🇺🇸 USAF — Project Blue Book
In April 1967, a military officer at Fort Carson, Colorado, reported observing an unidentified flying object. The declassified document describes an observation lasting at least ten minutes, during which the object displayed rapid side-to-side movements and a yellowish glow that dimmed occasionally. Witnesses confirmed the presence of the UFO, which was seen from multiple locations in the area. Although explanations such as helium balloons or light reflections were considered, the report did not reach a clear conclusion. The exact nature of the phenomenon remains a mystery.
