Unidentified Flying Object Report — Danville, California, 2 August 1955

This document consists of an Air Intelligence Information Report (IFR 7-55) regarding an Unidentified Flying Object sighting that occurred on 2 August 1955 in Danville, California. The report was filed by Captain Donald W. Galvin of the 28th Air Division (Defense) at Hamilton Air Force Base. The primary witness was a retired U.S. Army Colonel and his wife, who observed the object from a Ground Observer Corps (GOC) post. The witness described the object as bulbous and ruby-colored, with a redder edge and a red-orange center. The object was observed for less than one minute, during which time it faded from view after passing through a 40-degree arc. The weather conditions were reported as CAVU (Ceiling and Visibility Unlimited). The report notes that the witness used 7x50 Navy binoculars during the observation. The official conclusion reached by the Director of Intelligence for the 28th Air Division was that the sighting provided insufficient data for a formal evaluation, though it was noted as a possible meteor or aircraft. The file also includes a Project 10073 record card summarizing these details and a follow-up letter dated 24 February 1958 from Major Lawrence J. Tacker of the USAF Office of Information Services, acknowledging a letter from the witness regarding the incident. Major Tacker noted that it was difficult to properly investigate an incident nearly three years after the fact, but confirmed the report would be added to their files.
