Project 1C973 Record Card — Palmdale, California, 13 September 1955

This document consists of a Project 1C973 record card and an associated teletype report detailing an unidentified aerial phenomenon sighting that occurred on September 13, 1955, near Air Force Plant 42 in Palmdale, California. The sighting, which lasted between 10 and 15 minutes, involved a single object described as having a flat top and bottom with rounded ends. The witness, identified as a 45-year-old civilian housewife, reported that the object was silver in color and appeared to be the size of a silver dollar at the observed distance. The object moved at a slow speed, estimated at 100 miles per hour, at an altitude between 4,000 and 5,000 feet above mean sea level. The witness noted a distinct, constant deep sound, described as a diesel roar with an afterburner-like overtone, and observed exhaust emanating from the rear of the object. The object was seen to change direction, following the contour of its rounded side. The report was processed by Major Robert T. Green and Captain Roy Furnas Jr. of the United States Air Force. The official conclusion reached by the investigating officers was that the object was a 'possible test vehicle,' noting that no other jet aircraft or traffic were reported in the area at the time of the sighting. The documentation includes specific technical details regarding the object's appearance, sound, and flight path, and confirms that no photographic evidence was obtained.
