🇺🇸 USAF — Project Blue Book
In April 1958, a witness in Washington observed a bright triangular object during dawn. The report notes that the object remained stationary in the sky for 15 minutes, drawing attention due to its brightness and shape. Although other explanations were initially considered, astronomical analyses concluded that the object matched the exact position of Venus at that time. This suggested that what was seen was simply the planet, although other possibilities were not entirely ruled out. The observation was recorded by local authorities and analyzed by the ATIC, which confirmed the astronomical explanation.
