Project 10073 Record Card — Delaware, Ohio, August 25, 1952

This document is a collection of correspondence and a formal record card regarding a UAP sighting on August 25, 1952, in Delaware, Ohio. The primary witness, an astronomer affiliated with Perkins Observatory and working for Dr. J. Allen Hynek, reported observing five objects for approximately one hour and fifteen minutes. The witness described the objects as having yellow-to-red lights that appeared to be attached to a craft. He noted that the objects oscillated 20 degrees on either side of south, with a movement frequency of 15 to 20 seconds through a 40-degree arc. The witness explicitly stated his belief that the objects were aircraft, noting that he could rule out astronomical possibilities completely.

In response to this report, the Air Technical Intelligence Center (ATIC) conducted an investigation to determine if any aircraft were airborne in the vicinity of Delaware, Ohio, during the time of the sighting. ATIC sent inquiries to several local aviation entities, including the Air National Guard at Lockbourne Air Force Base, Jones Flying Service, the Civil Aeronautics Administration at Port Columbus Airport, and North American Aviation, Inc. Each of these organizations responded in writing, confirming that they had no record of aircraft flights in the area during the specified time frame. Specifically, the Civil Aeronautics Administration noted that while an advertising blimp was flying over the Ohio State Fair on August 24, 25, and 26, there were no other unusual aircraft lights reported. The documentation includes the completed observer questionnaire, which provides detailed technical observations from the witness, including his assessment of the light magnitude and color, as well as his insistence that the lights were not astronomical in nature. The file concludes with the administrative correspondence confirming the lack of corroborating flight data from local airfields.
