🇺🇸 USAF — Project Blue Book
In April 1952, a crew of a C-124 aircraft observed three blue, round objects near Bellevue Hill, Vermont. The objects appeared 20 degrees to the right of the aircraft's course and disappeared after 2-3 minutes. They then reappeared 20 degrees to the left, remaining visible for about a minute. No lights, vapor trails, or exhaust were observed. The crew described rapid movements with no clear explanation. Weather conditions were ideal, with unlimited visibility and strong winds. Despite multiple investigations, no conclusion was reached about the nature of the objects.
The lack of concrete data and the inability to identify the objects led to an official report with no conclusions. Explanations such as balloons, aircraft, or astronomical phenomena were ruled out. The incident was documented by several Air Force intelligence units, including the ATIC, and radar stations were consulted without results. The crew, supporting B-36 bombers on a simulated mission, had no further contact with the observers. The case remains categorized as "unknown," reflecting the ambiguity surrounding many UFO reports at the time.
