known American investigations include:

• Project Blue Book, previously Project Sign and Project Grudge, conducted by the United States Air Force from 1947 until 1969
• The secret U.S. Army/Air Force Project Twinkle investigation into green fireballs (1948–1951)
• Ghost rockets investigations by the Swedish, U.K., U.S., and Greek militaries (1946–1947)
• The secret CIA Robertson Panel (1953)
• The secret USAF Project Blue Book Special Report No. 14 by the Battelle Memorial Institute (1951–1954)
• The Brookings Report (1960), commissioned by NASA
• The public Condon Committee (1966–1968)
• The private, internal RAND Corporation study (1968)^[45]
• The private Sturrock Panel (1998)

Another early U.S. Army study, established sometime in the 1940s and of which little is known, was called the Interplanetary Phenomenon Unit (IPU). In 1987, British UFO researcher Timothy Good received a letter confirming the existence of the IPU from the Army Director of Counter-intelligence, in which it was stated, "… the aforementioned Army unit was disestablished during the late 1950s and never reactivated. All records pertaining to this unit were surrendered to the U.S. Air Force Office of Special Investigations in conjunction with operation BLUEBOOK." The IPU records have never been released.^[46]

Thousands of documents released under FOIA also indicate that many U.S. intelligence agencies collected (and still collect) information on UFOs, including the Defense Intelligence Agency (DIA), FBI, CIA, National Security Agency (NSA), as well as military intelligence agencies of the Army and Navy, in addition to the Air Force.^[47]

The investigation of UFOs has also attracted many civilians, who in the U.S formed research groups such as National Investigations Committee On Aerial Phenomena (NICAP, active 1956-1980), Aerial Phenomena Research Organization (APRO, 1952-1988), Mutual UFO Network (MUFON, 1969-), and Center for UFO Studies (CUFOS, 1973-).

Reverse engineering

Attempts have been made to reverse engineer the possible physics behind UFOs through analysis of both eyewitness reports and the physical evidence, on the assumption that they are powered vehicles. Examples are former NASA and nuclear engineer James McCampbell in his book Ufology,^[90] NACA/NASA engineer Paul R. Hill in his book Unconventional Flying Objects, and German rocketry pioneer Hermann Oberth^[91]. Among subjects tackled by McCampbell, Hill, and Oberth was the question of how UFOs can fly at supersonic speeds without creating a sonic boom. McCampbell's proposed solution is microwave plasma parting the air in front of the craft. In contrast, Hill and Oberth believed UFOs utilize an as yet unknown anti-gravity field to accomplish the same thing as well as provide propulsion and protection of occupants from the effects of high acceleration.^[92]

UFO categorization

This section does not cite any references or sources. Please help improve this article by adding citations to reliable sources. Unverifiable material may be challenged and removed. (March 2009)

Some ufologists recommend that observations be classified according to the features of the phenomenon or object that are reported or recorded. Typical categories include:

• Saucer, toy-top, or disk-shaped "craft" without visible or audible propulsion. (day and night)
• Large triangular "craft" or triangular light pattern, usually reported at night.
• Cigar-shaped "craft" with lighted windows (Meteor fireballs are sometimes reported this way, but are very different phenomena).
• Other: chevrons, (equilateral) triangles, crescent, boomerangs, spheres (usually reported to be shining, glowing at night), domes, diamonds, shapeless black masses, eggs, pyramids and cylinders, classic "lights".

Popular UFO classification systems include the Hynek system, created by J. Allen Hynek, and the Vallée system, created by Jacques Vallée.

Hynek's system involves dividing the sighted object by appearance, subdivided further into the type of "close encounter" (a term from which the film director Steven Spielberg derived the title of his UFO movie, "Close Encounters of the Third Kind").

Jacques Vallée's system classifies UFOs into five broad types, each with from three to five subtypes that vary according to type.

Conspiracy theories

UFOs are sometimes an element of elaborate conspiracy theories in which governments are said to be intentionally covering up the existence of aliens, or sometimes collaborating with them. There are many versions of this story; some are exclusive, while others overlap with various other conspiracy theories.

In the U.S., an opinion poll conducted in 1997 suggested that 80 % of Americans believed the U.S. government was withholding such information.^[93][94] Various notables have also expressed such views. Some examples are astronauts Gordon Cooper and Edgar Mitchell, Senator Barry Goldwater, Vice Admiral Roscoe H. Hillenkoetter (the first CIA director), Lord Hill-Norton (former British Chief of Defense Staff and NATO head), the 1999 high-level French COMETA report by various French generals and aerospace experts, and Yves Sillard (former director of the French space agency CNES, new director of French UFO research organization GEIPAN).^[95]

It has also been suggested by a few paranormal authors that all or most human technology and culture is based on extraterrestrial contact. See also ancient astronauts.

Allegations of evidence suppression

Some^[who?] also contend regarding physical evidence that it exists abundantly but is swiftly and sometimes clumsily suppressed by governments, aiming to insulate a population they regard as unprepared for the social, theological, and security implications of such evidence^{[citation needed]}. See the Brookings Report.

There have been allegations of suppression of UFO related evidence for many decades. There are also conspiracy theories that claim that physical evidence might have been removed and/or destroyed/suppressed by some governments. (See also Men in Black)

Famous hoaxes

• The Maury Island Incident
• The Ummo affair, a decades-long series of detailed letters and documents allegedly from extraterrestrials. The total length of the documents is at least 1000 pages, and some estimate that further undiscovered documents may total nearly 4000 pages. A José Luis Jordan Pena came forward in the early nineties claiming responsibility for the phenomenon, and most^[who?] consider there to be little reason to challenge his claims.^[96]
• George Adamski over the space of two decades made various claims about his meetings with telepathic aliens from nearby planets. He claimed that photographs of the far side of the moon taken by a Soviet orbital probe in 1959 were fake, and that there were cities, trees and snow-capped mountains on the far side of the moon. Among copycats was a shadowy British figure named Cedric Allingham.
• In 1987/1988 Ed Walters allegedly perpetrated a hoax in Gulf Breeze, Florida. Walters claimed at first having seen a small UFO flying near his home, and then in a second incident seeing the same UFO and a small alien being standing by his back door after being alerted by his dog. Several photographs were taken of the craft, but none of the being. Three years later, in 1990, after the Walters family had moved, the new residents discovered a model of a UFO poorly hidden in the attic that bore an undeniable resemblance to the craft in Walters' photographs. Various witnesses and detractors came forward after the local Pensacola newspaper printed a story about the discovered model, and some investigators^[who?] now consider the sightings to be a hoax. In addition, a six-figure television miniseries and book deal were nearly struck with Walters.
• Warren William (Billy) Smith, A popular writer and confessed hoaxster.^[97]

A Ufologists who disagrees that the Ed Walters Gulf Breeze photos are hoaxes is naval optical physicist Dr. Bruce Maccabee. He investigated the incident, analyzed the various photos and deemed them authentic.^[98] Maccabee claimed he himself was among independent witnesses of some of the Gulf Breeze sightings.^[99]

UFOs in popular culture

Main article: UFOs in Fiction

UFOs constitute a widespread international cultural phenomenon of the last 60 years. Gallup polls rank UFOs near the top of lists for subjects of widespread recognition. In 1973, a survey found that 95 percent of the public reported having heard of UFOs, whereas only 92 percent had heard of US President Gerald Ford in a 1977 poll taken just nine months after he left the White House. (Bullard, 141) A 1996 Gallup poll reported that 71 percent of the United States population believed that the government was covering up information regarding UFOs. A 2002 Roper poll for the Sci Fi channel found similar results, but with more people believing UFOs were extraterrestrial craft. In that latest poll, 56 percent thought UFOs were real craft and 48 percent that aliens had visited the Earth. Again, about 70 percent felt the government was not sharing everything it knew about UFOs or extraterrestrial life.^{[100][101][102]} Another effect of the flying saucer type of UFO sightings has been Earth-made flying saucer craft in space fiction, for example the Earth spacecraft Starship C-57D in Forbidden Planet, and the saucer section of the USS Enterprise in Star Trek, and many others. For an excellent analysis of the interrelationship between popular culture and UFOs consult the research by psychologist Armando Simon, especially his contribution in Richard Haines' book, UFO Phenomena and the Behavioral Scientist.

COMPUTER HISTORY

A computer is a machine that manipulates data according to a set of instructions.

Although mechanical examples of computers have existed through much of recorded human history, the first resembling a modern computer were developed in the mid-20th century (1940–1945). The first electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers (PC).[1] Modern computers based on tiny integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into a wristwatch, and can be powered by a watch battery. Personal computers in their various forms are icons of the Information Age, what most people think of as a "computer", but the embedded computers found in devices ranging from fighter aircraft to industrial robots, digital cameras, and toys are the most numerous.

The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a personal digital assistant to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.


NASA COLUMBIA SUPER COMPUTER

History of computing

The first use of the word "computer" was recorded in 1613, referring to a person who carried out calculations, or computations, and the word continued to be used in that sense until the middle of the 20th century. From the end of the 19th century onwards though, the word began to take on its more familiar meaning, describing a machine that carries out computations.[3]

The history of the modern computer begins with two separate technologies—automated calculation and programmability—but no single device can be identified as the earliest computer, partly because of the inconsistent application of that term. Examples of early mechanical calculating devices include the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150–100 BC). Hero of Alexandria (c. 10–70 AD) built a mechanical theater which performed a play lasting 10 minutes and was operated by a complex system of ropes and drums that might be considered to be a means of deciding which parts of the mechanism performed which actions and when.[4] This is the essence of programmability.

The "castle clock", an astronomical clock invented by Al-Jazari in 1206, is considered to be the earliest programmable analog computer.[5] It displayed the zodiac, the solar and lunar orbits, a crescent moon-shaped pointer travelling across a gateway causing automatic doors to open every hour,[6][7] and five robotic musicians who played music when struck by levers operated by a camshaft attached to a water wheel. The length of day and night could be re-programmed to compensate for the changing lengths of day and night throughout the year.[5]

The end of the Middle Ages saw a re-invigoration of European mathematics and engineering. Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers, but none fit the modern definition of a computer, because they could not be programmed.

In 1801, Joseph Marie Jacquard made an improvement to the textile loom by introducing a series of punched paper cards as a template which allowed his loom to weave intricate patterns automatically. The resulting Jacquard loom was an important step in the development of computers because the use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of programmability.

It was the fusion of automatic calculation with programmability that produced the first recognizable computers. In 1837, Charles Babbage was the first to conceptualize and design a fully programmable mechanical computer, his analytical engine.[8] Limited finances and Babbage's inability to resist tinkering with the design meant that the device was never completed.

In the late 1880s Herman Hollerith invented the recording of data on a machine readable medium. Prior uses of machine readable media, above, had been for control, not data. "After some initial trials with paper tape, he settled on punched cards ..."[9] To process these punched cards he invented the tabulator, and the key punch machines. These three inventions were the foundation of the modern information processing industry. Large-scale automated data processing of punched cards was performed for the 1890 United States Census by Hollerith's company, which later became the core of IBM. By the end of the 19th century a number of technologies that would later prove useful in the realization of practical computers had begun to appear: the punched card, Boolean algebra, the vacuum tube (thermionic valve) and the teleprinter.

During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers.

Alan Turing is widely regarded to be the father of modern computer science. In 1936 Turing provided an influential formalisation of the concept of the algorithm and computation with the Turing machine. Of his role in the modern computer, Time Magazine in naming Turing one of the 100 most influential people of the 20th century, states: "The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working on an incarnation of a Turing machine." [10]

George Stibitz is internationally recognized as a father of the modern digital computer. While working at Bell Labs in November of 1937, Stibitz invented and built a relay-based calculator he dubbed the "Model K" (for "kitchen table", on which he had assembled it), which was the first to use binary circuits to perform an arithmetic operation. Later models added greater sophistication including complex arithmetic and programmability.

A succession of steadily more powerful and flexible computing devices were constructed in the 1930s and 1940s, gradually adding the key features that are seen in modern computers. The use of digital electronics (largely invented by Claude Shannon in 1937) and more flexible programmability were vitally important steps, but defining one point along this road as "the first digital electronic computer" is difficult (Shannon 1940). Notable achievements include:
EDSAC was one of the first computers to implement the stored program (von Neumann) architecture.

* Konrad Zuse's electromechanical "Z machines". The Z3 (1941) was the first working machine featuring binary arithmetic, including floating point arithmetic and a measure of programmability. In 1998 the Z3 was proved to be Turing complete, therefore being the world's first operational computer.
* The non-programmable Atanasoff–Berry Computer (1941) which used vacuum tube based computation, binary numbers, and regenerative capacitor memory. The use of regenerative memory allowed it to be much more compact then its peers (being approximately the size of a large desk or workbench), since intermediate results could be stored and then fed back into the same set of computation elements.
* The secret British Colossus computers (1943),[12] which had limited programmability but demonstrated that a device using thousands of tubes could be reasonably reliable and electronically reprogrammable. It was used for breaking German wartime codes.
* The Harvard Mark I (1944), a large-scale electromechanical computer with limited programmability.
* The U.S. Army's Ballistics Research Laboratory ENIAC (1946), which used decimal arithmetic and is sometimes called the first general purpose electronic computer (since Konrad Zuse's Z3 of 1941 used electromagnets instead of electronics). Initially, however, ENIAC had an inflexible architecture which essentially required rewiring to change its programming.

Several developers of ENIAC, recognizing its flaws, came up with a far more flexible and elegant design, which came to be known as the "stored program architecture" or von Neumann architecture. This design was first formally described by John von Neumann in the paper First Draft of a Report on the EDVAC, distributed in 1945. A number of projects to develop computers based on the stored-program architecture commenced around this time, the first of these being completed in Great Britain. The first to be demonstrated working was the Manchester Small-Scale Experimental Machine (SSEM or "Baby"), while the EDSAC, completed a year after SSEM, was the first practical implementation of the stored program design. Shortly thereafter, the machine originally described by von Neumann's paper—EDVAC—was completed but did not see full-time use for an additional two years.

Nearly all modern computers implement some form of the stored-program architecture, making it the single trait by which the word "computer" is now defined. While the technologies used in computers have changed dramatically since the first electronic, general-purpose computers of the 1940s, most still use the von Neumann architecture.
Microprocessors are miniaturized devices that often implement stored program CPUs.

Computers using vacuum tubes as their electronic elements were in use throughout the 1950s, but by the 1960s had been largely replaced by transistor-based machines, which were smaller, faster, cheaper to produce, required less power, and were more reliable. The first transistorised computer was demonstrated at the University of Manchester in 1953.[13] In the 1970s, integrated circuit technology and the subsequent creation of microprocessors, such as the Intel 4004, further decreased size and cost and further increased speed and reliability of computers. By the late 1970s, many products such as video recorders contained dedicated computers called microcontrollers, and they started to appear as a replacement to mechanical controls in domestic appliances such as washing machines. The 1980s witnessed home computers and the now ubiquitous personal computer. With the evolution of the Internet, personal computers are becoming as common as the television and the telephone in the household.

Modern smartphones are fully-programmable computers in their own right, and as of 2009 may well be the most common form of such computers in existence.





Stored program architecture

The defining feature of modern computers which distinguishes them from all other machines is that they can be programmed. That is to say that a list of instructions (the program) can be given to the computer and it will store them and carry them out at some time in the future.

In most cases, computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc. These instructions are read from the computer's memory and are generally carried out (executed) in the order they were given. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called "jump" instructions (or branches). Furthermore, jump instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external event. Many computers directly support subroutines by providing a type of jump that "remembers" the location it jumped from and another instruction to return to the instruction following that jump instruction.

Program execution might be likened to reading a book. While a person will normally read each word and line in sequence, they may at times jump back to an earlier place in the text or skip sections that are not of interest. Similarly, a computer may sometimes go back and repeat the instructions in some section of the program over and over again until some internal condition is met. This is called the flow of control within the program and it is what allows the computer to perform tasks repeatedly without human intervention.

Comparatively, a person using a pocket calculator can perform a basic arithmetic operation such as adding two numbers with just a few button presses. But to add together all of the numbers from 1 to 1,000 would take thousands of button presses and a lot of time—with a near certainty of making a mistake. On the other hand, a computer may be programmed to do this with just a few simple instructions. For example:

mov #0,sum ; set sum to 0
mov #1,num ; set num to 1
loop: add num,sum ; add num to sum
add #1,num ; add 1 to num
cmp num,#1000 ; compare num to 1000
ble loop ; if num <= 1000, go back to 'loop'
halt ; end of program. stop running

Once told to run this program, the computer will perform the repetitive addition task without further human intervention. It will almost never make a mistake and a modern PC can complete the task in about a millionth of a second.[14]

However, computers cannot "think" for themselves in the sense that they only solve problems in exactly the way they are programmed to. An intelligent human faced with the above addition task might soon realize that instead of actually adding up all the numbers one can simply use the equation

1+2+3+...+n = {{n(n+1)} \over 2}

and arrive at the correct answer (500,500) with little work.[15] In other words, a computer programmed to add up the numbers one by one as in the example above would do exactly that without regard to efficiency or alternative solutions.

Programs

In practical terms, a computer program may run from just a few instructions to many millions of instructions, as in a program for a word processor or a web browser. A typical modern computer can execute billions of instructions per second (gigahertz or GHz) and rarely make a mistake over many years of operation. Large computer programs consisting of several million instructions may take teams of programmers years to write, and due to the complexity of the task almost certainly contain errors.

Errors in computer programs are called "bugs". Bugs may be benign and not affect the usefulness of the program, or have only subtle effects. But in some cases they may cause the program to "hang"—become unresponsive to input such as mouse clicks or keystrokes, or to completely fail or "crash". Otherwise benign bugs may sometimes may be harnessed for malicious intent by an unscrupulous user writing an "exploit"—code designed to take advantage of a bug and disrupt a program's proper execution. Bugs are usually not the fault of the computer. Since computers merely execute the instructions they are given, bugs are nearly always the result of programmer error or an oversight made in the program's design.[16]

In most computers, individual instructions are stored as machine code with each instruction being given a unique number (its operation code or opcode for short). The command to add two numbers together would have one opcode, the command to multiply them would have a different opcode and so on. The simplest computers are able to perform any of a handful of different instructions; the more complex computers have several hundred to choose from—each with a unique numerical code. Since the computer's memory is able to store numbers, it can also store the instruction codes. This leads to the important fact that entire programs (which are just lists of instructions) can be represented as lists of numbers and can themselves be manipulated inside the computer just as if they were numeric data. The fundamental concept of storing programs in the computer's memory alongside the data they operate on is the crux of the von Neumann, or stored program, architecture. In some cases, a computer might store some or all of its program in memory that is kept separate from the data it operates on. This is called the Harvard architecture after the Harvard Mark I computer. Modern von Neumann computers display some traits of the Harvard architecture in their designs, such as in CPU caches.

While it is possible to write computer programs as long lists of numbers (machine language) and this technique was used with many early computers,[17] it is extremely tedious to do so in practice, especially for complicated programs. Instead, each basic instruction can be given a short name that is indicative of its function and easy to remember—a mnemonic such as ADD, SUB, MULT or JUMP. These mnemonics are collectively known as a computer's assembly language. Converting programs written in assembly language into something the computer can actually understand (machine language) is usually done by a computer program called an assembler. Machine languages and the assembly languages that represent them (collectively termed low-level programming languages) tend to be unique to a particular type of computer. For instance, an ARM architecture computer (such as may be found in a PDA or a hand-held videogame) cannot understand the machine language of an Intel Pentium or the AMD Athlon 64 computer that might be in a PC.[18]

Though considerably easier than in machine language, writing long programs in assembly language is often difficult and error prone. Therefore, most complicated programs are written in more abstract high-level programming languages that are able to express the needs of the computer programmer more conveniently (and thereby help reduce programmer error). High level languages are usually "compiled" into machine language (or sometimes into assembly language and then into machine language) using another computer program called a compiler.[19] Since high level languages are more abstract than assembly language, it is possible to use different compilers to translate the same high level language program into the machine language of many different types of computer. This is part of the means by which software like video games may be made available for different computer architectures such as personal computers and various video game consoles.

The task of developing large software systems presents a significant intellectual challenge. Producing software with an acceptably high reliability within a predictable schedule and budget has historically been difficult; the academic and professional discipline of software engineering concentrates specifically on this problem.

Manchester United F.C.

Manchester United Football Club is an English football club, based at Old Trafford in Trafford, Greater Manchester, and is one of the most popular football clubs in the world. The club was a founding member of the Premier League in 1992, and has played in the top division of English football since 1938, with the exception of the 1974–75 season. Average attendances at the club have been higher than any other team in English football for all but six seasons since 1964–65.[3]

Manchester United are the reigning English champions and Club World Cup holders, having won the 2008–09 Premier League and the 2008 FIFA Club World Cup. The club is one of the most successful in the history of English football and has won 22 major honours since Alex Ferguson became manager in November 1986. In 1968, they became the first English club to win the European Cup, beating Benfica 4–1. They won a second European Cup as part of a Treble in 1999, before winning their third in 2008. The club holds the joint record for the most English league titles with 18 and also holds the record for the most FA Cup wins with 11.[4]

Since the late 1990s, the club has been one of the richest in the world with the highest revenue of any football club,[5] and is currently ranked as the richest and most valuable club in any sport, with an estimated value of £897 million (€1.333 billion / $1.8 billion) as of September 2008.[6] Manchester United was a founding member of the now defunct G-14 group of Europe's leading football clubs,[7] and its replacement, the European Club Association.[8]

Alex Ferguson has been manager of the club since 6 November 1986, joining from Aberdeen after the departure of Ron Atkinson.[9] The current club captain is Gary Neville, who succeeded Roy Keane in November 2005

Chart showing the progress of Manchester United F.C. through the English football league system since joining as Newton Heath in 1892–93 to 2007–08

The club was formed as Newton Heath L&YR F.C. in 1878 as the works team of the Lancashire and Yorkshire Railway depot at Newton Heath. The club's shirts were green and gold halves. They played on a small, dilapidated field on North Road for fifteen years, before moving to Bank Street in the nearby town of Clayton in 1893. The club had entered The Football League the previous year and began to sever its links with the rail depot, becoming an independent company, appointing a club secretary and dropping the "L&YR" from their name to become simply Newton Heath F.C.. Not long afterwards, in 1902, the club neared bankruptcy, with debts of over £2,500. At one point, their Bank Street ground was even closed by the bailiffs.[11]

Just before having to be shut down for good, the club received a sizeable investment from J. H. Davies, the managing director of Manchester Breweries.[12] Legend goes that Harry Stafford, the club captain, was showing off his prized St. Bernard dog at a club fund-raiser, when Davies approached him to buy the dog. Stafford declined, but was able to persuade Davies to invest in the club and become club chairman.[13] It was decided at one of the early board meetings that the club required a change of name to reflect the fresh start they had been afforded. Manchester Central and Manchester Celtic were among the names suggested, before Louis Rocca, a young immigrant from Italy, said "Gentlemen, why don't we call ourselves Manchester United?"[14] The name stuck, and Manchester United officially came into existence on 26 April 1902. Davies also decided it would be appropriate to change the club's colours, abandoning the green and gold halves of Newton Heath, and picking red and white to be the colours of Manchester United.

Ernest Mangnall was appointed as club secretary after James West had resigned as manager on 28 September 1902. Mangnall was charged with trying to get the club into the First Division, and fell just short of that target at the first attempt, finishing in fifth in Division Two. Mangnall decided that it was necessary to bring in some fresh faces to the club, and signed players such as Harry Moger in goal, Dick Duckworth at half-back and Jack Picken up front, but it was another new half-back by the name of Charlie Roberts who made the biggest impact. He cost the club a then-record £750 from Grimsby Town in April 1904, and helped them to a third place finish in the 1903–04 season, just a point short of the second promotion place.

It was not long, however, before the club was at last promoted to the First Division for the first time under their new name, finishing in second place in the 1905–06 Second Division. A season of consolidation followed, with the club finishing in eighth, before they finally won their first league title in 1908. Manchester City had recently been under investigation for paying some of their players a salary over the amount allowed by FA regulations. They were fined £250 and eighteen of their players were banned from playing for them ever again. United were quick to pounce on the situation, picking up Billy Meredith (the Welsh Wizard) and Sandy Turnbull, amongst others. The new boys from across town were ineligible to play until New Year's Day 1907, due to their suspension, so it was left until the 1907–08 season for them to make a proper impact on United's bid for the title. And that they did, getting the campaign off to a storming start, with a 2–1 victory over Sheffield United, beginning a run of ten consecutive victories. Despite a shaky end to the season, United managed to hang on and finished the season nine points ahead of their closest rivals, Aston Villa.

The following season began with United picking up another piece of silverware, the first ever Charity Shield,[15] and ended with another, the club's first FA Cup title, sowing the seeds for what has become a record number of FA Cup titles. Just as they were in the club's first title-winning campaign, Turnbull and Meredith were instrumental in this season, Turnbull scoring the winner in the FA Cup Final. The club had to wait another two years before winning any more silverware, winning the First Division for the second time in the 1910–11 season. In the meantime, United moved to their new ground at Old Trafford. They played their first game there on 19 February 1910 against Liverpool, but lost 4–3 having thrown away a 3–0 lead. They then went trophyless again in the 1911–12 season, which not only proved to be the last with Mangnall in charge (he moved to Manchester City after ten years with United), but also the last time the club won the First Division for 41 years, the longest they have gone without winning the league in their history.

For the next ten years, the club went into a state of gradual decline before being relegated back down to Division Two in 1922. They were promoted again in 1925, but struggled to get into the top half of the table, and were relegated again in 1931. In the eight years leading up to the Second World War, the club became somewhat of a yo-yo club, reaching their all-time lowest position of 20th in Division Two in 1934. They were promoted and relegated once again before being promoted in the penultimate season before the Second World War. They guaranteed their place in the top flight for after the war by finishing in 14th in the 1938–39 season.

The Busby years (1945–1969)
Main article: History of Manchester United F.C. (1945–1969)

1945 saw the appointment of Matt Busby to the manager's post at Old Trafford. He took an uncommon approach to his job, insisting that he be allowed to pick his own team, choose which players to sign and direct the team's training sessions himself. He had already missed out on the manager's job at his former club, Liverpool, because the club saw those tasks as jobs for the directors, but United decided to take a chance on Busby's innovative ideas. Busby's first signing was not a player, but a new assistant manager by the name of Jimmy Murphy. The risk the club had taken in appointing Busby paid immediate dividends, with the club finishing second in the league in 1947, 1948 and 1949 and winning the FA Cup in 1948, thanks in part to the locally born trio of Stan Pearson, Jack Rowley and Charlie Mitten (Rowley and Pearson both scored in the 1948 Cup Final), as well as the centre-half from the North-East, Allenby Chilton.

Charlie Mitten had fled to Colombia in search of a better salary, but the remainder of United's old heads managed to win the First Division title back in 1952. Busby knew, however, that football teams required more than just experience in the side, and so he adopted a policy of bringing in players from the youth team whenever possible. At first, the young players such as Roger Byrne, Bill Foulkes, Mark Jones and Dennis Viollet, took time to bed themselves into the side, sliding to a low of eighth place in 1953, but the team won the league again in 1956 with an average age of only 22, scoring 103 goals in the process. The youth policy set in motion by Busby has now become a hallmark of the most successful periods in the club's history (the mid-1950s, mid-to-late-1960s and 1990s). Busby's original "crop" of youth players was referred to as the Busby Babes, the jewel in the crown of which was a wing-half named Duncan Edwards. The boy from Dudley in the West Midlands made his United début at the age of just 16 back in 1953. It was said that Edwards could play at any position on the field, and many who saw him play said that he was the greatest player ever. The following season, 1956–57, they won the league again and reached the FA Cup final, losing to Aston Villa. They also became the first English team to compete in the European Cup, at the behest of the FA, who had denied Chelsea the same opportunity the previous season, and reached the semi-final, only to be knocked out by Real Madrid. En route to the semi-final, United also recorded a win that still stands as their biggest win in all competitions, beating Belgian champions Anderlecht 10–0 at Maine Road.

Tragedy struck the following season, when the plane carrying the team home from a European Cup match crashed on take-off at a refuelling stop in Munich, Germany. The Munich air disaster of 6 February 1958 claimed the lives of eight players – Geoff Bent, Roger Byrne, Eddie Colman, Duncan Edwards, Mark Jones, David Pegg, Tommy Taylor and Liam "Billy" Whelan – and another fifteen passengers, including United staff members Walter Crickmer, Bert Whalley and Tom Curry.[16] There had already been two attempted take-offs before the fatal third, which was caused by a build-up of slush at the end of the runway slowing the plane down to a speed insufficient for take-off. The plane skidded off the end of the runway, through a fence and into an unoccupied house. United goalkeeper Harry Gregg managed to maintain consciousness after the crash, and through fear of the plane exploding at any second, he grabbed both Bobby Charlton – who had made his United début less than 18 months earlier – and Dennis Viollet by their waistbands and dragged them to safety. Seven United players died at the scene, while Duncan Edwards died a fortnight later in hospital. Right-winger Johnny Berry also survived the accident, but injuries sustained in the accident brought his football career to a premature end. Matt Busby was not given much hope of survival by the Munich doctors, and was even given the Last Rites at one point, but recovered miraculously and was finally let out of hospital after having spent over two months there.

There were rumours of the club folding and withdrawing from all competitions, but with Jimmy Murphy taking over as manager while Busby recovered from his injuries, the club continued playing with a makeshift side. Despite the accident, they reached the FA Cup final again, where they lost to Bolton Wanderers. At the end of the season, UEFA offered the FA the opportunity to submit both United and the eventual champions, Wolverhampton Wanderers, for the 1958–59 European Cup as a tribute to the victims, but the FA declined. United managed to push Wolves right to the wire the following season, finishing in a creditable second place; not bad for a team that had lost nine first-team players to the Munich air disaster.

Busby rebuilt the team throughout the early 1960s, signing players such as Denis Law and Pat Crerand, all the while nurturing his new generation of youngsters. Perhaps the most famous of this new batch was a young man from Belfast named George Best. Best had a natural athleticism rarely seen, but his most valuable asset was his close control of a football. His quick feet allowed him to pass through almost any gap in the opposition defence, no matter how small. The team won the FA Cup in 1963, albeit finishing in 19th place in the First Division. The FA Cup triumph seemed to reinvigorate the players, who helped the club to second place in 1964, and then went one better by winning the league in 1965 and 1967. United won the European Cup in 1968, beating Eusébio's SL Benfica 4–1 in the final, becoming the first English club to win the competition. This United team was notable for containing three European Footballers of the Year: Bobby Charlton, Denis Law and George Best. Matt Busby resigned as manager in 1969 and was replaced by the reserve team coach and former United player, Wilf McGuinness.

1969–1986

United struggled to replace Busby, and the team struggled under Wilf McGuinness in the 1969–70 season, finishing a disappointing eighth, and following a poor start to the 1970–71 season, McGuinness was demoted back to the position of reserve team coach. Busby was coaxed back to the club, albeit only for six months. Results got better with Busby's guidance, but he finally left the club for the last time in the summer of 1971. In the meantime, United had lost a number of high-profile players such as Nobby Stiles and Pat Crerand.

Despite approaching Celtic's European Cup-winning manager, Jock Stein, for the manager's job – Stein had agreed a verbal contract to join United, but pulled out at the last minute – Frank O'Farrell was appointed as Busby's successor. However, like McGuinness, O'Farrell only lasted less than 18 months, the only difference between the two being that O'Farrell reacted to the team's poor form by bringing in some fresh talent, most specifically Martin Buchan from Aberdeen for £125,000. Tommy Docherty became manager at the end of 1972. Docherty, or "the Doc", saved United from relegation that season but United were relegated in 1974, by which time the golden trio of Best, Law and Charlton had left the club. Denis Law had moved to Manchester City in the summer of 1973, and ended up scoring the goal that many people say relegated United, and politely refused to celebrate the goal with his team mates. Players like Lou Macari, Stewart Houston and Brian Greenhoff were brought in to replace Best, Law and Charlton, but none could live up to the stature of the three that came before.

The team won promotion at the first attempt, with a young Steve Coppell making his début towards the end of that season, having joined from Tranmere Rovers, and reached the FA Cup final in 1976, but were beaten by Southampton. They reached the final again in 1977, beating Liverpool 2–1. In spite of this success and his popularity with the supporters, Docherty was sacked soon after the final when he was found to have had an affair with the physiotherapist's wife.

Dave Sexton replaced Docherty as manager in the summer of 1977, and made the team play in a more defensive formation. This style was unpopular with supporters, who were used to the attacking football preferred by Docherty and Busby. Major signings under Sexton included Joe Jordan, Gordon McQueen, Gary Bailey and Ray Wilkins, but Sexton's defensive United failed to break out of mid-table obscurity, only once finishing in the top two, and only reached the FA Cup final once, losing to Arsenal. Because of this lack of trophies, Sexton was sacked in 1981, even though he won his last seven games in charge.

He was replaced by the flamboyant Ron Atkinson, whose extrovert attitude was reflected in the clubs he managed. He immediately broke the British record transfer fee to sign Bryan Robson from his old club, West Brom. Robson would come to be touted in the future as United's best midfield player since Duncan Edwards. Atkinson's team featured new signings such as Jesper Olsen, Paul McGrath and Gordon Strachan playing alongside former youth team players Norman Whiteside and Mark Hughes. United won the FA Cup twice in three years, in 1983 and 1985, and were overwhelming favourites to win the league in the 1985–86 season after winning their first ten league games, opening a ten-point gap over their rivals as early as October. The team's form collapsed, however, and United finished the season in fourth place. The poor form continued into the following season, and with United on the edge of the First Division's relegation zone by the beginning of November 1986, Atkinson was sacked.

Alex Ferguson era, pre-Treble (1986–1998)
Main article: History of Manchester United F.C. (1986–1998)
Alex Ferguson has been manager of Manchester United since November 1986.

Alex Ferguson arrived from Aberdeen to replace Atkinson on the very day that Atkinson was sacked, bringing with him his assistant manager, Archie Knox. Although his first match in charge, against Oxford United on 8 November 1986, resulted in a 2–0 defeat, Ferguson guided the club to an 11th place finish in the league. A second place finish in 1987–88, with Brian McClair becoming the first United player since George Best to score twenty league goals in a season, may have given fans a tiny glimpse of the future, but they soon returned to mediocrity with another 11th-place finish in 1989.

Many of Ferguson's signings did not reach the expectations of the fans, and the manager was reportedly on the verge of being sacked at the beginning of 1990, with many believing that defeat to Nottingham Forest in the FA Cup Third Round would seal his fate. A 56th-minute goal from Mark Robins won the match for United and started them on a cup run that would take them all the way to the final at Wembley, where they beat Crystal Palace 1–0 in a replay after a 3–3 draw in the original match. The following year, United reached the final of the League Cup, but lost 1–0 to former manager Ron Atkinson's Sheffield Wednesday team. However, the season was capped by the club's first Cup Winners' Cup title, beating Barcelona 2–1 in the final in Rotterdam. The Cup Winners' Cup triumph allowed the team to play in the 1991 UEFA Super Cup, in which they beat European Cup holders Red Star Belgrade 1–0 at Old Trafford. The match should have been played over two legs, but, due to political unrest in Yugoslavia at the time, UEFA decided that only the Old Trafford leg would be played. A second consecutive League Cup final appearance followed in 1992, with United this time beating Nottingham Forest 1–0 at Wembley.

Meanwhile, events were taking place off the pitch around the turn of the decade, as chairman Martin Edwards attempted to offload the club to property tycoon Michael Knighton in 1989. The £20 million deal was all but confirmed, with Knighton even taking to the Old Trafford pitch in full Manchester United kit and performing a few keepie uppies before belting the ball into the goal at the Stretford End. Knighton was given access to the club's financial records, but, before the deal could be finalised, his financial backers pulled out and the deal was cancelled. However, since Knighton now had insider knowledge of the club, he was given a place on the club's board in exchange for his silence about the matter. In 1991, requiring some extra financial support in the wake of the Taylor Report, the club floated on the London Stock Exchange with a valuation of £47 million,[17] bringing its finances into the public eye. Martin Edwards retained his position as chairman, but the club was now publicly owned.

The summer of 1991 also saw the arrival of Danish goalkeeper Peter Schmeichel, whose 17 league clean sheets gave United the best defensive record in the First Division in 1991–92, helping them to a second-place finish behind Leeds United, within whose ranks was a certain French maverick named Eric Cantona. Alex Ferguson recognised United's need for a striker as a foil for Mark Hughes and Brian McClair, and had tried – and failed – a number of times to sign Sheffield Wednesday striker David Hirst, but when Leeds manager Howard Wilkinson rang Martin Edwards in November 1992 to enquire about the availability of Denis Irwin, the conversation quickly turned to Cantona. To Edwards' and Ferguson's surprise, the two clubs were able to agree upon a fee of £1.2 million for the enigmatic Frenchman. Cantona's arrival provided the crucial spark for United, helping the team to their first league title since 1967. After the signing of Roy Keane from Nottingham Forest in July 1993, United won a second consecutive title for the first time since 1957 the following year, before winning the FA Cup to complete the first "Double" in the club's history. That same year, however, the club went into mourning following the death of former manager and club director Matt Busby, who died on 20 January 1994.

The 1994–95 season was to be the club's first trophyless season since 1988–89, although they managed to take the title race down to the final week of the season and reached the final of the FA Cup, where they lost to Everton. Andy Cole was signed from Newcastle United for a British record fee of £6 million plus Keith Gillespie. However, the game after Cole's United debut, Eric Cantona received an eight month suspension for jumping into the crowd and assaulting Crystal Palace supporter Matthew Simmons, who had given Cantona racial abuse as he left the field, in United's game at Selhurst Park. Cantona's suspension has been cited by some as the reason why United were unable to complete a hat-trick of league titles that season. The season's relative failure prompted Ferguson into some major restructuring of the team, selling Paul Ince, Andrei Kanchelskis and Mark Hughes and replacing them with players from the club's youth team, including David Beckham, Gary Neville, Phil Neville and Paul Scholes. After the club's 3–1 defeat to Aston Villa on the opening day of the 1995–96 season, television pundit Alan Hansen famously declared "you'll never win anything with kids."[18] The new players, several of whom quickly became regular internationals for England, responded well and, buoyed by Cantona's return in October 1995, United became the first English club to have won the double twice, a feat that would be nicknamed the "Double Double".[19]

Captain Steve Bruce left for Birmingham City in July 1996, and Alex Ferguson named Eric Cantona as the new club captain. He led the team to a fourth league title in five years in 1996–97, before retiring from football at the age of 30 at the end of the season. Teddy Sheringham was brought in to replace him, and his iconic number 7 shirt was handed to David Beckham. They started the 1997–98 season well, but they lost five matches after Christmas and finished in second place, one point behind double-winners Arsenal. After a period without a regular challenger for the league title, this marked Arsenal's arrival as genuine title contenders for the next few years.

The 1998–99 season for Manchester United was the most successful season in English club football history as they became the only English team to win The Treble – winning the Premier League, FA Cup and UEFA Champions League in the same season.[20] After a very tense Premier League season, Manchester United won the title on the final day beating Tottenham Hotspur 2–1, whilst Arsenal won 1–0 against Aston Villa.[21] Winning the Premier League was the first part of the Treble in place, the one part that manager Alex Ferguson described as the hardest.[21] In the FA Cup Final United faced Newcastle United and won 2–0 with goals from Teddy Sheringham and Paul Scholes.[22] In the final match of that season, the 1999 UEFA Champions League Final they defeated Bayern Munich in what is considered one of the greatest comebacks ever witnessed, going into injury time a goal behind and then scoring twice to win 2–1.[20] Ferguson was subsequently knighted for his services to football.[23] Rounding out that record breaking year, Manchester United also won the Intercontinental Cup after beating Palmeiras 1–0 in Tokyo.[24]

After the Treble (1999–present)
Main article: History of Manchester United F.C. (1999–present)

United won the league in 2000 and 2001 but the press saw these seasons as failures as they failed to regain the European Cup. In 2000, Manchester United became one of 14 founder members of the G-14 group of leading European football clubs.[25] The club also declined to take part in the 1999–2000 FA Cup, instead competing in the inaugural FIFA Club World Championship in Brazil, citing pressure from the FA, UEFA and the England 2006 World Cup bid committee. Ferguson adopted more defensive tactics to make United harder to beat in Europe but it was not a success and United finished the 2001–02 Premier League season in third place. They regained the league the following season (2002–03) and started the following season well, but their form dropped significantly when Rio Ferdinand received a controversial eight month suspension for missing a drugs test. They did win the 2004 FA Cup, however, knocking out Arsenal (that season's eventual league champions) on their way to the final in which they beat Millwall.

The 2004–05 season was characterised by a failure to score goals, mainly due to the injury of striker Ruud van Nistelrooy and United finished the season trophyless and in third place in the league. This time, even the FA Cup eluded them as Arsenal beat United on penalties after a goalless draw after 120 minutes. Off the pitch, the main story was the possibility of the club being taken over and on 12 May 2005, American businessman Malcolm Glazer acquired a controlling interest in the club through his investment vehicle Red Football Ltd. in a takeover valuing the club at approximately £800 million (then approx. $1.5 billion).[26][27] On 16 May, he increased his share to the 75% necessary to de-list the club from the Stock Exchange, making it private again, and announced his intention to do so within 20 days.[27] On 8 June, he appointed his sons to the Manchester United board as non-executive directors.[28]

United made a poor start to the 2005–06 season, with midfielder Roy Keane leaving the club to join Celtic after publicly criticising several of his team-mates, and the club failed to qualify for the knockout phase of the UEFA Champions League for the first time in over a decade after losing to Portuguese team Benfica. Their season was also dealt cruel blows with injuries to key players such as Gabriel Heinze, Alan Smith, Ryan Giggs and Paul Scholes. However, they were prevented from being left empty-handed in successive seasons a disappointment not endured in the last 17 years – by winning the 2006 League Cup, beating newly promoted neighbours Wigan Athletic in the final 4–0. United also ensured a second-place finish and automatic Champions League qualification on the final day of the season by defeating Charlton Athletic 4–0. At the end of the 2005–06 season, one of United's key strikers, Ruud van Nistelrooy, left the club to join Real Madrid, due to a row with Alex Ferguson.[29]

In July 2006, the club announced a refinancing package. The total amount will be £660 million, on which interest payments will be £62 million a year.[30] This result of this new financing plan will be a 30% reduction of annual payments.[31] On the pitch, the 2006–07 season saw United return to the attacking style of football that was the cornerstone of their years of success in the late 1990s, scoring almost 20 more goals in 32 matches than second placed side Chelsea. In January 2007, United signed Henrik Larsson on a two-month loan from Swedish side Helsingborgs, and the striker played an important role in advancing United to the semi-finals of the Champions League,[32] with hopes for a second Treble; however, upon reaching the semi-finals, United lost to Milan 3–5 on aggregate.[33] Four years after their last title, United claimed back the Premier League title on 6 May 2007, after Chelsea drew away with Arsenal, leaving the Blues seven points behind with two games to go, following United's 1–0 victory in the Manchester derby the previous day, making it their ninth Premier League title in the 15 seasons of its existence. However, an unprecedented fourth Double was not to be, as Chelsea beat United 1–0 in extra time in the first FA Cup Final to be held at the new Wembley Stadium; the first to be held in England since the old stadium was demolished seven years earlier.

2007–08 saw United successfully complete the European double despite a poor start to the season, finding themselves in 17th place in the Premier League after three matches. However, on 11 May 2008, United retained the Premier League title with a win over Wigan Athletic. With title rivals Chelsea only able to draw with Bolton Wanderers, United finished the season two points clear. The club also reached the European Cup final for the third time in their history, having knocked out such clubs as Barcelona and Roma en-route to the final. They beat Chelsea 6–5 on penalties in the final in Moscow's Luzhniki Stadium, after a 1–1 draw in normal time on 21 May 2008. With this win, they earned their third European Cup title and kept up their record of never having lost a major European final. Coincidentally, this season marked the 100th year since Manchester United won their first League title, 50 years after the Munich air disaster and 40 years after Manchester United became the first ever English side to win the European Cup. The European Cup final also saw Ryan Giggs make his 759th appearance for the club, overtaking Bobby Charlton as the club's record appearance maker.

Before the start of the 2008–09 season, United competed in and won the 2008 FA Community Shield. United beat 2007-08 FA Cup winners Portsmouth 3-1 on penalties, after the match finished 0–0 after 90 minutes. On 21 December 2008, United added more silverware to their trophy cabinet with a win in the 2008 FIFA Club World Cup Final, defeating the Ecuadorian side LDU Quito 1–0 in Japan, Wayne Rooney scoring the winning goal. Two months later, they added the 2009 League Cup to their trophy cabinet, after defeating Tottenham Hotspur 4-1 on penalties.[34] On 16 May, United secured their 11th Premier League title – and 18th league title overall – following a 0–0 draw at home to Arsenal, winning three consecutive Premier League titles for a second time.[35] On 27 May 2009, Barcelona beat Manchester United 2-0 in the Champions League final in Rome, falling to goals from Samuel Eto'o and Lionel Messi.[36]

Club crest and colours
Manchester United badge up to the most recent revision in 1998

During its days as Newton Heath, the club played in a number of different colours, the most recognisable being the yellow and green halved shirts worn from 1878 to 1892, and then again between 1894 and 1896; this strip was revived as an away kit in the early 1990s. Other kits worn by Newton Heath included a red and white quartered shirt (1892–1894) and a plain white shirt (1896–1902), both worn with blue shorts.[37] In 1902, in conjunction with the name change to Manchester United, the club changed their colours to red jerseys, white shorts and black socks, which has become the standard for most Man Utd home kits ever since. The most notable exception to this is the shirt that the team wore in the 1909 FA Cup Final against Bristol City, which was white with a red "V" sash.[38] This design was resurrected in the 1920s before United reverted back to the all-red shirts.

Away strips are usually white jerseys with black shorts and white socks, but other colours have been used, including a blue and white striped shirt used on-and-off from 1903 to 1916, an all-black kit in 1994 and 2003 and a navy blue shirt with silver horizontal pinstripes in 2000. One of the most famous, yet short-lived, United away kits, though, was the all grey kit from 1995–96. This kit was dropped after Manchester United failed to win a single game while wearing it. At half-time during a game against Southampton, when United were already 3–0 down, they switched to their blue and white third kit, but eventually lost 3–1. According to the players, the grey kit was not visible enough which led to the poor results.[39][40] Another famous Man Utd away kit included a reversible shirt that was white with black sleeves and gold trim on one side, and gold with black trim on the other side. This shirt was released as the last kit created by Umbro for the club before the change to Nike, and commemorated 100 years since the club had changed its name from Newton Heath to Manchester United.

The United third kit is traditionally all-blue in homage to the kit that the 1968 European Cup was won in. Exceptions to this rule have included a bright yellow kit worn in the early 1970s, the aforementioned blue and white striped shirt from 1996, which proved to be a firm favourite with the fans, and a white shirt with black and red horizontal pinstripes from 2004. United have also used what were originally used as training shirts as their third kit in the past, having adopted an all-black kit in the 1998–99 season and a dark blue shirt with maroon sides in 2001 for games against Southampton and PSV Eindhoven.

Currently, Manchester United's home jerseys are red with a vertical, white broken stripe with black trim on the reverse. The stripe is adorned with the letters MUFC at the top of the bottom portion, and a silhouette of the devil from the club badge at the top of the top portion. The AIG and Nike logos are also white. A patch with the words "The Red Devils" written in white, over an image of the club badge's devil, is attached to the bottom-left of the shirt. The club crest sits on a red shield of the same shape on the left breast. The away kit is white with blue piping around the side and back of the neck and down the sides of the body. The trim on the front of the neck is red. The letters "MUFC" are on the back of the collar and the club badge is located on a white shield over the left breast. The third shirt is royal blue, with sponsors' logos in white. Around the club badge, which sits on a blue shield, the words "May 29th 1968 40th Anniversary" are embroidered. Like the away shirt, the letters "MUFC" are on the back of the collar, while the inside of the collar is adorned with the coat of arms of the City of Manchester, in a design inspired by the tickets used for the 1968 European Cup Final.[41] The away and third shirts are worn with blue shorts.

The Manchester United crest has been altered on a few occasions, but the basic form remains similar. The badge is derived from the crest of the city of Manchester. The devil on the club badge stems from the club's nickname "The Red Devils", which was adopted in the early 1960s after Matt Busby heard it in reference to the red-shirted Salford rugby league side.[42] By the end of the 1960s, the devil had started to be included on club programmes and scarves, before it was finally incorporated into the club badge in 1970, holding its unmistakable trident. In 1998, the badge was once again redesigned, this time removing the words "Football Club
