Correspondence Regarding UFO Sightings in Chicago and Udine, 1958-1961

This collection of documents details correspondence between the Air Force and a civilian organization, Civilian U.F.O. Research, regarding various unidentified aerial phenomena sightings between 1957 and 1961. The records include project record cards, internal military memoranda, and letters from Major William T. Coleman, Jr., addressing inquiries about specific incidents in Chicago, Illinois, and Udine, Italy. In the Chicago cases, witnesses reported red-orange objects hovering and moving at high speeds. The Air Force consistently responded that they had no record of these specific sightings or that they were likely balloons or satellites. For the Italian sightings, the documents describe a 'luminous object' observed over Udine, which was studied by Professor Dino di Colbertaldo. The Air Force's Foreign Technology Division noted that these sightings were likely Russian or United States satellites, though they lacked the precise tracking data required for definitive identification. The documents highlight the tension between civilian researchers seeking official conclusions under Air Force Regulation 200-2 and the military's standard response of insufficient data or conventional explanations. The records also include a newspaper clipping from Japan regarding a flying saucer report near Chitose Air Base, illustrating the global nature of these reports during the period. Throughout the correspondence, the Air Force maintains that many of these sightings, when investigated, are attributable to balloons, satellites, or other natural phenomena, while civilian researchers continue to press for more detailed official findings.
