Unidentified flying object

Studies and investigations into UFO reports conducted by governments (such as Project Blue Book in the United States and Project Condign in the United Kingdom), as well as by organisations and individuals have occurred over the years without confirmation of the fantastical claims of small but vocal groups of ufologists who favour unconventional or pseudoscientific hypotheses, often claiming that UFOs are evidence of extraterrestrial intelligence, technologically advanced cryptids, demons, interdimensional contact or future time travelers.

The U.S. government currently has two entities dedicated to UFO data collection and analysis: NASA's UAP independent study team and the All-domain Anomaly Resolution Office.

[24] As a bright comet that visits the inner solar system every 76 years, it was often identified as a unique isolated event in ancient historical documents whose authors were unaware that it was a repeating phenomenon.

However, as reported by historian Greg Eghanian, "a majority either had no idea what they could be or thought that witnesses were mistaken" while "visitors from space were not initially among the options that anyone had in mind, and Gallup didn't even mention if anyone surveyed brought up aliens.

Within weeks, reports of flying saucer sightings became a daily occurrence[53] with one particularly famous example being the Roswell incident in 1947 where remnants of a downed observation balloon were recovered by a farmer and confiscated by military personnel.

[55] A Trendex survey in August 1957, ten years after the Arnold incident, reported that over 25% of the U.S. public "believed unidentified flying objects could be from outer space".

[48] The cultural phenomenon showed up within some intellectual works such as the 1959 publication of Flying Saucers: A Modern Myth of Things Seen in the Sky by Carl Jung, a Swiss psychiatrist and psychoanalyst who founded analytical psychology.

Meanwhile, Leonard Nimoy narrated a popular occult and mystery TV series In Search of... while daytime talk shows of Mike Douglas, Merv Griffin, and Phil Donahue featured interviews with alien abductees and people who credulously reported stories about UFOs .

[66] Kloor writes that by the late 1990s, "other big UFO subthemes had been prominently introduced into pop culture, such as the abduction phenomenon and government conspiracy narrative, via best-selling books and, of course, The X-Files".

"[48] Interest was particularly fevered in the 1990s with the publicity surrounding the television broadcast of an Alien autopsy video marketed as "real footage" but later admitted to be a staged "re-enactment".

They all defended the "veracity of those claiming to have been kidnapped, examined, and experimented upon by beings from another world", writes Eghigian, as "new missionaries who simultaneously played the role of investigator, therapist, and advocate to their vulnerable charges".

This was followed closely by the publication of Loeb's book Extraterrestrial, in which he argued that the first interstellar comet ever observed, 'Oumuamua, might be an artificial light sail made by an alien civilization.

[80] In June 2021 a Pew research poll found that 51% in the United States thought that UFOs reported by people in the military were likely to be evidence of intelligent life from beyond the Earth.

[83] Historian Greg Eghigian wrote in August 2021 that "over the last fifty years, the mutual antagonism between paranormal believers and skeptics has largely framed discussion about unidentified flying objects" and that "it often gets personal" with those taking seriously the prospect that UFOs are extraterrestrial in origin dismissing those who consider UFOs to be worth studying as "narrow-minded, biased, obstinate, and cruel" while the skeptics brushed off "devotees" as "naïve, ignorant, gullible, and downright dangerous".

Eghigian points out our current "stark divide did not happen overnight, and its roots lie in the postwar decades, in a series of events that—with their news coverage, grainy images, celebrity crusaders, exasperated skeptics, unsatisfying military statements, and accusations of a government cover-up—foreshadow our present moment".

Horton observes that these "alien movies have generally reflected shifting cultural anxieties, from the existential terror of nuclear war to foreign enslavement to loss of bodily control".

They were characterized by "extreme rates of climb [and] maneuverability", general lack of noise, absence of a trail, occasional formation flying, and "evasive" behavior "when sighted or contacted by friendly aircraft and radar", suggesting a controlled craft.

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.

When word of the curriculum became public, in 1970, the Air Force issued a statement to the effect that the book was outdated and cadets instead were being informed of the Condon Report's negative conclusion.

In 1947, Brigadier General George F. Schulgen of Army Air Corps Intelligence, warned "the first reported sightings might have been by individuals of Communist sympathies with the view to causing hysteria and fear of a secret Russian weapon.

They add they can neither prove nor disprove the Extraterrestrial Hypothesis (ETH), but their Steering Committee's clear position is that they cannot discard the possibility that some fraction of the very strange 22% of unexplained cases might be due to distant and advanced civilizations.

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 resulting report, titled "Unidentified Aerial Phenomena in the UK Defence Region", was publicly released in 2006, but the identity and credentials of whoever constituted Project Condign remains classified.

"[135] 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."

The MoD said there was no value in continuing to receive and investigate sightings in a release, stating that "in over fifty years, no UFO report has revealed any evidence of a potential threat to the United Kingdom.

Novella says that instead of accepting the null hypothesis, UFO enthusiasts tend to engage in special pleading by offering outlandish, untested explanations for the validity of the ETH, which violate Occam's razor.

[190] In May 2019, The New York Times reported that American Navy fighter jets had several instances of unidentified instrumentation and tracking data while conducting exercises off the eastern seaboard of the United States from the summer of 2014 to March 2015.

[198][199] Science writer and skeptic Mick West suggested the image was the result of an optical effect called a bokeh which can make out of focus light sources appear triangular or pyramidal due to the shape of the aperture of some lenses.

[210] 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.

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.
