🇺🇸 USAF — Project Blue Book
In December 1955, a teenager in Iowa observed a silent, bright object that exploded in the sky. The report details how the object changed colors and moved rapidly for about 15 seconds. Although initially considered a UFO, experts concluded it was a meteorite. Three independent witnesses, including a pilot and a control tower operator, reported the same sighting. The investigation included consultations with astronomers and meteorite experts, who confirmed the characteristics matched a common meteorite. The initial confusion was due to an overestimated observation time and the relative positions of observers near the horizon.
