Report of Unconventional Aircraft Sighting — Yuma, Arizona, 27 April 1952

On April 27, 1952, between 2030 and 2230 hours, a S/Sgt serving as a Chief of AACS Operating Location 1903-4 at Yuma County Airport, along with his wife, observed a series of unidentified aerial phenomena while at the Yuma Drive-In Theatre in Yuma, Arizona. The observer reported seeing approximately seven or eight objects that appeared as bright red or flame-colored discs, described as slightly larger than a fighter aircraft. The objects were observed traveling from the northeast to the southwest. The witness noted that the objects initially appeared to be 'falling stars' but were identified as something else when they performed abrupt changes in course and attitude. One object was observed making a rapid climb into the clouds, and another was seen pulling up abruptly into an overcast layer. The observer reported that the objects were silent and lacked distinctive aerodynamic features. On one occasion, two objects were seen in formation. The observer, who possessed professional experience in airport control and aircraft mechanics, explicitly stated that the objects could not have been conventional aircraft. The report was submitted to the Air Materiel Command at Wright-Patterson AFB in lieu of standard AF Form 112 due to a lack of forms at the station. The official conclusion recorded in the document is 'Unknown'.
