PROJECT 10073 RECORD CARD — Holloman AFB, 24 March 1951

This document is a Project 10073 record card detailing a sighting incident that occurred on March 24, 1951, at Holloman Air Force Base in New Mexico. The incident involved an unidentified object captured by a tracking camera between 0555 and 0600 MST. The photograph was taken during the course of routine meteor studies and triangulation efforts conducted at the base. Despite the photographic evidence, the record indicates that the case was ultimately classified as having insufficient data for a formal analysis. The investigating authorities noted that critical information was missing, specifically the duration of the observation, the direction of the object's flight, and whether the object was observed visually by any personnel. The document includes an enclosure, labeled Enclosure B, which provides technical data regarding the camera's settings and the angles subtended by the object, noting a major axis of 18.6 and a minor axis of 20.6. The record card concludes that because the necessary contextual data was absent, no definitive explanation for the object could be determined. The document was later downgraded and declassified in accordance with Department of Defense Directive 5200.10.
