Project 10073 Record Cards and Correspondence — White Sands Proving Ground, October 1951

This document collection comprises a series of Project 10073 record cards and associated correspondence from the Headquarters Fourth Army, dated October 1951. The records detail multiple sightings of unidentified aerial phenomena reported by military personnel stationed at the White Sands Proving Ground in New Mexico on the night of 2 October 1951. Witnesses, including members of the 4119th ASU, reported observing objects with varying characteristics, such as amber, red, and orange-blue colors, and shapes described as rocket-like, oblong, or square. The objects were observed moving at high speeds, with some witnesses estimating them to be several times faster than a rocket. Several reports noted the presence of a halo around the objects. Despite the varied descriptions, the official evaluation for these incidents consistently categorized the phenomena as 'Astro' or 'Meteor' sightings. The correspondence from Colonel George A. A. Jones, AC of S, G-2, indicates that these reports were forwarded to the Air Material Command at Wright-Patterson Air Force Base for further information and action. The documents include detailed 'Guide to Investigation' forms for several witnesses, capturing specific data points such as time, location, duration, and physical characteristics of the objects. The weather conditions were consistently reported as clear with wind, providing good visibility for the observers. The records reflect the standard military procedure for documenting and evaluating aerial sightings during this period, with a clear emphasis on identifying potential astronomical causes for the reported phenomena.
