This document is an Air Intelligence Information Report (Report No. II-57-52w) dated August 7, 1952, concerning a sighting of an unidentified flying object over San Francisco, California. The incident occurred on August 4, 1952, at 1045 Pacific Daylight Time. The primary witness was a civilian woman who described the object as a 'large dial-like object.' The report was prepared by 2nd Lt. James W. Westbrook of the 28th Air Division at Hamilton Air Force Base and reviewed by Captain Orville B. Bixel, the Director of Intelligence. The report notes that the weather conditions in the area were clear, with specific wind data provided for 10,000 and 20,000 feet. The investigation into the sighting yielded negative results regarding physical evidence, radar contact, or the presence of known aircraft in the vicinity. The official conclusion reached by the preparing officer is that there is insufficient information available to determine the identity of the object. The document is marked as a 'very incomplete' record, designated as case 112, and was distributed to the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
