🇺🇸 USAF — Project Blue Book
In June 1961, a doctor from Bedford, Massachusetts, reported a luminous object crossing the sky for about 30 seconds. The object emitted regular flashes of approximately one second each, similar to the rhythm of aircraft anti-collision lights. Although initially not clearly identified, the report was analyzed by military and scientific experts. It was concluded that it was likely an aircraft whose anti-collision light matched the observed characteristics. The angular velocity of the object also supported this theory, calculating a speed compatible with a jet at a certain distance. The official report suggested it was not an astronomical phenomenon or a UFO, but a conventional aircraft seen from a considerable distance.
The case was documented by several institutions, including the Astrophysical Laboratory in Cambridge and the Aerospace Technical Intelligence Center of the Air Force. The witness, a doctor with experience in astronomical observations, described in detail the trajectory and behavior of the object. Despite the excellent visibility and precise data, the final report left no room for doubt: the object was consistent with an aircraft's anti-collision light. This conclusion was based on angular velocity calculations and the frequency of the flashes, which matched the technical specifications of anti-collision lights of the time. The case is an example of how precise data and collaboration between civilians and the military helped solve an apparently inexplicable sighting.
