Incident Report — New Kensington, Pennsylvania, May 21, 1950

This document consists of a series of reports and correspondence regarding an unidentified aerial phenomenon observed on May 21, 1950, in New Kensington, Pennsylvania. The primary witness, a sergeant, reported observing a round, flat object at approximately 2353 hours. The witness described the object as having three or four large, brilliant round lights with smaller lights in between, which appeared to rotate from left to right. The object was estimated to be at an altitude of 20,000 feet and was heard making a sound likened to heavy trucks on a wet highway, followed by a roar similar to a motor during a pre-flight warm-up. The object traveled south down the Allegheny River before executing a sharp right turn and heading west. The witness noted that they did not observe any jet-like exhaust flames or trails. The report also mentions that several similar incidents had been reported in the local newspapers in the surrounding areas of Springdale, Tarentum, and Arnold, Pennsylvania, during the preceding week. The witness speculated that these objects might be radio-controlled interceptor aircraft being tested by the U.S. Air Force to defend industrial targets. The documentation includes a formal acknowledgment of receipt from the Air Materiel Command at Wright-Patterson Air Force Base, dated June 1, 1950, signed by Colonel Fryan L. Davis, confirming that the report would be forwarded to the appropriate investigative office.
