Project 10073 Record — Incident #400, Sacramento, California, 15 July 1949

This document is a formal report regarding an aerial observation made on 15 July 1949 at approximately 1420 PST in the vicinity of McClellan Air Force Base, Sacramento, California. The witness, a civilian Air Force Police officer, reported seeing a single object that appeared as a mirror reflecting light. The object was described as having a wobbling motion and was observed for only a few seconds. According to the witness, the object was traveling in a northeasterly direction at a speed described as being significantly faster than any jet aircraft previously observed. The altitude of the object was estimated to be twice that of two jet-propelled aircraft that were flying in the opposite direction at the time of the sighting. The report was prepared by 1st Lt. Joseph Moore of the Intelligence Section at the Sacramento Air Materiel Area. In his assessment, Lt. Moore noted that the information could not be evaluated at the local installation level, but he emphasized that the witness was considered reliable and not prone to exaggeration, suggesting that the account was accurately relayed. The document includes a project record sheet, a formal memorandum to the Commanding General of the Air Materiel Command at Wright-Patterson Air Force Base, and an incident report form. The official conclusion recorded on the project record is 'Astro (METEOR)'.
