Incident #139 Sighting Report — Osborn, Ohio, 9 July 1948

This document contains a sighting report for Incident #139, which occurred on July 9, 1948, in the North End of Osborn, Ohio. The report, processed by the Air Technical Intelligence Center (ATIC) and later included in the Project Grudge evaluation, details an observation made by a United States Air Force pilot. The pilot reported seeing a single, luminous, pale yellowish-white object traveling from east to west at an estimated speed of 500-600 MPH and an altitude of 3,000-4,000 feet. The observation lasted for approximately 1-2 seconds and was characterized by intermittent appearances at regulated intervals. The sky was reported as clear at the time of the incident. An evaluation of the report by Dr. Hynek, extracted from the Project Grudge report, notes that there is no obvious astronomical explanation for the sighting. The investigator highlights a significant discrepancy in the witness's account regarding the position of the moon. The witness claimed to see a quarter moon rising in the east-southeast at 2147 hours; however, the investigator points out that the moon would have been setting in the west-northwest at that time. This discrepancy leads the investigator to question the observer's orientation and suggests that the witness might have been looking in the wrong direction. The investigator further speculates that if the sky was indeed clear, the object might have been related to detached auroral streamers or searchlights playing on the sky, rather than an unidentified aerial phenomenon.
