🇺🇸 USAF — Project Blue Book
In September 1952, a civilian couple in Tucson, Arizona, observed six unidentified flat, shiny white objects. The objects were divided into two formations of three each, one traveling northwest and the other southwest. Despite clear visibility and detailed descriptions, there was no confirmation of local air activity or a clear explanation. The official evaluation considered the possibility of balloons or birds, but no definitive conclusion was reached.
The report includes precise weather data and diagrams showing the observers' positions and the objects. The main witness, a 36-year-old man, described the objects as silent and without propulsion trails, raising doubts about their conventional nature. Although weather balloons were mentioned as a possibility, no conclusive evidence was found. This case remains one of the unresolved mysteries of Project 10073.
