Unsealed: Alien Files – Alien Spaceships episode 40
An unidentified flying object (UFO) is any aerial phenomenon that cannot immediately be identified or explained. Most UFOs are identified on investigation as conventional objects or phenomena. The term is widely used for claimed observations of extraterrestrial spacecraft.
The term “UFO” (or “UFOB”) was coined in 1953 by the United States Air Force (USAF) to serve as a catch-all for all such reports. In its initial definition, the USAF stated that a “UFOB” was “any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object”. Accordingly, the term was initially restricted to that fraction of cases which remained unidentified after investigation, as the USAF was interested in potential national security reasons and “technical aspects” (see Air Force Regulation 200-2).
During the late 1940s and through the 1950s, UFOs were often referred to popularly as “flying saucers” or “flying discs”. The term UFO became more widespread during the 1950s, at first in technical literature, but later in popular use. UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security, and, more recently, in the 2010s, for unexplained reasons. Nevertheless, various studies have concluded that the phenomenon does not represent a threat to national security, nor does it contain anything worthy of scientific pursuit (e.g., 1951 Flying Saucer Working Party, 1953 CIA Robertson Panel, USAF Project Blue Book, Condon Committee).
The Oxford English Dictionary defines a UFO as “An unidentified flying object; a ‘flying saucer'”. The first published book to use the word was authored by Donald E. Keyhoe.
As an acronym, “UFO” was coined by Captain Edward J. Ruppelt, who headed Project Blue Book, then the USAF’s official investigation of UFOs. He wrote, “Obviously the term ‘flying saucer’ is misleading when applied to objects of every conceivable shape and performance. For this reason the military prefers the more general, if less colorful, name: unidentified flying objects. UFO (pronounced Yoo-foe) for short.” Other phrases that were used officially and that predate the UFO acronym include “flying flapjack”, “flying disc”, “unexplained flying discs”, and “unidentifiable object”.
