Project 10073 Record Card and Related Correspondence — Hickman Canyon, Utah, October 1952

This document collection details a UFO sighting reported by two civilians on October 27, 1952, in the vicinity of Hickman Canyon, Utah. The witnesses, who were deer hunting in an isolated area, observed a saucer-shaped object with a dark center and two forward-facing exhaust pipes. They described the object as flying in a straight line at an altitude of approximately 3,000 feet before descending at a 15-degree angle and appearing to crash into South Mountain. The witnesses reported that the object produced a sound similar to an automobile or a high-speed car window defroster. Following the incident, the witnesses conducted their own search of the area but found no evidence of a crash or explosion. They subsequently reported the event to the Dugway Proving Ground. Military intelligence officers, including those from the 16th District Office of Special Investigations, were notified. An official air search of the area was conducted by Dugway personnel with negative results. The report notes that the witnesses later heard identical sounds in the area, leading to speculation that the phenomenon might be related to guided missile testing. The official conclusion recorded on the Project 10073 record card lists the event as having insufficient data for evaluation, while noting the possibility of guided missile tests. The file includes correspondence between the witnesses and military authorities, as well as detailed statements from the observers regarding their observations and subsequent attempts to investigate the site. The documents also contain maps and sketches of the flight path and the crash site area. The military authorities ultimately determined that no further investigative action was required under the provisions of Air Force Letter 200-5.
