Project 10073 Record Card and Report of the Officers of the Day

This document consists of a Project 10073 record card and an accompanying Report of the Officers of the Day, dated May 13, 1952. The primary subject is a sighting reported by an individual identified as a commercial pilot and US Navy veteran, occurring on May 12, 1952, at 2116 EST over Kenton, Ohio. The witness reported observing a single unidentified object flying in a north-northeasterly direction at an altitude exceeding 20,000 feet and an estimated speed of 500 to 600 miles per hour. The witness explicitly stated that the object was not a jet aircraft and noted the absence of a vapor trail. Furthermore, the witness claimed to have observed similar unidentified objects on three previous occasions since 1947. The weather conditions were described as clear with no overcast. The report was initially received via a long-distance telephone call and subsequently relayed to the ATIC Duty Officer. The document also contains a brief, seemingly unrelated administrative note regarding a broken padlock on a stockroom door at Building 89, which was investigated by the WPAFB police department. The record card itself characterizes the initial report as 'vague' and provides no final conclusion regarding the nature of the object.
