An unidentified flying object (UFO) is any perceived aerial 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 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.
George Adamski was a Polish-American author who became widely known in ufology circles, and to some degree in popular culture, after he displayed numerous photographs in the 1940s and 1950s that he said were of alien spacecraft, claimed to have met with friendly Nordic alien Space Brothers, and claimed to have taken flights with them to the Moon and other planets.
The Roswell incident centers on the 1947 recovery of metallic and rubber debris from a military balloon that was recovered by military personnel from Roswell Army Air Field. Decades later, conspiracy theories claimed that the debris was from a flying saucer which had been covered up by the United States government. In 1994, the United States Air Force published a report identifying the crashed object as a nuclear test surveillance balloon from Project Mogul.
Robert Scott Lazar is an American conspiracy theorist and self-proclaimed physicist who claims he was hired in the late 1980s to reverse-engineer extraterrestrial technology. This work supposedly occurred at a secret site called "S-4", a subsidiary installation allegedly located several kilometers south of the United States Air Force facility popularly known as Area 51.
The Maury Island incident refers to claims made by Fred Crisman and Harold Dahl of falling debris and threats by men in black following sightings of unidentified flying objects in the sky over Maury Island in Puget Sound. The pair would later claim the events had occurred on June 21, 1947.
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 nuclear physicist and professional ufologist who resided in New Brunswick, Canada. He was the original civilian investigator of the Roswell UFO incident.
Philip Julian Klass was an American journalist, and UFO researcher, 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.
Francis Joseph Xavier Scully; was an American journalist, author, humorist, and a regular columnist for the entertainment trade magazine Variety.
In ufology, conspiracy theory, science fiction, and comic book stories, claims or stories have circulated linking UFOs to Nazi Germany. The German UFO theories describe supposedly successful attempts to develop advanced aircraft or spacecraft prior to and during World War II, further asserting the post-war survival of these craft in secret underground bases in Antarctica, South America, or the United States, along with their creators.
Elizabeth Klarer was a South African woman who, starting in 1956, publicly claimed to have been contacted by aliens multiple times between 1954 and 1963. Klarer's first visitation supposedly occurred when she was seven and she was one of the first women to claim a sexual relationship with an extraterrestrial. She promoted an ideal of a better world and beliefs in a cosmic consciousness. In her book Beyond the Light Barrier, she strived to convey a message of peace, love, understanding and environmentalism, which she credited to the superior wisdom of an advanced and immaculately utopian Venusian civilization. She promoted conspiracy theories of an international cover-up that kept vital information from the public, and claimed to have been threatened with abduction to press her into revealing details about alien technology.
James Willett Moseley was an American observer, author, and commentator on the subject of unidentified flying objects (UFOs). Over his nearly sixty-year career, he exposed UFO hoaxes and engineered hoaxes of his own. He was best known as the publisher of the UFO newsletters Saucer News and its successor Saucer Smear, which became the longest continuously published UFO journal in the world.
A flying saucer is a descriptive term for a type of flying craft having a disc or saucer-shaped body, commonly used generically to refer to an anomalous flying object. The term was coined in 1947 but has generally been supplanted since 1952 by the United States Air Force term unidentified flying objects. Early reported sightings of unknown "flying saucers" usually described them as silver or metallic, sometimes reported as covered with navigation lights or surrounded with a glowing light, hovering or moving rapidly, either alone or in tight formations with other similar craft, and exhibiting high maneuverability.
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 Twin Falls saucer hoax was a hoaxed flying disc discovered in Twin Falls, Idaho, United States, on July 11, 1947. Amid a nationwide wave of alleged "flying disc" sightings, residents of Twin Falls reported recovering a 30 in (76 cm) "disc". FBI and Army officials took possession of the disc and quickly proclaimed the object to be a hoax. Press reported that local teenagers admitted to perpetrating the hoax.
