Circular UFO sighted by military personnel in Utah in 1950

Summary

In July 1950, three staff sergeants at Hill Air Force Base in Utah observed an unidentified aerial object. The object, described as circular, about 50 feet long and silver in color, passed at a high altitude over the base. Witnesses reported no sound or exhaust trail, and its estimated speed ranged between 5 and 700 miles per hour. Although they tried to track it using radar, the object disappeared before the equipment was fully operational. Officials concluded it might be a balloon, but an aircraft was not ruled out.

The sighting lasted three minutes, with no photographs or radar contact. The case was officially recorded by the Air Force and classified, only to be declassified after 12 years. Despite initial investigations, the object was never conclusively identified, adding another mystery to the UFO history of the 1950s.
