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.
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 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, Washington, United States. The pair claimed that the events had occurred on June 21, 1947. The incident is widely regarded as a hoax, even by believers of flying saucers and UFOs.
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 can 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 explanations have been provided, including natural bolides.
Gran Canaria Airport is a passenger and freight airport on the island of Gran Canaria. It is an important airport within the Spanish air transport network, as it holds the sixth position in terms of passengers, and fifth in terms of operations and cargo transported. It also ranks first of the Canary Islands in all three categories, although the island of Tenerife has higher passenger numbers overall if statistics from the two airports located on the island are combined. The facility covers 553 hectares of land and contains two 3,100m runways.
Shag Harbour is a small fishing community on the South Shore of Nova Scotia. It is one of several small villages in the Municipality of the District of Barrington, Shelburne County. It has a population of roughly 400-450. Industry in the town centres on lobster fishing, which takes place from November to May.
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 Levelland UFO case occurred on November 2–3, 1957, on the highways around the small town of Levelland, Texas. Levelland, which in 1957 had a population of about 10,000, is located west of Lubbock on the flat prairie of the Texas South Plains. The case is considered by ufologists to be one of the most impressive in UFO history, mainly because of the large number of witnesses involved over a relatively short period of time. However, both the US Air Force and UFO sceptics have described the incident as being caused by either ball lightning or a severe electrical storm.
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.

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 Belgian UFO wave was a series of sightings of triangular UFOs in Belgium, which lasted from 29 November 1989 to April 1990.
