Project 10073 Record Card — Springfield and Enon, Ohio, 1 July 1958

On July 1, 1958, at approximately 0345 local time, a civilian witness—identified as an Assistant Director of a Technical Division and a former Naval Aviator—observed an unidentified aerial phenomenon while driving west on Route 4 between Springfield and Enon, Ohio. The witness, accompanied by a passenger, reported seeing a yellow-white, flat, and rounded object with a fuzzy outline. The object moved across the sky from an azimuth of 235 degrees to 285 degrees. The witness noted that the object's speed was too fast for an aircraft but slower than a typical meteor. The observation lasted between 5 and 10 seconds. The witness reported no sound and described the object as glowing steadily without a shower of light, maintaining a straight trajectory before disappearing behind a tree line at a 10-degree elevation. The witness initially considered the possibility of a satellite or a meteor. The official conclusion recorded on the Project 10073 record card categorized the event as an 'Astronomical Meteor.' The witness completed a U.S. Air Force Technical Information Sheet on July 3, 1958, providing detailed sketches and bearing information to assist in the investigation.
