Project 10073 Record Card — Del Rio, Texas, July 1957

This document consists of a Project 10073 record card and associated military correspondence regarding a UFO sighting reported on July 10-11, 1957, near Del Rio, Texas. The witness, identified as a station owner, reported observing a red flashing light that remained stationary before drifting downward and disappearing over the horizon. The observation lasted approximately 35 minutes. The report notes that the witness used binoculars to view the object. Military authorities, including the 741st Aircraft Control and Warning Squadron and the Air Technical Intelligence Center, reviewed the report. The official conclusion reached by the investigators was that the object was likely an astronomical body, such as a star or the planet Mars. The investigators noted that the lack of specific altitude and bearing data made a precise identification difficult, but the fact that the object was observed in the same stationary position on subsequent nights strongly suggested an astronomical origin. The report emphasizes that the area is one of extensive flying training, and while the possibility of an aircraft performing unusual maneuvers was considered, the evidence pointed toward a celestial phenomenon.
