Project 10073 Record Card and Related Correspondence — Rialto and Monrovia, California, October 1955

This document consists of a Project 10073 record card and two subsequent military teletype reports regarding a sighting on October 22, 1955. The incident involved a visual observation of an object described as blue-white in color, which appeared to look like a meteor with fragments falling. The object was reported to have produced a bright flash of light and was visible for approximately three seconds. The reports originated from the 669th Aircraft Control and Warning Squadron at Port Hueneme, California, and were directed to various Air Force intelligence commands, including the Air Technical Intelligence Center at Wright-Patterson Air Force Base. The primary witness, a 32-year-old Ground Observer Corps (GOC) controller in Rialto, California, reported the event at 230215Z. A second report from Monrovia, California, noted the object as a bright flash of light, though the post had closed before further information could be gathered. The official conclusion recorded on the Project 10073 card is that the object was an astronomical meteor. The documentation includes specific coordinates for the sightings and confirms that no radar contact was made and no photographs were taken. The reports were signed by 1/LT. A.E. Sanders.
