An unidentified flying object (UFO), or unidentified anomalous phenomenon (UAP), 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.
The term foo fighters was used by Allied aircraft pilots during World War II to describe various unidentified flying objects or mysterious aerial phenomena seen in the skies over both the European and Pacific theaters of operations.
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 1948. 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.
The Varginha UFO incident involves a series of events in 1996 when residents of Varginha, Brazil claimed seeing one or more strange creatures and at least one unidentified flying object (UFO). Other associated claims include the capture of one or more extraterrestrial beings by the Brazilian authorities, animal fatalities at a zoo, and a woman impregnated by an extraterrestrial. The reports have garnered extensive media coverage.
Black triangles are UFOs reported as having a triangular shape and dark color, typically observed at night, described as large, silent, hovering, moving slowly, and displaying pulsating, colored lights which they are able to turn off.
Green fireballs are a type of unidentified flying object (UFO) that has been reported since the early 1950s. Early sightings primarily occurred in the southwestern United States, particularly in New Mexico. Although some ufologists and ufology organizations consider green fireballs to be of artificial extraterrestrial origin, mainstream, non-pseudoscientific explanations have been provided, including natural bolides.
The Phoenix Lights were a series of widely sighted unidentified flying objects observed in the skies over the southwestern states of Arizona and Nevada on March 13, 1997.
Project Grudge was a short-lived project by the U.S. Air Force (USAF) to investigate unidentified flying objects (UFOs). Grudge succeeded Project Sign in February, 1949, and was then followed by Project Blue Book. The project formally ended in December 1949, but continued in a minimal capacity until late 1999.
Identifying unidentified flying objects (UFOs) is a difficult task due to the normally poor quality of the evidence provided by those who report sighting the unknown object. Observations and subsequent reporting are often made by those untrained in astronomy, atmospheric phenomena, aeronautics, physics, and perception. Nevertheless, most officially investigated UFO sightings, such as from the U.S. Air Force's Project Blue Book, have been identified as being due to honest misidentifications of natural phenomena, aircraft, or other prosaic explanations. In early U.S. Air Force attempts to explain UFO sightings, unexplained sightings routinely numbered over one in five reports. However, in early 1953, right after the CIA's Robertson Panel, percentages of unexplained sightings dropped precipitously, usually being only a few percent in any given year. When Project Blue Book closed down in 1970, only 6% of all cases were classified as being truly unidentified.
The 1976 Tehran UFO Incident was a radar and visual sighting of an unidentified flying object (UFO) over Tehran, the capital of Iran, during the early morning hours of 19 September 1976. During the incident, two Imperial Iranian Air Force F-4 Phantom II jet interceptors reported losing instrumentation and communications as they approached the object. These were restored upon withdrawal. One of the aircraft also reported a temporary weapons systems failure while the crew was preparing to open fire. An initial report of the incident was relayed to the U.S. Joint Chiefs of Staff on the day of the incident.
The Chiles-Whitted UFO encounter occurred at approximately 2:45 AM on July 24, 1948, in the skies near Montgomery, Alabama, United States. Two commercial pilots, Clarence S. Chiles and John B. Whitted, claimed to have observed a "glowing object" pass by their plane before it appeared to pull up into a cloud and travel out of sight.
This is a list of alleged sightings of unidentified flying objects or UFOs in Brazil.
Below is a partial list of alleged sightings of unidentified flying objects or UFOs in Canada.
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.
Japan Air Lines Cargo Flight 1628 was an unidentified flying object sighting on November 17, 1986 by a Japanese Boeing 747-200F cargo aircraft flying from Paris to Narita International Airport, near Tokyo. During the flight Captain Kenji Terauchi reported seeing three objects he described as "two small ships and the mother ship". The FAA in Anchorage only saw Flight 1628 on their radar. Two other nearby planes only saw Flight 1628 and no other objects. An FAA investigation of the incident characterized Terauchi as a "UFO repeater". Astronomers and investigators have determined that Terauchi probably mistook the planets Jupiter and Mars as UFOs. Contradictions between the three person crew as well as contradictions between the transcripts and later interviews with Terauchi have cast doubt that anything unusual happened.
UFOs: Past, Present, and Future is a 1974 documentary film that examines several prominent UFO sightings from the post-war to contemporary era. It was re-released in 1976 and 1979 under the title UFOs: It Has Begun to coincide with renewed interest in the subject due to the release of Steven Spielberg's Close Encounters of the Third Kind. It is based on the book UFOs: Past, Present, and Future by Robert Emenegger.
The Report on Unidentified Flying Objects is a 1956 book by then-retired Air Force UFO investigator Edward J. Ruppelt, detailing his experience running Project Bluebook. The book was noted for its suggestion that a few UFO sightings might be linked to spikes of atomic radiation. Contemporary media summarized four topics discussed in the book:
