Project 10073 Record — Incident No. 376

This document details the investigation of a UFO sighting (Incident No. 376) that occurred on June 29, 1949, near Osborn, Ohio. The witness, identified as a USAF radio engineer, reported observing a single, aluminum-colored object that appeared larger than an F-80 aircraft. The object was described as having a level flight path, moving from southwest to northeast, and remaining in sight for approximately 3 to 4 seconds. The witness noted that the object made no sound and that its wings may have moved up and down. The observation took place between 2030 and 2100 hours. Following the report, the Flight Test Division conducted an investigation to determine if any military or experimental aircraft were in the area. Records indicated that the only jet aircraft in the air at the approximate time was an F-80 (serial #45-8479) returning from Chicago, which had landed by 1846 hours. Consequently, the military concluded there was no known flight test activity in the vicinity at the time of the sighting. The final official conclusion for the incident was categorized as 'Other (BIRDS),' with the assessment that the witness's estimation of the object's distance and size was significantly inaccurate. The document includes standard 'Guide to Investigation' forms used by the Air Materiel Command, which outline the criteria for reporting such sightings, including radar data, weather conditions, and physical evidence, though most of these fields were not applicable or were marked as negative in this specific case.
