White UFO with Tail and Fast Flight

Summary

A civilian observer in Kentucky described a white UFO that appeared at dusk on June 30, 1956. The object, no larger than a locomotive, had a visible tail when turning. It was estimated to be between 5,000 and 20,000 feet above ground and moving very fast. The report concluded it could be an aircraft, as other aircraft were known in the area. The witness mentioned the objects were descending and turning, causing confusion. Despite the detailed description, there were no further reports or photographic evidence.
