Gray UFO sighted by pilots over Maine

Summary

In January 1953, a pilot and his radar observer in an F-94 reported a mysterious object while flying at 23,000 feet over Maine. The object, described as a dark gray disc, remained at the same altitude as the aircraft and showed no signs of movement or maneuvers. Despite attempts to close in, limited fuel forced the pilots to abandon the pursuit. Reports detail that the object had no lights, smoke, or noise, and remained stationary during the four-minute observation. Investigators concluded it was neither a balloon nor a known aircraft, leaving the nature of the phenomenon unresolved.
