Project 10073 Record Card — Sighting Report, Lyons, Colorado, 18 June 1959

This document contains a collection of records regarding a UFO sighting reported by a housewife in Lyons, Colorado, on the morning of June 18, 1959. The witness, a 49-year-old woman, reported hearing a 'terrific roar' that she described as unlike any jet or commercial airliner she had previously heard. Upon rushing outside, she observed a dull gray, three-pointed object, which she estimated to be approximately 20 feet long and 8 feet wide at the base. She described the object as 'tumbling' end-over-end, moving from south to north at a speed she characterized as faster than any jet she had ever seen. The witness noted that the sound did not follow the object but instead drifted off toward the mountains and faded away. She speculated in her correspondence that the object might have been a nose cone re-entering the earth's atmosphere. The report was initially received by the Air Defense Command at Ent Air Force Base, Colorado, and subsequently forwarded to the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base, Ohio, on June 25, 1959. Major Lawrence J. Tacker of the Office of Information Services acknowledged the report on July 9, 1959, stating that the initial information provided was insufficient to reach a valid conclusion. Consequently, the Air Force provided a questionnaire (ATIC Form 164) to the witness to gather more detailed data for further analysis and evaluation. The file includes the original correspondence from the witness, the completed questionnaire, and internal military routing slips documenting the administrative handling of the case.
