This is a list of notable people who are ufologists (people who investigate whether UFOs are linked to extraterrestrial aliens).
An unidentified flying object (UFO), or unidentified anomalous phenomenon (UAP), is any perceived airborne, submerged or transmedium phenomenon that cannot be immediately identified or explained. Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.
UFO conspiracy theories are a subset of conspiracy theories which argue that various governments and politicians globally, in particular the United States government, are suppressing evidence that unidentified flying objects are controlled by a non-human intelligence or built using alien technology. Such conspiracy theories usually argue that Earth governments are in communication or cooperation with extraterrestrial visitors despite public disclaimers, and further that some of these theories claim that the governments are explicitly allowing alien abduction.
Majestic 12, also known as Majic-12, and MJ-12 for short, is a purported organization that appeared in fake documents first circulated by ufologists in 1984, and that some UFO conspiracy theories still claim to have existed. The organization is claimed to be the code name of an alleged secret committee of scientists, military leaders, and government officials, formed in 1947 by an executive order by U.S. President Harry S. Truman to facilitate recovery and investigation of alien spacecraft. The Federal Bureau of Investigation (FBI) declared the documents to be "completely bogus", and many ufologists consider them to be an elaborate hoax. Majestic 12 remains popular among some UFO conspiracy theorists and the concept has appeared in popular culture including television, film, video games, and literature.
Grey aliens, also referred to as Zeta Reticulans, Roswell Greys or Greys, are purported extraterrestrial beings. They are frequent subjects of close encounters and alien abduction claims. The details of such claims vary widely. That said, Greys are typically described as being human-like with small bodies, smooth, grey-colored skin; enlarged, hairless heads; and large, black eyes. The Barney and Betty Hill abduction claim, which purportedly took place in New Hampshire in 1961, popularized Grey aliens. Precursor figures have been described in science fiction and similar descriptions appeared in early accounts of the 1948 Aztec UFO hoax and later accounts of the 1947 Roswell UFO incident.
The Roswell incident is a conspiracy theory which alleges that the 1947 United States Army Air Forces balloon debris recovered near Roswell, New Mexico was actually a crashed extraterrestrial spacecraft. Operated from the nearby Alamogordo Army Air Field and part of the top secret Project Mogul, the balloon was intended to detect Soviet nuclear tests. After metallic and rubber debris were recovered by Roswell Army Air Field personnel, the United States Army announced their possession of a "flying disc". This announcement made international headlines, but was retracted within a day. Obscuring the true purpose and source of the crashed balloon, the army subsequently stated that it was a conventional weather balloon.
Ufology, sometimes written UFOlogy, is the investigation of unidentified flying objects (UFOs) by people who believe that they may be of extraordinary origins. While there are instances of government, private, and fringe science investigations of UFOs, ufology is generally regarded by skeptics and science educators as an example of pseudoscience.
The extraterrestrial hypothesis (ETH) proposes that some unidentified flying objects (UFOs) are best explained as being physical spacecraft occupied by extraterrestrial intelligence or non-human aliens, or non-occupied alien probes from other planets visiting Earth.
In ufology, the psychosocial hypothesis, abbreviated PSH, argues that at least some UFO reports are best explained by psychological or social means. It is often contrasted with the better-known extraterrestrial hypothesis (ETH), and is particularly popular among UFO researchers in the United Kingdom, such as David Clarke, Hilary Evans, the editors of Magonia magazine, and many of the contributors to Fortean Times magazine. It has also been popular in France since the publication in 1977 of a book written by Michel Monnerie, Et si les ovnis n'existaient pas?.
Eduard Albert Meier, commonly nicknamed "Billy", is the founder of a UFO religion called the "Freie Interessengemeinschaft für Grenz- und Geisteswissenschaften und Ufologiestudien" and alleged contactee whose UFO photographs are claimed to show alien spacecraft. Meier claims to be in regular contact with extraterrestrial beings he calls the Plejaren. He also presented other material during the 1970s such as metal samples, sound recordings and film footage. Meier claims to be the seventh reincarnation after six prophets common to Judaism, Christianity, and Islam: Enoch, Elijah, Isaiah, Jeremiah, Immanuel (Jesus), and Muhammad.
Stanton Terry Friedman was an American–Canadian nuclear physicist and professional ufologist who was based in Fredericton, New Brunswick, Canada.
Contactees are persons who claim to have experienced contact with extraterrestrials. Some claimed ongoing encounters, while others claimed to have had as few as a single encounter. Evidence is anecdotal in all cases.
Philip Julian Klass was an American aviation/aerospace journalist and UFO researcher, best known for his skepticism regarding UFOs. In the ufological and skeptical communities, Klass inspires polarized appraisals. He has been called the "Sherlock Holmes of UFOlogy". Klass demonstrated "the crusader's zeal for what seems 'right,' regardless of whether it brings popular acclaim," a trait he claimed his father instilled in him. "I've found," said Klass, "that roughly 97, 98 percent of the people who report seeing UFOs are fundamentally intelligent, honest people who have seen something—usually at night, in darkness—that is unfamiliar, that they cannot explain." The rest, he said, were frauds.
The Center for UFO Studies (CUFOS) is a privately funded UFO research group. The group was founded in 1973 by J. Allen Hynek, who at the time was chair of the Department of Astronomy at Northwestern University in Illinois.
The Condon Committee was the informal name of the University of Colorado UFO Project, a group funded by the United States Air Force from 1966 to 1968 at the University of Colorado to study unidentified flying objects under the direction of physicist Edward Condon. The result of its work, formally titled Scientific Study of Unidentified Flying Objects, and known as the Condon Report, appeared in 1968.
Orfeo Matthew Angelucci was an American author, lecturer, and one of the so-called UFO contactees who rose to prominence in the 1950s. Angelucci claimed that he had experiences with extraterrestrial beings. He lectured extensively on the subject of his extraterrestrial encounters during the 1950s and 1960s.
UFO Files is an American television series that was produced from 2004 to 2007 for the History Channel. The program covers the phenomena of unidentified flying and submerged objects, close encounters with alleged extraterrestrial life, and alleged military and government cover-up conspiracies.
A flying saucer, or flying disc, is a purported disc-shaped UFO. The term was coined in 1947 by the news media for the objects pilot Kenneth Arnold claimed flew alongside his airplane above Washington State. Newspapers reported Arnold's story with speed estimates implausible for airplanes of the period. The story spurred a wave of hundreds of sightings across the United States, including the Roswell incident and Flight 105 UFO sighting. The concept quickly spread to other countries. Early reports speculated about secret military technology, but flying saucers became synonymous with aliens by 1950. The term has gradually been supplanted by the more general military terms unidentified flying object (UFO) and unidentified anomalous phenomena (UAP).
Karl Tomlinson Pflock was a CIA intelligence officer, Deputy Assistant Secretary of Defense in the Reagan Administration, strategic planner, UFO researcher, and author of both fiction and non-fiction. He was best known for his book Roswell: Inconvenient Facts and the Will to Believe.
The Aztec, New Mexico, UFO hoax was a flying saucer crash alleged to have happened in 1948 in Aztec, New Mexico. The story was first published in 1949 by author Frank Scully in his Variety magazine columns, and later in his 1950 book Behind the Flying Saucers. In the mid-1950s, the story was exposed as a hoax fabricated by two con men, Silas M. Newton and Leo A. Gebauer, as part of a fraudulent scheme to sell supposed alien technology. Beginning in the 1970s, some ufologists resurrected the story in books claiming the purported crash was real. In 2013, an FBI memo claimed by some ufologists to substantiate the crash story was dismissed by the bureau as "a second- or third-hand claim that we never investigated".
John Olsen Lear was an American aviator and UFO conspiracy theorist. A son of Learjet magnate Bill Lear, Lear set multiple records, later flying cargo planes for the CIA during the Vietnam era. In the 1980s, he began speaking of alien collusion with secret governmental forces, and in the second half of the decade, Lear was "probably the most influential source" of UFO research.
Greer claims that he is a contactee who has coined the term "close encounter of the fifth kind" to describe human-initiated contact with extraterrestrials.
