Blue-green UFO seen from a car in Dayton, Ohio

Summary

An engineer reported a round to teardrop-shaped object, blue-green in color, seen from his car in Dayton, Ohio. The object appeared at a 45-degree elevation to the east and disappeared near the horizon. The witness observed it for 3-4 seconds in October 1953 but did not report it officially until several years later. The official conclusion was that it was unlikely to be a bright fireball. The report includes detailed information on location, direction, and duration, but no physical evidence or photographs were found.
