🇺🇸 USAF — Project Blue Book
In May 1952, a mysterious explosion lit up the skies over Seattle, Washington, causing widespread alarm. Witnesses reported seeing a bright blue object with sparks, diving steeply before exploding in a blinding flash. Astronomers and Air Force officials considered it a meteorite, though its unusual behavior raised doubts. The Air Force actively investigated, contacting astronomers and reviewing testimonies, but no fragments or clear evidence of an aircraft or missile were found. The lack of radar detection and the estimated altitude of the event added to the mystery, making it one of the most intriguing UFO cases in history.
