16 July 1948
Cmt 1
1. At 2147 hours on 9 July 1948, the undersigned sighted an unidentified object flying from east to west at approximately three to four thousand feet over the north end of Osborn, Ohio.
2. The object appeared as a pale yellowish white light that seemed to glow. It was not a directed beam. The light was traveling at a rate of speed between five or six hundred miles. It appeared long enough to allow the observer to determine its flight path (approximately one to two seconds) and then went out. There was a pause of three seconds, the light then reappeared again for the same length of time, another three-second pause and the pattern was repeated. After the third appearance it was not seen again. The final sighting was made with the object at an angle of approximately $ 7 0^{\circ} $ to the horizon in front of the observer who was looking norht. The last sighting was slightly above the horizon to the west, just north of Patterson Field. The intermittent appearance of the light was at a regulated interval.
3. The sky was clear with about a quarter moon rising inthe East-southeast; however, nothing could be ascertained except the glow of the light. There was no sound or trail.
4. The undersigned was a reconnaissance pilot in World War II and served for eight months in the 160th Reconnaissance Sqd. (J. P.) flying FF-80 type aircraft. It is believed that his powers of observation are above average and that the estimates of speed can be considered to be fairly accurate.
