🇺🇸 USAF — Project Blue Book
In April 1952, two engineers in Longmeadow, Massachusetts, observed an unusual object for 40 minutes. They described a star-colored object that made rapid climbs and dives without emitting sound or exhaust. Its shape changed depending on altitude, and its brightness was four times that of a star. Despite being reported, no conventional explanation was found.
The classified report notes that the witnesses, both engineers with no astronomy training, observed the object from their homes. One called a neighbor to confirm the sighting. The object moved erratically at speeds exceeding any known aircraft. Although balloon and astronomical possibilities were considered, the case remained unresolved. The lack of physical evidence and the inability to identify the object make it one of the most intriguing cases from Project 10073.
