🇺🇸 USAF — Project Blue Book
In November 1954, a civilian in Frederick, Maryland, sighted a large, circular, saucer-shaped object that appeared to rotate as it disappeared. The object was observed for one minute and caused interference on the car radio. Although no photos were taken, the witness reported the object's unusual behavior. The evaluation noted that a field investigation was needed to determine the nature of the sighting, as the data was insufficient to classify it as a balloon, aircraft, or astronomical phenomenon.
