Project 10073 Record Card — San Antonio, Texas, 8 March 1954

This document contains a Project 10073 record card and associated military correspondence regarding a UFO sighting in San Antonio, Texas, on March 8, 1954. The primary report details a sighting by a military officer and several civilians who observed a group of 10 to 20 high-intensity, fluorescent white lights arranged in a crescent shape. The objects were estimated to be at an altitude between 10,000 and 20,000 feet, traveling at approximately 1,500 mph in a straight line from south to east. The witnesses reported a bluish haze surrounding the objects and noted that there was no sound. The observation lasted approximately three seconds before the objects were obscured by trees. The official conclusion recorded on the card is that the phenomenon was a meteor breaking up, although the reporting officer noted it as a 'possible case of sighting UNK.' The document also includes a press compilation titled 'Saucer Marginalia,' which reviews other sightings, including one by John H. Stewart in Cincinnati, Ohio, on March 9, 1954. This secondary report describes a pulsating, bluish-white light that hovered over a General Electric plant before accelerating and changing color. The compilation further references skeptical commentary from experts such as Professor J. Ackeret and Dr. Roy K. Marshall, while contrasting these views with reports from astronomers like Dr. Clyde Tombaugh, who witnessed an oval-shaped object in 1948. The military correspondence confirms that at the time of the San Antonio sighting, a B-50 and a C-29 aircraft were in the area, but their crews reported nothing unusual.
