Transparent UFO with smoke trail seen by 100 factory workers

Summary

A round, transparent object leaving a smoke trail was observed over Morristown, Tennessee, on October 3, 1952. Around 100 factory workers saw it as they left work. The object was flying at low altitude, about 2-3 thousand feet, and moving in a straight line without maneuvers. Although one witness thought it might be a jet, no aircraft were reported in the area at the time. The object was described as transparent, of unknown size, and without visible propulsion.

Project Blue Book investigators concluded it was likely an aircraft, as the vapor trail suggested a jet. However, no physical evidence or photographs were found. The lack of precise weather data and no radar confirmation of aircraft in the area led to a limited evaluation of the case. Despite this, the collective testimony of so many witnesses remains an intriguing element in UFO sighting history.
