Project 10073 Record Cards and Related Correspondence — San Antonio, Texas, November 1957

This document collection consists of a series of Project 10073 record cards and associated military teletype reports documenting multiple UFO sightings in the San Antonio, Texas area during November 1957. The reports detail various civilian observations, including an oval-shaped object approximately 60 feet long that allegedly caused a car's engine and lights to fail, a cluster of round objects with fiery trails, and a small, pale yellow object observed for 30 minutes. Military investigators from the 741st ACWRON at Lackland Air Force Base consistently evaluated these reports as having insufficient data, often attributing the sightings to overactive imaginations, meteors, or weather balloons. The reports frequently note that the weather conditions in the area—characterized by rain, fog, and low ceilings—would have made accurate observation of astronomical bodies or other phenomena difficult. The documentation highlights the military's skepticism, with investigators frequently noting inconsistencies in the witnesses' accounts, such as errors in time and direction. Several reports explicitly state that no unusual activity was detected on radar, further leading the Air Technical Intelligence Center to conclude that the reports were unreliable or lacked sufficient evidence for a definitive explanation.
