🇺🇸 USAF — Project Blue Book
In August 1952, a photo technician at Davis-Monthan Air Base in Arizona captured an image of an unidentified object that appeared to be a balloon. The classified report indicates the object was observed for over 10 minutes, showing erratic movements and changes in direction. Two witnesses, including an Air Force officer, described the object as bright, blue-white, and round in shape. Although a balloon was considered a possibility, no conclusive evidence was found. The report also mentions that other residents of Tucson reported seeing similar objects, adding to the mystery of the sighting.
The report includes photographs of the object and detailed weather data, but the phenomenon could not be identified. The final evaluation of the case did not reach a definitive conclusion, making it one of those UFO cases that remain unsolved.
