Report of Investigation: Unusual Aerial Phenomena Sighted from Gonzales, Texas, and Vicinity

This document is a formal Report of Investigation issued by the United States Air Force Office of Special Investigations (OSI) on June 12, 1952. It details an inquiry into multiple reports of unusual aerial phenomena observed by residents of Gonzales, Texas, during the summer of 1951 and in May 1952. The investigation was prompted by information provided by the FBI Field Office in San Antonio. The report documents several specific sightings, including an object observed by a witness and his brother while driving on Main Street in Shiner, Texas, and another by a woman and her husband while driving on Highway 3. Witnesses described the objects as aluminum-colored, lacking markings or insignia, and moving in straight lines at speeds comparable to fighter planes. One witness reported an object appearing to vanish into a 'ball of fire.' The OSI conducted interviews with local figures, including the Sheriff of Gonzales County and a bank vice president, to evaluate the credibility of the witnesses. While some interviewees suggested that certain witnesses might be prone to exaggeration or a desire for publicity, they were generally regarded as honest and reliable members of the community. The report includes detailed technical data for one specific sighting, noting a 15-minute duration, an altitude of 22.5 degrees, and a lack of sound or odor. The investigation concluded with the status 'CLOSED,' though no definitive explanation for the phenomena was provided. The document is marked 'CONFIDENTIAL' and includes instructions for declassification after 12 years.
