Project 10073 Record: UFO Sighting, Tonopah AFS, Nev

This document details a UFO sighting report from 1 September 1965, involving multiple military installations in Nevada, including Tonopah AFS, Fallon NAAS, and Winnemucca AFS. The incident lasted for three hours and fifteen minutes. Ground observers described the object as oblong, with a green end, a red end, and a glowing white center, comparing its size to a grapefruit. The object was observed to stop, start, and perform right-hand climbs. Radar contact was maintained by Tonopah and Winnemucca AFS. The report includes technical data, such as atmospheric conditions and the specific coordinates of the radar sites. The official conclusion reached by the Foreign Technology Division was that the visual sighting was likely the star Capella, while the radar returns were attributed to a possible atmospheric 'bubble' or weather phenomenon. Despite the investigation, the Assistant UFO Officer for the base, 1st Lt Howard C. Austin, noted that he was unable to find facts to support the hypothesis that the object was a known aircraft. The document includes internal correspondence between Major Hector Quintanilla, Jr. and the Electronics Directorate regarding the analysis of the radar data.
