🇺🇸 USAF — Project Blue Book
In April 1949, multiple witnesses in Utah reported unexplained aerial phenomena, including explosions, fireballs, and smoke trails. These events occurred across a wide area stretching from Salt Lake City to Logan and the Idaho border. Witnesses described explosions rattling windows, lingering smoke or vapor trails, and luminous objects moving at high speed. Some observed triangular shapes or fireballs, while others heard explosions minutes after seeing the phenomena. Although meteor explanations were considered, no conventional answers or debris were found. Authorities, including police and the FBI, investigated the cases, but no definitive conclusion was reached.
