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.
Hector International Airport is a civil-military public airport three miles (5 km) northwest of Fargo, in Cass County, North Dakota, United States. The busiest airport in North Dakota, it is owned by the City of Fargo Municipal Airport Authority. Fargo Air National Guard Base is located adjacent to the airport.
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.
The "Roswell incident", or simply "Roswell", was the July 1947 recovery of metallic and rubber debris from a crashed military balloon by Roswell Army Air Field personnel, who issued a press release announcing possession of a "flying disc". Decades later, conspiracy theories claimed that debris from an alien spaceship had been covered up by the government. In response, in 1994 the United States Air Force published a report concluding the crashed object was a top secret nuclear test surveillance balloon from Project Mogul.
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.
On January 7, 1948, 25-year-old Captain Thomas F. Mantell, a Kentucky Air National Guard pilot, died in the crash of his P-51 Mustang fighter plane near Franklin, Kentucky, United States, after being sent in pursuit of an unidentified flying object (UFO). Mantell pursued the object in a steep climb and disregarded suggestions to level his altitude. At high altitude, he blacked out from a lack of oxygen; his plane went into a downward spiral and crashed. The incident was among the most publicized of early UFO reports. Later investigation by the United States Air Force's Project Blue Book indicated that Mantell died chasing a Skyhook balloon, which, in 1948, was a top-secret project that he would not have known about.
The Robertson Panel was a scientific committee which met in January 1953 headed by Howard P. Robertson. The Panel arose from a recommendation to the Intelligence Advisory Committee (IAC) in December 1952 from a Central Intelligence Agency (CIA) review of the U.S. Air Force investigation into unidentified flying objects, Project Blue Book. The CIA review itself was in response to widespread reports of unidentified flying objects, especially in the Washington, D.C. area during the summer of 1952.
The Lubbock Lights were an unusual formation of lights seen over the city of Lubbock, Texas in August and September 1951. The Lubbock Lights incident received national publicity in the United States as a UFO sighting, and was investigated by the U.S. Air Force. According to Ruppelt, Officially all of the sightings, except the UFO that was picked up on radar, are unknowns.
Project Sign or Project Saucer was an official U.S. government study of unidentified flying objects (UFOs) undertaken by the United States Air Force (USAF) and active for most of 1948. It was the precursor to Project Grudge.
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.
The Mariana UFO incident occurred in August 1950 in Great Falls, Montana. The film footage of the sighting is believed to be among the first ever taken of what came to be called an unidentified flying object. The footage was investigated by the U.S. Air Force, and initially found to be reflections from two F-94 jet fighters, which was later retracted.
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.
From July 12 to 29, 1952, a series of unidentified flying object (UFO) sightings were reported in Washington, D.C., and later became known as the Washington flap, the Washington National Airport Sightings, or the Invasion of Washington. The most publicized sightings took place on consecutive weekends, July 19–20 and July 26–27. UFO historian Curtis Peebles called the incident "the climax of the 1952 (UFO) flap" - "Never before or after did Project Blue Book and the Air Force undergo such a tidal wave of (UFO) reports."
The Exeter incident or Incident at Exeter was a highly publicized UFO sighting that occurred on September 3, 1965, approximately 5 miles (8 km) south of Exeter, New Hampshire, in the neighboring town of Kensington. Although several separate sightings had been made in the area by numerous witnesses in the weeks leading up to the specific incident, it was the September 3 sighting which eventually became by far the most famous, involving a local teenager and two police officers. In 2011, Skeptical Inquirer offered an explanation of the incident, based on details reported by the eyewitnesses.
The Lakenheath-Bentwaters Incident was a series of radar and visual contacts with unidentified flying objects over airbases in eastern England on the night of 13–14 August 1956, involving personnel from the Royal Air Force (RAF) and the United States Air Force (USAF). The incident has since gained some prominence in the literature of ufology and the popular media.
The Sperry UFO case was a sighting of an Unidentified Flying Object by the captain, Willis Sperry, and other crew of an American Airlines DC-6 airborne near Mount Vernon, Maryland on 29 May 1950.
UFO is a 1956 American semi-documentary about the development of the UFO phenomenon in the United States. Clips from the documentary have often been used in other UFO documentaries and television episodes related to UFOs.
The Coming of the Saucers is a 1952 book by original 'flying saucer' witness Kenneth Arnold and pulp magazine publisher Raymond Palmer. The book reprints and expands early articles the two had published in Palmer's Fate magazine. The work blends first-person accounts attributed to Arnold with third-person summations of UFO reports.
The Flight 105 UFO sighting occurred on July 4, 1947, when three crew members aboard a United Airlines flight reported seeing multiple unidentified objects in the skies over the Pacific Northwest. A week prior, private pilot Kenneth Arnold had reported seeing similar objects nearby – a sighting that was followed by nearly 800 "copycat" reports during the summer of 1947. Four days after the Flight 105 sighting, Roswell Army Air Field issued a press release stating that they had recovered a "flying disc"; that statement was quickly retracted after the crashed object was identified as a conventional weather balloon. The following month, on July 29, an air crew flying the same route also reported unidentified objects.
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:
