Project 10073 Record Card and Related Correspondence — San Bernardino, California, January 1958

This document consists of a series of military teletype reports and a Project 10073 record card documenting a sequence of UFO sightings reported in San Bernardino, California, on January 27, 1958. Multiple civilian witnesses reported observing a bright, white, round object that moved in a zig-zag pattern, circled, and hovered over the area for approximately five minutes. One witness reported that the object appeared to be the size of a dime. The reports were forwarded to the Air Technical Intelligence Center (ATIC) and the Director of Intelligence at HQ USAF for evaluation. Following an investigation by the 27th Air Division, Captain Smith, a controller for the division, clarified that the sightings were not of an unidentified aerial phenomenon, but rather a T-33 aircraft conducting a test flight. The aircraft, which was operating out of Norton Air Force Base, was testing a new type of anti-collision light designed to make jet aircraft easier to spot. The report notes that the T-33 was accompanied by two other 'T-Birds' and a C-45 during the exercise. The final conclusion reached by the military authorities was that the reported 'UFO' was simply this specialized lighting equipment being evaluated in the night sky over San Bernardino.
