Project 10073 Record Card - 4 December 1952 - Colorado Springs, Colorado

This document is a formal report from the 3924th Air Police Squadron at Camp Carson, Colorado, regarding an unidentified flying object sighted on December 4, 1952. The report, dated December 11, 1952, details the observations of an Air Force sergeant and a civilian who witnessed a round, aluminum-colored object traveling from east to west. The witnesses estimated the object to be approximately 20 feet in diameter, traveling at a speed between 600 and 800 miles per hour at an altitude of 6,000 to 8,000 feet. The object reportedly made several right-angle turns without any apparent loss of speed and appeared to tumble end-over-end, which the witnesses believed caused it to change shape. No sound was heard, and no vapor trails were observed. The weather conditions were described as clear with no wind. The report includes a narrative statement from the witnesses, who were on the Infiltration Range at Camp Carson at the time. The official conclusion reached by the evaluating agency, the Air Technical Intelligence Center, was that the object was 'possibly aircraft.' The report suggests that the changing shape and appearance could have been caused by the bright mid-day sun reflecting off an observation plane that was known to be in the area at the time of the sighting. The document includes various administrative forms, including a U.S. Air Force Technical Information Sheet, and maps of the Camp Carson area to pinpoint the location of the observers. The report was forwarded to the Director of Intelligence at the Headquarters of the United States Air Force and copied to the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
