Santa Monica, California, [ILLEGIBLE] 1952Circa 1952

On August 30, 1952, a toolmaker in Santa Monica, California saw a series of bright, saucer-shaped objects moving erratically in the sky during the late afternoon. The main sighting took place around 4:15 p.m., approximately fifteen minutes before sunset, while the witness sat in a park near the ocean with a camera and a neighbor. The objects appeared and disappeared among clouds, sometimes vanishing and reappearing instantly in different locations. One object took off rapidly in a straight line and returned within two to three minutes, leaving a faint vapor trail. The witness estimated the objects were traveling at roughly 500 miles per hour and noted they displayed no banking or tilting motion, always maintaining a perfectly horizontal position. He described their light as pure white, like polished metal, and brighter than the sunlit clouds around them. About an hour later, while walking home at 11:30 p.m., the witness spotted another elongated bright object beneath the moon. It disappeared within seconds of him entering his door, but left a vapor trail angling upward. The witness provided detailed sketches and photographs, including a cloud photo he believed showed one of the objects partly obscured.

The Air Force received the report and sent the witness a formal questionnaire on September 15, 1952. In his written statement, he emphasized that the objects seemed to possess complete control over gravity and inertia, appearing and reappearing without acceleration or deceleration. He also noted that a neighbor had reported seeing a similar object a couple of months earlier from Topanga, which she observed for about two hours and described as having rounded corners and a slight swinging motion when stationary.

A second witness, whose name is partially obscured in the file, also submitted a questionnaire after being asked to report her sighting. She indicated she was part of a "Skywatch" program for civilian observers and saw multiple objects at a distance of 7,500 feet, traveling at high speed.

The Air Force evaluation section of the file marks the case as "unknown," meaning the objects were not identified as conventional aircraft, balloons, or other known phenomena. The full case file, consisting of 22 pages as held by the National Archives, is reproduced below.
