🇺🇸 USAF — Project Blue Book
In September 1952, a witness in Bellefonte, Pennsylvania, reported seeing an object with blue, dull yellow, and red lights for over an hour. The object appeared on two consecutive nights and moved quickly across the sky. Initially considered a balloon or astronomical object, investigators concluded it was likely a blimp or a bright planet. The observer, along with others, noted a sound resembling a motorboat before the object suddenly disappeared. Despite investigations, no definitive explanation was reached, keeping the mystery around this case.
