Project 10073 Record Card and Correspondence Regarding 1951 Sighting

This document contains a Project 10073 record card and subsequent correspondence between a civilian witness and the United States Air Force regarding a UFO sighting in Los Angeles in November 1951. The witness, writing to President John F. Kennedy in September 1961, described observing a 400-foot-long, 60-foot-high metallic craft for three minutes. The witness provided a detailed, albeit speculative, theory on the craft's propulsion, suggesting it utilized a revolving ring and metal plates to manipulate electrical charges and gravity. The witness also claimed that their dog reacted to the object by barking. Major William T. Coleman, Jr., of the USAF, responded to the witness on September 27, 1961, and again on October 9, 1961. Coleman acknowledged the witness's interest but critiqued the propulsion theory as being too generally stated and lacking a mechanical basis for the rotation of the ring. Coleman also addressed the witness's mention of the Captain Thomas Mantell incident, clarifying that the Air Force attributed Mantell's death to hypoxia while pursuing a Skyhook balloon, not to an encounter with a metallic UFO. The Air Force concluded that the witness's report was likely due to psychological reasons, noting the ten-year delay between the event and the report. The file also includes a separate, unrelated report of a sighting by an airline first officer on November 2, 1951, near Abilene, Texas, involving a bright green object that appeared to explode into red balls of fire.
