Insufficient Data

Summary

On December 12, 1957, a witness at Ellsworth Air Force Base, South Dakota reported a round white object about the size of a bright star. The object traveled in a straight horizontal course, then suddenly disappeared. The Air Force recorded the case under Project 10073, its official record for unidentified flying object reports. The card notes that the description, duration, and flight path matched a meteorite, and that the earth was passing through the peak of the Geminid meteor shower.
