Project 10073 Record Card — Highland Park, California, August 1952

This document contains records related to a UFO sighting reported on August 3, 1952, in Highland Park, California. The primary witness, identified as a member of the Los Angeles Police Department named Sublette, reported observing an extremely bright object for several minutes. Using a protractor, the witness estimated the object's position at 34 to 38 degrees above the horizon at an angle of 175 degrees. The witness reported that the object broke into six to eight pieces, which then appeared to descend toward the ground at high speed. The report was transmitted via teletype from Flight Service at March Air Force Base to the Director of Intelligence at the USAF in Washington D.C. and the Air Technical Intelligence Center at Wright-Patterson Air Force Base. The file includes a Project 10073 record card and a completed observer questionnaire. The questionnaire, filled out by a different individual (a housewife) regarding a separate sighting on August 17, 1952, at a drive-in theater in Monterey Park, California, describes a similar experience of observing luminous, round white objects that were not airplanes. The documents collectively reflect the military's process for gathering and documenting civilian reports of aerial phenomena during the early 1950s.
