Project 10073 Record Card and Air Intelligence Information Report — Claremont, California, 30 July 1957

This document is an Air Intelligence Information Report regarding a UFO sighting that occurred on July 30, 1957, in Claremont, California. The report details an observation made by three civilians—David Romfeldt, Robert Sanchez, and Ralph Cordon Webster—who witnessed an object for approximately ten minutes. The witnesses used Bausch and Lomb binoculars to view the object, which they described as a round, dark-bodied craft with a single wing and yellow-to-orange balls of flame. The observers noted that the object moved in a straight path from east to west and did not make any sound. They estimated its altitude to be 30,000 feet or less. The report notes that a B-47 aircraft was in the area at a lower altitude, leaving a vapor trail, but the witnesses did not believe the object was the B-47. Major Francis J. Breslin, acting chief of the Combat Intelligence Division, evaluated the report. He concluded that while there was a possibility the object was a high-performance fighter or bomber aircraft, with the flames representing jet nacelles, the specific appearance of the fireballs on the wing remained not fully explainable. The document includes a record card for Project 10073 and confirms that no physical evidence was recovered.
