Project 10073 Record Card and Related Correspondence

This document collection centers on a Project 10073 record card documenting a sighting in Denver, Colorado, on August 31, 1958, alongside subsequent administrative correspondence regarding congressional inquiries into UFO reports. The primary sighting involved a civilian witness who observed three round, reddish-orange objects, described as the size of a baseball, traveling in an almost straight line before dropping behind trees. The official evaluation concluded there was insufficient data, noting that while Spica and Jupiter were setting in the southwest, they did not account for the third object reported. The document also includes a series of letters and internal memos involving Senator Frank J. Lausche and the Department of Defense. These documents address inquiries from a Mr. Earl J. Neff regarding potential unconventional aircraft or missile tests in the Cleveland, Ohio area on August 18-19, 1958. The Air Technical Intelligence Center (ATIC) conducted a thorough check of its files and informed the Senator that no reports of unidentified flying objects were found for those dates in Cleveland. The correspondence highlights the Air Force's standard procedure for handling public and congressional inquiries, which involved checking with flight test centers and providing fact sheets on the Air Force's position regarding UFOs. Additionally, the document contains a list of sightings from September 1-16, 1958, categorizing various reports as aircraft, balloons, astronomical phenomena, or insufficient data. The collection serves as a historical record of the administrative burden and investigative processes associated with the Air Force's UFO reporting program during the late 1950s, demonstrating how individual sighting reports were processed, evaluated, and integrated into broader intelligence assessments.
