Project 10073 Record — Roy, Utah, 31 March 1966

On March 31, 1966, at 1845Z, five witnesses in Roy, Utah, reported observing eleven unidentified objects maneuvering in the sky. The witnesses, who included staff from the Weber Basin Job Corp and local housewives, described the objects as round, white, and metallic, appearing to have a definite edge. The objects were estimated to be at an altitude of 20,000 feet and were observed for 15 to 20 minutes. The behavior of the objects was described as diverse, with some moving in circles at extreme elevation and others splitting up as if by command before fading from view. The sighting occurred during daylight hours under clear, bright conditions. The observers were watching a jet aircraft when they noticed the objects. An investigation by Hill Air Force Base confirmed that there were several aircraft in the area at the time, but radar reports indicated nothing unusual. The witnesses were evaluated as mature and of good judgment. The official conclusion noted on the Project 10073 record suggests the objects were possibly gulls, though the report explicitly states there were no clues as to the identity or explanation of the sighting.
