Edward J. Ruppelt: Edward J. Ruppelt (July 17, 1923 – September 15, 1960) was a United States Air Force officer probably best known for his involvement in Project Blue Book, a formal governmental study of unidentified flying objects.  He is generally credited with coining the term "unidentified flying object", to replace the terms "flying saucer" and "flying disk" - which had become widely known - because the military thought them to be "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."
