UFO, how it works? Lets go inside of alien spaceship! Inside of UFO 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
The 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 », « unidentifiable object », and « flying saucer ».
The phrase « flying saucer » had gained widespread attention after the summer of 1947. On June 24, a civilian pilot named Kenneth Arnold reported seeing nine objects flying in formation near Mount Rainier. Arnold timed the sighting and estimated the speed of discs to be over 1,200 mph (1,931 km/h). At the time, he described the objects’ shape as being somewhat disc-like or saucer-like, leading to newspaper accounts of « flying saucers » and « flying discs ».
In popular usage the term UFO came to be used to refer to claims of alien spacecraft. and because of the public and media ridicule associated with the topic, some investigators prefer to use such terms as unidentified aerial phenomenon (or UAP) or anomalous phenomena, as in the title of the National Aviation Reporting Center on Anomalous Phenomena (NARCAP).
