Insufficient Data

Summary

On December 5, 1957, observers near O'Fallon, Illinois reported a fast, fiery object. The report describes a bullet-shaped or pencil-shaped object, fiery yellow and blue-white, with a slight break behind it and a long tail. Small parts or sparks appeared to come off it. The object was in view only briefly. The Air Force recorded the case under Project 10073, its official record for unidentified flying object reports. The card notes that the duration was too short for a rocket fired during nearby naval operations, and that this was probably a meteor sighting.
