Project 10073 Record Card — Nellis AFB, Nevada, 18 April 1962

This document collection details a radar sighting that occurred on April 18, 1962, near the Nevada testing site, involving personnel from the 865th Radar Squadron at Nellis Air Force Base. The incident, recorded under Project 10073, involved a single unidentified radar blip that exhibited variable speed and an altitude of 10,800 feet. The object was tracked by AN/FPS20 and AN/FPS26 radar systems for approximately 32 minutes. The radar track initially headed northeast before disappearing instantly to the south. No visual contact was made, and the scope camera was not operational at the time of the event. Following the incident, a civilian named Louis Trifon inquired about the sighting, specifically asking if the object was a UFO and if it had been destroyed by a nuclear weapon. In a response dated September 21, 1962, Major C. R. Hart of the Air Force Office of Information stated that the official records classified the event as 'unidentified, insufficient data.' The Air Force further noted that while the track was characteristic of a U-2 aircraft or a high-altitude balloon, the available data was insufficient to confirm either as the source. The correspondence confirms that no interception or firing occurred regarding the object.
