Project 10073 Record Card — Lackland AFB, Texas, 18 October 1957

This document consists of a Project 10073 record card and an associated teletype report regarding an Unidentified Aerial Phenomena (UFOB) sighting that occurred on 18 October 1957 at Lackland Air Force Base, Texas. At 1124Z, personnel from the 741st AC/W Squadron, including Captain David B. Stidham Jr., Staff Sergeant Edwin L. Davis, and Donald E. Wiley, observed a single, round, white glowing object. The witnesses described the object as appearing to be the size of a pin held at arm's length, moving at extreme speed at a very high altitude. The object traveled in a straight line heading south for a duration of 30 to 45 seconds before disappearing into clouds. The observers noted that the object became increasingly difficult to see due to the distance it had traveled away from them. The report explicitly states that the observers were looking for a satellite that was supposed to cross over San Antonio at the time. The official conclusion reached by the evaluating authorities was that the sighting was likely caused by the rocket that launched a Russian satellite. Handwritten notes on the document suggest it was a 'possible 2nd stage of Soviet rocket' and mention that the report was found in the 1956 file, though the incident date is clearly 1957.
