🇺🇸 USAF — Project Blue Book
In September 1957, at Perrin Air Force Base in Texas, a sighting of seven round objects with a nebulous and gaseous appearance was recorded. The observers, military personnel at the control tower, saw them move from north to southwest without any maneuvering. The objects disappeared like a light going out. Although other possibilities, such as balloons or astronomical phenomena, were considered, investigators concluded it was probably aircraft. The flight path aligned with the direction of Dallas, supporting the theory of aircraft. There was no physical evidence or photographs of the event.
