Project 10073 Record — West Riverside, California, 23 September 1954

This document is a Project 10073 record concerning a civilian sighting of an unidentified aerial phenomenon in West Riverside, California, on September 23, 1954. The observer reported a single object that appeared as a dull red light, which subsequently changed to white. The object was observed for approximately one to two minutes, during which it performed a 180-degree turn at an extremely high speed before disappearing suddenly. The weather conditions at the time were reported as clear and unlimited, with visibility of five miles in haze. The report includes administrative routing information, indicating that the sighting was communicated to the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base, as well as the 27th Air Division Defense and the Director of Intelligence at HQ USAF. Meteorological data from March Air Force Base was included in the assessment. Despite the details provided, the official conclusion reached by the investigating authorities was that there was insufficient data to conduct a meaningful analysis of the event. The report confirms that no photographs or physical evidence were obtained, and there was no radar contact associated with the sighting.
