PROJECT 10073 RECORD CARD - Silver Lake, Calif.

This document consists of a Project 10073 record card and an associated military teletype regarding an unidentified aerial phenomenon sighting on August 26, 1952. The incident occurred at 0010 PST in the vicinity of Silver Lake, California, at coordinates 36 degrees 39 minutes North, 116 degrees 26 minutes West. The witness reported observing a single, spherical, and brilliantly illuminated object. The object was initially seen moving on a northwesterly heading at an altitude estimated between three thousand and eight thousand feet. It then halted its flat trajectory momentarily before executing a sharp turn and entering a steep, greatly accelerated climb. During this climb, the object produced no exhaust until the maneuver began, at which point the light extinguished and a 'victor shaped' contrail appeared for approximately one second. The object was subsequently observed turning northeastward in the vicinity of Lathrop Wells, Nevada. The total duration of the sighting was estimated at three to five seconds. The report notes that there were no sounds associated with the object and that weather conditions were CAVU (Ceiling and Visibility Unlimited) with no known air activity or meteorological disturbances. The military investigation concluded that there was no physical evidence or photographic documentation of the event. The record card indicates that the case was marked for 'Insufficient Data for Evaluation' and that Air Force Form 112 was being forwarded for further processing. The teletype was routed to various commands, including HQ USAF in Washington D.C., Wright-Patterson AFB, Ent AFB, Pope AFB, and Langley AFB.
