🇺🇸 USAF — Project Blue Book
In July 1955, a witness in Santa Maria, California, observed a large silver object without wings moving slowly from east to west. The object was seen for an unknown duration and the witness managed to take photos of the event. Although the report mentions that pictures were taken, the negatives were never received by the central archive, as the observer did not send them as requested. The official evaluation could not conclusively determine what the object was, though possibilities such as balloons, aircraft, or astronomical phenomena were considered.
