Project 10073 Record Card — Los Angeles, California, 21 June 1954

This document is a Project 10073 record card detailing an unidentified aerial phenomenon sighting that occurred on June 21, 1954, in Los Angeles, California. The report documents a single object observed by a civilian witness. The object was described as an oval shape, approximately 20 feet in diameter and 2 feet thick. The witness observed the object using 18-power binoculars. The reported flight path of the object was from west to east, eventually disappearing in the north at an estimated altitude of 400 feet. The weather conditions at the time were reported as stratus overcast with visibility reduced to one mile in haze. The report explicitly states that no photographs were taken and there was no radar contact. The official conclusion reached by the Air Technical Intelligence Center (ATIC) and the Flight Service Operations Officer was that there was insufficient data for a proper evaluation of the sighting, and the cause remains unknown. The document includes internal routing information, indicating it was processed through various military channels, including the Air Defense Command (ADC) and the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
