Summary
On January 23, 1953, a radar operator at Bergstrom Air Force Base in Austin, Texas detected an unusual target on his scope. T/Sergeant Gerald V. Kelley was working the ground-controlled approach radar, which helps guide aircraft to safe landings. While monitoring the 30-mile range setting, Kelley spotted a blip moving at high speed across his screen. The object appeared roughly twice the size of a normal aircraft target and had fuzzy, diffused edges.
Over the next hour, Kelley tracked the target as it moved in and out of range. The object would stop, remain stationary for short periods, then move again at speeds he estimated exceeded 350 miles per hour. He switched between the 30-mile and 15-mile range settings to handle routine air traffic control, but kept returning to check on the unusual target. At one point, he radioed the control tower and asked them to scan the area with binoculars. They reported seeing nothing. The target remained on his radar scope until approximately 1559 hours (3:59 p.m.) when it faded and disappeared.
The Air Force investigated the sighting thoroughly. An Electronics Branch officer at the Air Technical Intelligence Center noted that the target's behavior and appearance were unusual compared to known aircraft. However, that same officer also concluded that atmospheric conditions, particularly heavy rain clouds or ice-laden clouds, could have caused the radar return. The investigator requested additional weather data from the National Weather Service office in Asheville to help determine if anomalous propagation (unusual bouncing of radar signals through layers of the atmosphere) might explain the sighting. No scope photographs were taken, and no interception was attempted.
The case file contains 22 pages of original Air Force documentation held by the National Archives.
