Project 10073 Record Card and Correspondence — San Antonio, Texas, 26 August 1951

This document comprises a collection of records regarding an Unidentified Aerial Phenomena (UAP) sighting that occurred on 26 August 1951 in San Antonio, Texas. The primary record is a Project 10073 Record Card, which documents the observation of a single, dark, large object at a very high altitude. The witness, identified as a retired Army officer formerly with the 28th Infantry Division, reported that the object moved at a high rate of speed in a northwesterly direction for approximately ten seconds. The witness explicitly noted that the object did not resemble a conventional aircraft and traveled too fast for such a craft. The weather conditions at the time were reported as very clear with no clouds. The report includes internal military correspondence routing the sighting from the Headquarters Fourth Army to the Fourteenth Air Force Liaison Officer at Brooks Air Force Base, and subsequently to the Air Materiel Command at Wright-Patterson Air Force Base. The correspondence highlights that the Fourth Army assigned no security classification to the report, though it was later processed under the reporting requirements for 'Unconventional Aircraft' established by ConAC Letter 200-1. Despite the witness's detailed account, the official conclusion recorded on the Project 10073 card is that the object was evaluated as a meteor. The documentation provides a clear view of the administrative process for handling UAP reports in the early 1950s, including the involvement of intelligence officers and the formal reporting chain between regional military commands and the Air Materiel Command.
