World UFO Day is celebrated on the day an American aviator claimed to see nine unusual objects flying near where?
Kenneth Arnold Kenneth A. Arnold (March 29, 1915 – January 16, 1984) was an American aviator and businessman. He is best known for making what is generally considered the first widely reported unidentified flying object sighting in the United States, after claiming to have seen nine unusual objects flying in tandem near Mount Rainier, Washington on June 24, 1947.
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."
