🇺🇸 USAF — Project Blue Book
In February 1951, an officer and a soldier at Holloman AFB, New Mexico, observed an object that initially appeared on the horizon. The object had a round and conical shape, with white and orange colors. It hovered for a moment before ascending to about 45 degrees. Although no photos or radar were used, the object was continuously seen for almost an hour and a half. Its size was compared to a coffee cup at arm's length. The report concluded it was neither an aircraft nor a known astronomical body, but no definitive explanation was reached.
