Summary
The OCR text on pages 10 and 11 is too heavily garbled to support reliable transcription. However, the structured portions of the case file are readable enough to provide a summary.
On the evening of April 24, 1957, between 2100 and 2200 hours (9 p.m. and 10 p.m.), a witness at Port Columbus, Ohio observed a single unidentified object in the night sky. The object appeared as a bright white light, roughly the size of a baseball or flashlight. It moved erratically across the sky, sometimes hovering in place, before finally disappearing toward the west. The observation lasted approximately one hour.
According to the witness's responses on the official Air Force questionnaire, the object had no discernible features other than its bright white color. The edges appeared sharp and well defined. The witness reported no unusual behavior such as sudden acceleration, shape changes, flickering, or smoke emission. The sky conditions at the time were clear with no wind, though specific weather details are partially obscured in the OCR.
The Air Force classified this sighting as "unidentified" on its summary card, though a handwritten notation on the first page suggests the evaluators considered it "probably balloon." The full case file, comprising 11 pages as held by the National Archives under microfilm T1206, Roll 27, is reproduced below.
