🇺🇸 USAF — Project Blue Book
In July 1964, three spherical objects were observed over Denver. Witnesses described them as glowing balls resembling balloons, arranged like a string of beads. The flight was straight and fast, from northeast to southwest, disappearing after five seconds. Although considered a probable meteor, the detailed description and formation suggest something unusual.
A second sighting occurred in July 1964, this time with a single object. It was described as a white ball of fire the size of a car. The object descended, hovered for two minutes, and then ascended rapidly. Despite a clear and detailed observation, no conventional explanation was found. Both cases were officially reported but remain unidentified.
