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 UAPs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.
Donald Edward Keyhoe was an American Marine Corps naval aviator, writer of aviation articles and stories in a variety of publications, and tour manager of aviation pioneer Charles Lindbergh.
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 appears in UFO conspiracy theories. 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 concept originated in a series of supposedly leaked secret government documents first circulated by ufologists in 1984. Upon examination, 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 and literature.
The Roswell incident is a collection of events and myths surrounding the 1947 crash of a United States Army Air Forces balloon near Roswell, New Mexico. 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 was 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 This announcement made international headlines but was retracted within a day.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 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.
Project Blue Book was the code name for the systematic study of unidentified flying objects by the United States Air Force from March 1952 to its termination on December 17, 1969. The project, headquartered at Wright-Patterson Air Force Base, Ohio, was initially directed by Captain Edward J. Ruppelt and followed projects of a similar nature such as Project Sign established in 1947, and Project Grudge in 1949. Project Blue Book had two goals, namely, to determine if UFOs were a threat to national security, and to scientifically analyze UFO-related data.
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?.
Stanton Terry Friedman was an American–Canadian nuclear physicist and professional ufologist who was based in Fredericton, New Brunswick, Canada.
James Edward McDonald was an American physicist. He is best known for his research regarding UFOs. McDonald was a senior physicist at the Institute for Atmospheric Physics and a professor of meteorology at the University of Arizona in Tucson.
Philip Julian Klass was a preeminent 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 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.
Paul Frederic Bennewitz, Jr. was an American businessman and UFO investigator. According to multiple sources, Bennewitz was the target of a government disinformation campaign that ultimately led to his psychiatric hospitalization.
Bruce S. Maccabee was an American optical physicist employed by the U.S. Navy, and a ufologist.
The Kaikoura lights is a name given by the New Zealand media to a series of UFO sightings that occurred in December 1978, over the skies above the Kaikōura mountain ranges in the northeast of New Zealand's South Island. The first sightings were made on 21 December when the crew of a Safe Air Ltd cargo aircraft began observing a series of strange lights around their Armstrong Whitworth AW.660 Argosy aircraft, which tracked along with their aircraft for several minutes before disappearing and then reappearing elsewhere. The UFO was very large and had five white flashing lights that were visible on the craft. Some people say that they could see some little disks drop from the UFO and then disappear. The pilots described some of the lights to be the size of a house and others small but flashing brilliantly. These objects appeared on the air traffic controller radar in Wellington and also on the aircraft's on-board radar.
The McMinnville UFO photographs, also known as the Trent UFO photos, were two photographs of a purported UFO taken by a farming couple, Paul and Evelyn Trent near McMinnville, Oregon, United States on May 11, 1950. The photos were reprinted in Life magazine and in newspapers across the nation and are often considered to be among the most famous and clearest photographs ever taken of a UFO. Most UFO skeptics consider these photographs a hoax, although many ufologists continue to argue that the photos actually depict a genuine three dimensional unidentified flying object in the sky.
Investigation and analysis of reported UFO incidents under the federal government of the United States has taken place under multiple branches and agencies, past and current, since 1947. In spite of decades of interest, there remains no evidence that there are any purported UFOs with extraordinary provenance and, indeed, those identified all have been shown to be natural phenomena, human technology, misapprehensions, delusions, or hoaxes.
