🇺🇸 USAF — Project Blue Book
In July 1958, a civilian observer in Beaver Falls, Pennsylvania, spotted a small, round, yellowish-green object. The witness, a 15-year-old, saw it for 50 seconds through binoculars, describing a slow movement toward the southwest. Although initially thought to be an aircraft, the lack of precise data prevented a conclusive evaluation. The general description was vague, complicating any certain identification.
The official report marked "Insufficient data for evaluation," reflecting the ambiguity of the testimony. There was no physical evidence or photographs, and weather data did not provide clarity. Although the slow, straight-line movement suggested an aircraft, it could not be confirmed. This case remains one of those mysteries that remind us how difficult it is to accurately identify an object in the sky with only a visual description.
