🇺🇸 USAF — Project Blue Book
A grayish disk-shaped object was observed for 21 minutes in Selma, North Carolina, in November 1957. The witness, a civilian, reported that the object was moving southwest and showed no signs of being an aircraft or leaving a trail. Despite the duration of the sighting, authorities concluded it was likely a balloon. The observation was made at low altitude and ended when the object was blocked by a building, adding mystery to the description.
The precise location and detailed description of the object, along with the absence of sound or emissions, raised doubts about its nature. Although conventional explanations were ruled out, the lack of physical or photographic evidence prevented a definitive classification. The official report suggests it could have been a balloon, but the testimony remains a curious case in UFO history.
