Ufo

"UFO" redirects here. For other uses, see UFO (disambiguation).

An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky (or near or on the ground, but observed hovering, landing, or departing into the sky) that is not readily identifiable as any known object or phenomenon by visual observation and/or use of associated instrumentation such as radar. These anomalies were referred to popularly as "flying saucers" or "flying discs" during the late 1940s and early 1950s.

The term "UFO" (or "UFOB") was officially created in 1953 by the United States Air Force (USAF) to replace the more popular terms because of the variety of shapes described other than "discs" or "saucers." It was stated that a "UFOB" was "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." As originally defined, the term was restricted to those fraction of cases which remained unidentified after investigation, with USAF interest being for potential national security reasons and/or "technical aspects." (See Air Force Regulation 200-2.) The term UFO became more widespread during the 1950s, at first in professional literature, but later in popular use. UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security.

Various studies, both governmental and civilian, have reached varying conclusions, some saying that the phenomenon does not represent a threat to national security nor does it contain anything worthy of scientific pursuit (e.g., 1953 CIA Robertson Panel, USAF Project Blue Book, Condon Committee), while others have reached the opposite conclusions (see, e.g., 1999 French COMETA study, 1948 USAF Estimate of the Situation, Sturrock panel). A number of military personnel and others have given statements about having witnessed UFOs themselves or having been privy to information about them. Culturally, the phenomenon has often been associated with extraterrestrial life or government-related conspiracy theories, and has become a popular theme in fiction.

Terminology

The Oxford English Dictionary defines a UFO as "An unidentified flying object; a 'flying saucer'." The first published book to use the word was authored by Donald E. Keyhoe.[1]

The acronym "UFO" was coined by Captain Edward J. Ruppelt, who headed Project Blue Book, then the USAF's official investigation of UFOs. He wrote, "Obviously the term 'flying saucer' is misleading when applied to objects of every conceivable shape and performance. For this reason the military prefers the more general, if less colorful, name: unidentified flying objects. UFO (pronounced Yoo-foe) for short."[2] Other phrases that were used officially and that predate the UFO acronym include "flying flapjack," "flying disc," "unexplained flying discs," "unidentifiable object," and "flying saucer."[3][4][5]

The phrase "flying saucer" had gained widespread attention after the summer of 1947. On June 24, a civilian pilot named Kenneth Arnold reported seeing nine objects flying in formation near Mount Rainier. Arnold timed the sighting and estimated the speed of discs to be over 1,200 mph (1,931 km/h). At the time, he described the objects' shape as being somewhat disc-like or saucer-like, leading to newspaper accounts of "flying saucers" and "flying discs." (For details, see Kenneth Arnold UFO sighting.)

In popular usage the term UFO came to be used to refer to alien spacecraft.[1] and because of the public and media ridicule associated with the topic, some investigators prefer to use such terms as unidentified aerial phenomenon (or UAP) or anomalous phenomena, as in the title of the National Aviation Reporting Center on Anomalous Phenomena (NARCAP).[6]

Studies

Studies have established that the majority of UFO observations are misidentified conventional objects or natural phenomena—most commonly aircraft, balloons, noctilucent clouds, nacreous clouds, or astronomical objects such as meteors or bright planets with a small percentage even being hoaxes.[note 1] After excluding incorrect reports, however, most investigators have acknowledged that between 5% and 20% of reported sightings remain unexplained, and therefore can be classified as unidentified in the strictest sense. Many reports have been made by such trained observers as pilots, police, and the military; some have involved simultaneous radar tracking and visual accounts.[7] Proponents of the extraterrestrial hypothesis (ETH) suggest that these unexplained reports are of alien spacecraft, though various other hypotheses have been proposed.

While UFOs have been the subject of extensive investigation by various governments and although some scientists support the extraterrestrial hypothesis, few scientific papers about UFOs have been published in peer-reviewed journals.[8] There has been some debate in the scientific community about whether any scientific investigation into UFO sightings is warranted.[9][10][11][12][13][14][15]

The void left by the lack of institutional scientific study has given rise to independent researchers and groups, including the National Investigations Committee on Aerial Phenomena (NICAP) in the mid-20th century and, more recently, the Mutual UFO Network (MUFON)[16] and the Center for UFO Studies (CUFOS).[17] The term "Ufology" is used to describe the collective efforts of those who study reports and associated evidence of unidentified flying objects. According to MUFON, as of 2011 the number of UFO reports to their worldwide offices has increased by 67% from the previous three years and now averages around 500 reported sightings per month.[18]

UFOs have become a relevant theme in modern culture,[19] and the social phenomena have been the subject of academic research in sociology and psychology.[8]

Early 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 BC and possibly as early as 467 BC. Such sightings throughout history often were treated as supernatural portents, angels, or other religious omens. Some current-day UFO researchers have noticed similarities between some religious symbols in medieval paintings and UFO reports[20] though the canonical and symbolic character of such images is documented by art historians placing more conventional religious interpretations on such images.[21]

  • On January 25, 1878, the Denison Daily News noted that John Martin, a local farmer, had reported seeing a large, dark, circular object resembling a balloon flying "at wonderful speed." Martin, according to the newspaper account, said it appeared to be about the size of a saucer, the first known use of the word "saucer" in association with a UFO.[22]
  • In April 1897 thousands of people reported seeing "airships" in various parts of the United States. Many signed affidavits. Scores of people even reported talking to the pilots. Thomas Edison was asked his opinion, and said, "You can take it from me that it is a pure fake."[23][24]
  • On February 28, 1904, there was a sighting by three crew members on the USS Supply 300 miles (483 km) west of San Francisco, reported by Lieutenant 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, he said.[25][26][27][28]
  • The three earliest known pilot UFO sightings, of 1,305 similar sitings cataloged by NARCAP, took place in 1916 and 1926. On January 31, 1916, a UK pilot near Rochford reported a row of lights, resembling 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 said he had been forced to land by a huge, wingless, cylindrical object.[29]
  • On August 5, 1926, while traveling in the Humboldt Mountains of Tibet's Kokonor region, Russian explorer Nicholas Roerich reported, 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."[30] Another description by Roerich was of 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."[31]
  • 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 weapons.[32][33]
  • 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 were 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 General George C. Marshall and Secretary of War Henry L. Stimson insisted that real aircraft were involved. The incident later became known as the Battle of Los Angeles, or the West coast air raid.
  • In 1946 more than 2,000 reports were collected, primarily by the Swedish military, of unidentified aerial objects over the Scandinavian nations, along with isolated reports from France, Portugal, Italy and Greece. The objects were referred to as "Russian hail" and later as "ghost rockets" because it was thought that the mysterious objects were possibly Russian tests of captured German V1 or V2 rockets. Although most were thought to be such natural phenomena as meteors, more than 200 were tracked on radar by the Swedish military and deemed to be "real physical objects." In a 1948 top secret document, Swedish authorities advised the USAF Europe that some of their investigators believed these craft to be extraterrestrial in origin.[34]

Investigations

UFOs have been subject to investigations over the years that varied widely in scope and scientific rigor. Governments or independent academics in the United States, Canada, the United Kingdom, Japan, Peru, 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 USAF 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 No. 14[35] by the Battelle Memorial Institute, and the Brazilian Air Force's 1977 Operação Prato (Operation Saucer). France has had an ongoing investigation (GEPAN/SEPRA/GEIPAN) within its space agency Centre national d'études spatiales (CNES) since 1977; the government of Uruguay has had a similar investigation since 1989.

Project Sign

Main article: Project Sign

Project Sign in 1948 produced a highly classified finding (see Estimate of the Situation) that the best UFO reports probably had an extraterrestrial explanation; the private but high-level French COMETA study of 1999 reached a similar conclusion. A top secret Swedish military opinion given to the USAF in 1948 stated that some of their analysts believed that the 1946 ghost rockets and later flying saucers had extraterrestrial origins. (For document, see Ghost rockets.) In 1954 German rocket scientist Hermann Oberth revealed that an internal West German government investigation, which he headed, had arrived at an extraterrestrial conclusion, but this study was never made public.

Project Magnet

Main article: Project Magnet

Classified, internal reports by the Canadian Project Magnet in 1952 and 1953 also assigned high probability to extraterrestrial origins. Publicly, however, neither Project Magnet nor later Canadian defense studies ever stated such a conclusion.

Project Grudge

Main article: Project Grudge

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 Committee's negative conclusion as a rationale, thus ending official Air Force UFO investigations. However, a 1969 USAF document, known as the Bolender memo, along with later government documents, revealed that non-public U.S. government UFO investigations continued after 1970. The Bolender 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 already were handled outside 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."[note 2] In addition, in the late 1960s a chapter on UFOs in the Space Sciences course at the U.S. Air Force Academy gave serious consideration to possible extraterrestrial origins. When word of the curriculum became public, the Air Force in 1970 issued a statement to the effect that the book was outdated and that cadets instead were being informed of the Condon Report's negative conclusion.[36]

USAF Regulation 200-2

Air Force Regulation 200-2,[37] 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." The regulation went on to say that "it is permissible to inform news media representatives on UFOB's when the object is positively identified as a familiar object," but added: "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."[37]

Project Blue Book

Main article: Project Blue Book

J. Allen Hynek, a trained astronomer who served as a scientific advisor for Project Blue Book, was initially skeptical of UFO reports, but eventually came to the conclusion that many of them could not be satisfactorily explained and was highly critical of what he described as "the cavalier disregard by Project Blue Book of the principles of scientific investigation."[38] Leaving government work, he founded the privately funded CUFOS, to whose work he devoted the rest of his life. Other private groups studying the phenomenon include the MUFON, a grass roots organization whose investigator's handbooks go into great detail on the documentation of alleged UFO sightings.

Like Hynek, Jacques Vallée, a scientist and prominent UFO researcher, has pointed to what he believes is the scientific deficiency of most UFO research, including government studies. He complains of the mythology and cultism often associated with the phenomenon, but alleges that several hundred professional scientists—a group both he and Hynek have termed "the invisible college"—continue to study UFOs in private.[19]

Scientific studies

The study of UFOs has received little support in mainstream scientific literature. Official studies ended in the U.S. in December 1969, following the statement by the government scientist Edward Condon that further study of UFOs could not be justified on grounds of scientific advancement.[11][39] The Condon Report and its conclusions were endorsed by the National Academy of Scientists, of which Condon was a member. On the other hand, a scientific review by the UFO subcommittee of the American Institute of Aeronautics and Astronautics (AIAA) disagreed with Condon's conclusion, noting that at least 30 percent of the cases studied remained unexplained and that scientific benefit might be gained by continued study.

Critics argue that all UFO evidence is anecdotal[40] and can be explained as prosaic natural phenomena. Defenders of UFO research counter that knowledge of observational data, other than what is reported in the popular media, is limited in the scientific community and that further study is needed.[19][41]

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

Some public government reports have acknowledged the possibility of physical reality of UFOs, but have stopped short of proposing extraterrestrial origins, though not dismissing the possibility entirely. Examples are the Belgian military investigation into large triangles over their airspace in 1989–1991 and the 2009 Uruguayan Air Force study conclusion (see below).

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

United States

U.S. investigations into UFOs include:

  • The Interplanetary Phenomenon Unit (IPU), established by the U.S. Army sometime in the 1940s, and about which little is known. In 1987, British UFO researcher Timothy Good received from the Army's director of counter-intelligence a letter confirming the existence of the IPU. The letter stated that "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.[42]
  • Project Blue Book, previously Project Sign and Project Grudge, conducted by the USAF 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, UK, U.S., and Greek militaries (1946–1947)
  • The secret CIA Office of Scientific Investigation (OS/I) study (1952–53)
  • 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)[43]
  • The private Sturrock panel (1998)

Thousands of documents released under FOIA also indicate that many U.S. intelligence agencies collected (and still collect) information on UFOs. These agencies include the Defense Intelligence Agency (DIA), FBI,[5] CIA, National Security Agency (NSA), as well as military intelligence agencies of the Army and U.S. Navy, in addition to the Air Force.[note 3]

The investigation of UFOs has also attracted many civilians, who in the U.S formed research groups such as NICAP (active 1956–1980), Aerial Phenomena Research Organization (APRO) (active 1952–1988), MUFON (active 1969–), and CUFOS (active 1973–).

In November 2011, the White House released an official response to two petitions asking the U.S. government to acknowledge formally that aliens have visited this planet and to disclose any intentional withholding of government interactions with extraterrestrial beings. According to the response, "The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race."[44][45] Also, according to the response, there is "no credible information to suggest that any evidence is being hidden from the public's eye."[44][45] The response further noted that efforts, like SETI and NASA's Kepler space telescope and Mars Science Laboratory, continue looking for signs of life. The response noted "odds are pretty high" that there may be life on other planets but "the odds of us making contact with any of them—especially any intelligent ones—are extremely small, given the distances involved."[44][45]

Post-1947 sightings

Following the large U.S. surge in sightings in June and early July 1947, on July 9, 1947, United States Army Air Forces (USAAF) intelligence, in cooperation with the FBI,[5] began a formal investigation into selected sightings with characteristics that could not be immediately rationalized, which included Kenneth Arnold's and that of the United Airlines crew. The USAAF used "all of its top scientists" to determine whether "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."[46] 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."[47]

A further review by the intelligence and technical divisions of the Air Materiel Command at Wright Field reached the same conclusion. It reported 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 therefore 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.[note 4]

Project Sign

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, but 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 J. Allen Hynek and Capt. Edward J. Ruppelt, the first head of the USAF's Project Blue Book.[48]

Another highly classified U.S. study was conducted by the CIA's Office of Scientific Investigation (OS/I) in the latter half of 1952 in response to orders from the National Security Council (NSC). This study concluded UFOs were real physical objects of potential threat to national security. One OS/I memo to the CIA Director (DCI) in December read:
the reports of incidents convince us that there is something going on that must have immediate attention ... Sightings of unexplained objects at great altitudes and traveling at high speeds in the vicinity of major U.S. defense installations are of such a nature that they are not attributable to natural phenomena or any known types of aerial vehicles.
The matter was considered so urgent that OS/I drafted a memorandum from the DCI to the NSC proposing that the NSC establish an investigation of UFOs as a priority project throughout the intelligence and the defense research and development community. It also urged the DCI to establish an external research project of top-level scientists, now known as the Robertson Panel to analyze the problem of UFOs. The OS/I investigation was called off after the Robertson Panel's negative conclusions in January 1953.[49]

The Condon Committee

Main article: Condon Committee

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 U.S. government's official investigation of UFOs, though various government intelligence agencies continue unofficially to investigate or monitor the situation.[note 5]

Controversy has surrounded the Condon Report, both before and after it was released. It has been observed that the report was "harshly criticized by numerous scientists, particularly at the powerful AIAA ... [which] recommended moderate, but continuous scientific work on UFOs."[11] In an address to the AAAS, James E. McDonald stated that he believed science had failed to mount adequate studies of the problem and criticized the Condon Report and earlier studies by the USAF as scientifically deficient. He also questioned the basis for Condon's conclusions[50] and argued that the reports of UFOs have been "laughed out of scientific court."[10] J. Allen Hynek, an astronomer who worked as a USAF consultant from 1948, sharply criticized the Condon Committee Report and later wrote two nontechnical books that set forth the case for continuing to investigate UFO reports.

Ruppelt recounted his experiences with Project Blue Book, a USAF investigation that preceded Condon's.[51]

Notable cases

Canada

In Canada, the Department of National Defence has dealt with reports, sightings and investigations of UFOs across Canada. In addition to conducting investigations into crop circles in Duhamel, Alberta, it still considers "unsolved" the Falcon Lake incident in Manitoba and the Shag Harbour UFO incident in Nova Scotia.[52]

Early Canadian studies included Project Magnet (1950–1954) and Project Second Storey (1952–1954), supported by the Defence Research Board. These studies were headed by Canadian Department of Transport radio engineer Wilbert B. Smith, who later publicly supported extraterrestrial origins.

In the Shag Harbour UFO incident, a large object sequentially flashing lights was seen and heard to dive into the water by multiple witnesses. The Royal Canadian Mounted Police and many local residents also witnessed a light floating on the water immediately afterward, and a large patch of unusual yellow foam when a water search was initiated. Multiple government agencies were eventually involved in trying to identify the crashed object and searching for it. Canadian naval divers later purportedly found no wreckage. In official documents, the object was called a "UFO" because no conventional explanation for the crashed object was discovered. Around the same time, both the Canadian and U.S. military were involved in another UFO-related search at Shelburne, Nova Scotia, approximately 30 miles (48 km) from Shag Harbour.

France

On March 2007, the French space agency CNES published an archive of UFO sightings and other phenomena online.[53]

French studies include GEPAN/SEPRA/GEIPAN (1977–), within CNES, the longest ongoing government-sponsored investigation. About 14% of some 6,000 cases studied remained unexplained. The official opinion of GEPAN/SEPRA/GEIPAN has been neutral or negative, but the three heads of the studies have gone on record in stating that UFOs were real physical flying machines beyond our knowledge or that the best explanation for the most inexplicable cases was an extraterrestrial one.[54][55][56]

The French COMETA panel (1996–1999) was a private study undertaken mostly by aerospace scientists and engineers affiliated with CNES and high-level French Air Force military intelligence analysts, with ultimate distribution of their study intended for high government officials. The COMETA panel likewise concluded the best explanation for the inexplicable cases was the extraterrestrial hypothesis and went further in accusing the United States government of a massive cover-up.[57][58][59][60]

The most notable cases of UFO sightings in France include the Valensole UFO incident in 1965, and the Trans-en-Provence Case in 1981.

Italy

According to some Italian ufologists, the first documented case of a UFO in Italy dates back to April 11, 1933, to Varese. Documents of the time show that an alleged UFO crashed or landed near Vergiate. Following this, Benito Mussolini created a secret group to look at it.[61][62]

Alleged UFO sightings gradually increased since the war, peaking in 1978 and 2005. Notable cases include:

  • In 1978, there has been also the story of Pier Fortunato Zanfretta, the best known and most controversial case of an Italian alleged alien abduction. Zanfretta said to have been kidnapped on the night of 6 December and 7 December while he was performing his job at Marzano, in the municipality of Torriglia in the Province of Genoa.[67]

United Kingdom

The UK's Flying Saucer Working Party published its final report in June 1951, which remained secret for over 50 years. The Working Party concluded that all UFO sightings could be explained as misidentifications of ordinary objects or phenomena, optical illusions, psychological misperceptions/aberrations, or hoaxes. The report stated: "We accordingly recommend very strongly that no further investigation of reported mysterious aerial phenomena be undertaken, unless and until some material evidence becomes available."[68]

Eight file collections on UFO sightings, dating from 1978 to 1987, were first released on May 14, 2008, to The National Archives by the Ministry of Defence (MoD).[69] Although kept secret from the public for many years, most of the files have low levels of classification and none are classified Top Secret. 200 files are set to be made public by 2012. The files are correspondence from the public sent to the British government and officials, such as the MoD and Margaret Thatcher. The MoD released the files under the Freedom of Information Act due to requests from researchers.[70] These files include, but are not limited to, UFOs over Liverpool and the Waterloo Bridge in London.[71]

On October 20, 2008, more UFO files were released. One case released detailed that in 1991 an Alitalia passenger aircraft was approaching London Heathrow Airport when the pilots saw what they described as a "cruise missile" fly extremely close to the cockpit. The pilots believed that a collision was imminent. UFO expert David Clarke says that this is one of the most convincing cases for a UFO he has come across.[72]

A secret study of UFOs was undertaken for the Ministry of Defence between 1996 and 2000 and was code-named Project Condign. The resulting report, titled "Unidentified Aerial Phenomena in the UK Defence Region," was publicly released in 2006, but the identity and credentials of whomever constituted Project Condign remains classified. The report confirmed earlier findings that the main causes of UFO sightings are misidentification of man-made and natural objects. The report noted: "No artefacts of unknown or unexplained origin have been reported or handed to the UK authorities, despite thousands of Unidentified Aerial Phenomena reports. There are no SIGINT, ELINT or radiation measurements and little useful video or still IMINT." It concluded: "There is no evidence that any UAP, seen in the UKADR [UK Air Defence Region], are incursions by air-objects of any intelligent (extraterrestrial or foreign) origin, or that they represent any hostile intent." A little-discussed conclusion of the report was that novel meteorological plasma phenomenon akin to ball lightning are responsible for "the majority, if not all" of otherwise inexplicable sightings, especially reports of black triangle UFOs.[73]

On December 1, 2009, the Ministry of Defence quietly closed down its UFO investigations unit. The unit's hotline and email address were suspended by the MoD on that date. The MoD said there was no value in continuing to receive and investigate sightings in a release, stating
in over fifty years, no UFO report has revealed any evidence of a potential threat to the United Kingdom. The MoD has no specific capability for identifying the nature of such sightings. There is no Defence benefit in such investigation and it would be an inappropriate use of defence resources. Furthermore, responding to reported UFO sightings diverts MoD resources from tasks that are relevant to Defence."

The Guardian reported that the MoD claimed the closure would save the Ministry around £50,000 a year. The MoD said that it would continue to release UFO files to the public through The National Archives.[74]

Notable cases

  • According to records released on August 5, 2010, British wartime prime minister Winston Churchill banned the reporting for 50 years of an alleged UFO incident because of fears it could create mass panic. Reports given to Churchill asserted that the incident involved an Royal Air Force (RAF) reconnaissance plane returning from a mission in France or Germany toward the end of the Second World War. It was over or near the English coastline when it was allegedly intercepted by a strange metallic object that matched the aircraft's course and speed for a time before accelerating away and disappearing. The plane's crew were reported to have photographed the object, which they said had "hovered noiselessly" near the aircraft, before moving off.[75] According to the documents, details of the coverup emerged when a man wrote the government in 1999 seeking to find out more about the incident and described how his grandfather, who had served with the RAF in the Second World War, was present when Churchill and U.S. General Dwight D. Eisenhower discussed how to deal with the UFO encounter.[76][77] The files come from more than 5,000 pages of UFO reports, letters and drawings from members of the public, as well as questions raised in Parliament. They are available to download from The National Archives website.[69]
  • In the April 1957 West Freugh incident in Scotland, named after the principal military base involved, two unidentified objects flying high over the UK were tracked by radar operators. The objects were reported to operate at speeds and perform maneuvers beyond the capability of any known craft. Also significant is their alleged size, which – based on the radar returns – was closer to that of a ship than an aircraft.
  • In the Rendlesham Forest incident of December 1980, U.S. military personnel witnessed UFOs near the air base at Woodbridge, Suffolk, over a period of three nights. On one night the deputy base commander, Colonel Charles I. Halt, and other personnel followed one or more UFOs that were moving in and above the forest for several hours. Col. Halt made an audio recording while this was happening and subsequently wrote an official memorandum summarizing the incident. After retirement from the military, he said that he had deliberately downplayed the event (officially termed 'Unexplained Lights') to avoid damaging his career. Other base personnel are said to have observed one of the UFOs, which had landed in the forest, and even gone up to and touched it.

Uruguay

The Uruguayan Air Force has been conducting an ongoing UFO investigation since 1989 and analyzed 2,100 cases, of which they regard only 40 (about 2%) as definitely lacking any conventional explanation. All files have recently been declassified. The unexplained cases include military jet interceptions, abductions, cattle mutilations, and physical landing trace evidence. Colonel Ariel Sanchez, who currently heads the investigation, summarized its findings as follows:
The commission managed to determine modifications to the chemical composition of the soil where landings are reported. The phenomenon exists. It could be a phenomenon that occurs in the lower sectors of the atmosphere, the landing of aircraft from a foreign air force, up to the extraterrestrial hypothesis. It could be a monitoring probe from outer space, much in the same way that we send probes to explore distant worlds. The UFO phenomenon exists in the country. I must stress that the Air Force does not dismiss an extraterrestrial hypothesis based on our scientific analysis.[78]

Astronomer reports

The USAF's Project Blue Book files indicate that approximately 1%[79] of all unknown reports came from amateur and professional astronomers or other users of telescopes (such as missile trackers or surveyors). In 1952, astronomer J. Allen Hynek, then a consultant to Blue Book, conducted a small survey of 45 fellow professional astronomers. Five reported UFO sightings (about 11%). In the 1970s, astrophysicist Peter A. Sturrock conducted two large surveys of the AIAA and American Astronomical Society (AAS). About 5% of the members polled indicated that they had had UFO sightings.

Astronomer Clyde Tombaugh, who admitted to six UFO sightings, including three green fireballs, supported the Extraterrestrial hypothesis for UFOs and stated he thought scientists who dismissed it without study were being "unscientific." Another astronomer was Lincoln LaPaz, who had headed the Air Force's investigation into the green fireballs and other UFO phenomena in New Mexico. LaPaz reported two personal sightings, one of a green fireball, the other of an anomalous disc-like object. (Both Tombaugh and LaPaz were part of Hynek's 1952 survey.) Hynek himself took two photos through the window of a commercial airliner of a disc-like object that seemed to pace his aircraft.[80]

In 1980, a survey of 1800 members of various amateur astronomer associations by Gert Helb and Hynek for CUFOS found that 24% responded "yes" to the question "Have you ever observed an object which resisted your most exhaustive efforts at identification?"[81]

Decline

Since the advent of the Internet and the mass availability of cameras in cell phones, UFO sightings have dramatically declined. According to the Association for the Scientific Study of Anomalous Phenomena (ASSAP), sightings have declined by 96% since 1988.[82] Dave Wood, the chairman of ASSAP, said “It is certainly a possibility that in ten years time, it will be a dead subject," citing not only the decline in sightings, but also a decline in popular interest and obsession within the community with conspiracy theories and old cases.

Identification of UFOs


Studies show that after careful investigation, the majority of UFOs can be identified as ordinary objects or phenomena . The most commonly found identified sources of UFO reports are:

A 1952–1955 study by the Battelle Memorial Institute for the USAF included these categories as well as a "psychological" one. However, the scientific analysts were unable to come up with prosaic explanations for 22% of the 3,200 cases they examined and 33% of what were considered the best cases remained unexplained, double the number of the worst cases. (For the full statistical breakdown, see Identification studies of UFOs.) Of the 69% identifieds, 38% were deemed definitely explained while 31% were thought to be "questionable." About 9% of the cases were considered to have insufficient information to make a determination.

The official French government UFO investigation (GEPAN/SEPRA/GEIPAN), run within CNES between 1977 and 2004, scientifically investigated about 6,000 cases and found that 14% defied any rational explanation, 46% were deemed definitely or likely identifiable, while 41% lacked sufficient information for classification.

An individual 1979 study by CUFOS researcher Allan Hendry found, as did other investigations, that only a small percentage of cases he investigated were hoaxes (<1 %) and that most sightings were actually honest misidentifications of prosaic phenomena. Hendry attributed most of these to inexperience or misperception.[84] However, Hendry's figure for unidentified cases was considerably lower than many other UFO studies such as Project Blue Book or the Condon Report that have found rates of unidentified cases ranging from 6% to 30%. Hendry found that 89% of the cases he studied had a clear prosaic explanation, and he discarded a further 3% due to unreliable or contradictory witnesses or insufficient information. The remaining 9% of reports could not definitively be explained by prosaic phenomena, although he felt that a further 7% could possibly be explained, leaving only the very best 1.5% without plausible explanation.

Claims by military, government, and aviation personnel

Since 2001 there have been calls for greater openness on the part of the government by various persons. In May 2001, a press conference was held at the National Press Club in Washington, D.C., by an organization called the Disclosure Project, featuring twenty persons including retired Air Force and FAA personnel, intelligence officers and an air traffic controller.[85][86][87] [88] [89] [90] [91] They all gave a brief account of what they knew or had witnessed, and stated that they would be willing to testify to what they had said under oath to a Congressional committee. According to a 2002 report in the Oregon Daily Emerald, Disclosure Project founder Steven M. Greer has gathered 120 hours of testimony from various government officials on the topic of UFO's, including astronaut Gordon Cooper and a Brigadier General.[92]

In 2007, former Arizona governor Fife Symington came forward and admitted that he had seen "a massive, delta-shaped craft silently navigate over Squaw Peak, a mountain range in Phoenix, Arizona" in 1997.[93]

On September 27, 2010, a group of six former USAF officers and one former enlisted Air Force man held a press conference at the National Press Club in Washington, D.C., on the theme "U.S. Nuclear Weapons Have Been Compromised by Unidentified Aerial Objects."[94] They told how they had witnessed UFOs hovering near missile sites and even disarming the missiles.

From April 29 to May 3, 2013, the Paradigm Research Group held the "Citizen Hearing on Disclosure" at the National Press Club. The group paid former U.S. Senator Mike Gravel and former Representatives Carolyn Cheeks Kilpatrick, Roscoe Bartlett, Merrill Cook, Darlene Hooley, and Lynn Woolsey $20,000 each to hear testimony from a panel of researchers which included witnesses from military, agency, and political backgrounds.[95][96]

Extraterrestrial hypothesis

While technically a UFO refers to any unidentified flying object, in modern popular culture the term UFO has generally become synonymous with alien spacecraft;[97] however, the term ETV (ExtraTerrestrial Vehicle) is sometimes used to separate this explanation of UFOs from totally earthbound explanations.[98]

Proponents argue that because these objects appear to be technological and not natural phenomena and are alleged to display flight characteristics or have shapes seemingly unknown to conventional technology, the conclusion is that they must not be from Earth.

Associated claims

Besides anecdotal visual sightings, reports sometimes include claims of other kinds of evidence, including cases studied by the military and various government agencies of different countries (such as Project Blue Book, the Condon Committee, the French GEPAN/SEPRA, and Uruguay's current Air Force study).

A comprehensive scientific review of cases where physical evidence was available was carried out by the 1998 Sturrock panel, with specific examples of many of the categories listed below.[104][105][106]

  • Radar contact and tracking, sometimes from multiple sites. These have included military personnel and control tower operators, simultaneous visual sightings, and aircraft intercepts. One such example were the mass sightings of large, silent, low-flying black triangles in 1989 and 1990 over Belgium, tracked by NATO radar and jet interceptors, and investigated by Belgium's military (included photographic evidence).[107] Another famous case from 1986 was the Japan Air Lines flight 1628 incident over Alaska investigated by the Federal Aviation Administration (FAA).
  • Photographic evidence, including still photos, movie film, and video.
  • Claims of physical trace of landing UFOs, including ground impressions, burned and/or desiccated soil, burned and broken foliage, magnetic anomalies[specify], increased radiation levels, and metallic traces. (See, e. g. Height 611 UFO incident or the 1964 Lonnie Zamora's Socorro, New Mexico encounter of the USAF Project Blue Book cases.) A well-known example from December 1980 was the USAF Rendlesham Forest incident in England. Another occurred in January 1981 in Trans-en-Provence and was investigated by GEPAN, then France's official government UFO-investigation agency. Project Blue Book head Edward J. Ruppelt described a classic 1952 CE2 case involving a patch of charred grass roots.
  • Physiological effects on people and animals including temporary paralysis, skin burns and rashes, corneal burns, and symptoms superficially resembling radiation poisoning, such as the Cash-Landrum incident in 1980.
  • Animal/cattle mutilation cases, that some feel are also part of the UFO phenomenon.
  • Biological effects on plants such as increased or decreased growth, germination effects on seeds, and blown-out stem nodes (usually associated with physical trace cases or crop circles)
  • Electromagnetic interference (EM) effects. A famous 1976 military case over Tehran, recorded in CIA and DIA classified documents, was associated with communication losses in multiple aircraft and weapons system failure in an F-4 Phantom II jet interceptor as it was about to fire a missile on one of the UFOs.[108]
  • Apparent remote radiation detection, some noted in FBI and CIA documents occurring over government nuclear installations at Los Alamos National Laboratory and Oak Ridge National Laboratory in 1950, also reported by Project Blue Book director Edward J. Ruppelt in his book.
  • Claimed artifacts of UFOs themselves, such as 1957, Ubatuba, Brazil, magnesium fragments analyzed by the Brazilian government and in the Condon Report and by others. The 1964 Lonnie Zamora incident also left metal traces, analyzed by NASA.[109][110] A more recent example involves a tear drop-shaped object recovered by Bob White and was featured in a television episode of UFO Hunters.[111]
  • Angel hair and angel grass, possibly explained in some cases as nests from ballooning spiders or chaff.

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, NACA/NASA engineer Paul R. Hill in his book Unconventional Flying Objects, and German rocketry pioneer Hermann Oberth. 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.[note 6]

Categorization

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.
  • 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 1977 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.

Scientific skepticism

A scientifically skeptical group that has for many years offered critical analysis of UFO claims is the Committee for Skeptical Inquiry (CSI).

Responding to local beliefs that "extraterrestrial beings" in UFOs were responsible for crop circles appearing in Indonesia, the government and the National Institute of Aeronautics and Space (LAPAN) described them as "man-made." Thomas Djamaluddin, research professor of astronomy and astrophysics at Lapan stated: "We have come to agree that this 'thing' cannot be scientifically proven. Scientists have put UFOs in the category of pseudoscience."[112]

Conspiracy theories

UFOs are sometimes an element of conspiracy theories in which governments are allegedly intentionally "covering up" the existence of aliens by removing physical evidence of their presence, or even collaborating with extraterrestrial beings. 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.[113][114] 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 French COMETA study by various French generals and aerospace experts, and Yves Sillard (former director of CNES, new director of French UFO research organization GEIPAN).[53]

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.)

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 1,000 pages, and some estimate that further undiscovered documents may total nearly 4000 pages. A José Luis Jordan Pena came forward in the early 1990s claiming responsibility for the phenomenon, and most consider there to be little reason to challenge his claims.[115]
  • 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 the Soviet lunar probe Luna 3 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.
  • Ed Walters, a building contractor, in 1987 allegedly perpetrated a hoax in Gulf Breeze, Florida. Walters claimed at first having seen a small UFO flying near his home and took some photographs of the craft. Walters reported and documented a series of UFO sightings over a period of three weeks and took several photographs. These sightings became famous and were called Gulf Breeze UFO incident. 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. Most investigators like the forensic photo expert William G. Hyzer[116] now consider the sightings to be a hoax.
  • Warren William "Billy" Smith is a popular writer and confessed hoaxster.[117]

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 U.S. President Gerald Ford in a 1977 poll taken just nine months after he left the White House.[118][119] A 1996 Gallup Poll reported that 71 percent of the United States population believed that the U.S. government was covering up information regarding UFOs. A 2002 Roper Poll for the Sci-Fi Channel found similar results, but with more people believing that UFOs are 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. In the film Yellow Submarine, Ringo states that the yellow submarine that is following him "must be one of them unidentified flying cupcakes."[120][121] Another effect of the flying saucer type of UFO sightings has been Earth-made flying saucer craft in space fiction, for example the United Planets Cruiser C57D in Forbidden Planet (1956), the Jupiter 2 in Lost in Space, and the saucer section of the USS Enterprise in Star Trek, and many others.

UFOs and extraterrestrials have been featured in many movies.
