UFO sighting in Georgetown 1955

Summary

In July 1955, a witness in Georgetown, Massachusetts, spotted a silvery disk-shaped object moving at high speed. The object, described as resembling an emery wheel, appeared for six seconds and followed a circular path from east to north. Although balloon or astronomical explanations were considered, investigators concluded it could be an aircraft. The lack of photos and the possibility of sunlight reflections off a high-flying jet suggested a conventional explanation.
