Spherical UFO in Harrisburg 1955

Summary

In June 1955, a civilian observer in Harrisburg, Pennsylvania, reported a round, silver object that appeared to descend onto railroad tracks. The object made no sound and then disappeared without a trace. Although the report mentions that 12 other witnesses in the area saw nothing, the possibility of a hallucination was considered. The document, part of Project 10073, failed to classify the sighting as a balloon, aircraft, or astronomical event, leaving the nature of the encounter unresolved.
