🇺🇸 USAF — Project Blue Book
In 1948, a witness in Colorado reported three sightings of a silent green glowing object. The phenomenon was observed in Moffat, Blanca, and Monte Vista, and described as a bright "fireball" that vanished mid-air. Although the witness could not provide precise details about its size, shape, or altitude, his account was considered credible by investigators at the time. The official investigation concluded there was no conclusive evidence of a conventional explanation, such as meteors or aircraft. The report was classified and later downgraded over time, but remains an intriguing case of unidentified flying objects.
