Incident #158 Sighting Report — Groveport, Ohio, 1 August 1948

This document is an Agent Report from the 109th CIC Detachment, dated 9 August 1948, concerning an unidentified aerial phenomenon observed near Groveport, Ohio, on 1 August 1948. The primary witness, a student, was driving on Groveport Pike with his family when he observed a small black cloud between two white clouds. He described the object as having no definite shape, resembling an anti-aircraft shell burst. The object suddenly stretched into a wide streak with smaller vertical streaks, then turned and twisted before disappearing. The witness noted the object was at a very high altitude, moved in a westerly direction against a light wind, and made no sound. He estimated the length of the streak to be between one and two miles. The witness, who had prior experience observing anti-aircraft fire and aircraft vapor trails, stated that the phenomenon was unique and spontaneous, comparing its movement to a rubber band being stretched and twisted. A second witness, the student's wife, provided a statement that was substantially the same. The report includes sketches drawn by the witness illustrating the twisting motion of the streak. An evaluation by the Air Technical Intelligence Center (ATIC) suggests that the phenomenon was likely the smoke trail of a fireball, noting that the witness's description does not contradict the meteoric hypothesis. The document also includes an index of evaluations from the Project Grudge report, categorizing various incidents by their probability of being astronomical, conventional aircraft, or unexplained.
