Project 10073 Record Cards and Related Reports

This document contains a series of Project 10073 record cards and associated teletype reports detailing three separate UFO sightings in the San Antonio, Texas area during October 1957. The first incident, occurring on October 5, involved a cigar-shaped aluminum object described as the size of a fountain pen at arm's length. The witness reported hearing jet noise, leading investigators to conclude the object was likely an aircraft, noting that modern 100-series wing designs often make only the fuselage visible. The second incident, on October 8, involved a round red object the size of a pinhead, observed by a Sergeant First Class at Fort Sam Houston. This object was in sight for two to three minutes and moved from south to northwest. The final report, dated October 15, describes two white, nickel-sized objects in close formation that remained stationary before moving slowly northwest and fading. Radar checks for all incidents yielded no unusual contacts. The official evaluations consistently lean toward conventional explanations, including aircraft, weather mirages, or balloons, with investigators noting that the duration and characteristics of the sightings were consistent with these mundane causes.
