Project 10073 Record Card — Fontana, California, 8 Jun 55 - 8 Jul 55

This document consists of a Project 10073 record card and a related UFOB index card detailing a series of sightings reported by a civilian in Fontana, California, between June 8, 1955, and July 8, 1955. The observer reported seeing round objects in the night sky that appeared either red and flashing or yellow and steady. Each observation lasted between ten and fifteen minutes, and the observer typically reported seeing one or two objects at a time. The investigation, conducted by AISS, included a review of local radio facility charts. The findings indicated that the observer's residence was situated in a well-populated and well-lit area, positioned between two aerodromes—one to the east and one to the west—with a beacon light located to the north. Furthermore, the flight path to Edwards Air Force Base was noted to pass directly over the observer's house. Based on these geographical factors, the official conclusion reached by the headquarters was that the observer had likely witnessed a combination of aircraft lights and the beacon light, rather than an unidentified aerial phenomenon. The report explicitly notes that no photographs were taken and there was no radar contact associated with these sightings.
