Circular UFO 1953 San Antonio

Summary

A civilian observer in San Antonio, Texas, reported a large, dark gray, round object with a faint vapor trail. It was estimated to be traveling at 300 mph at around 10,000 feet altitude. The object was observed for 20-30 seconds, moving silently overhead. Despite the official conclusion suggesting it could be an unidentified aircraft, the speed and altitude estimates didn't align with the observation duration. The witness described a clearly circular object about 50 feet in diameter, with dim yellow lights along the edge. No photos or physical evidence were collected, but the report includes details on direction, weather, and the observer's confidence level.
