UFO is an abbreviation for Unidentified Flying Object. Technically, a UFO is any object in the air which has not been or cannot be identified. However, the phrase is more commonly used to describe crafts that are of alien origin. — (Deep Throat) et al.
UFOs are frequently witnessed by soldiers during wartime — (E.B.E.). In fact, it is strongly held by believers in UFO phenomena that there is military complicity or involvement in abductions. — (Patient X) A UFO may also be described as a flying saucer, a fallen angel, or a foo fighter — (pilot, Fallen Angel, Apocrypha) et al. No other object has been misidentified as a flying saucer more often than the planet Venus. — (José Chung's From Outer Space)
