🇺🇸 USAF — Project Blue Book
Three round white objects the size of a shirt button were observed flying low over Racine, Wisconsin, in March 1956. A 16-year-old civilian witness saw them for half an hour using binoculars, describing how the objects circled and then vanished as if someone had turned off a light. Despite the long observation time, no sufficient details were obtained to identify the nature of the objects. The lack of photographs and the ambiguity of the description led to the conclusion that the data was insufficient for a definitive analysis. The official Project 10073 report did not reach a clear explanation, making it an intriguing case in UFO history.
