Compilation of Reports on Unidentified Aerial Phenomena, December 1949

This document is a compilation of intelligence reports and correspondence from December 1949 regarding sightings of unidentified aerial phenomena, specifically green fireballs and spherical objects, across New Mexico, Oklahoma, and Louisiana. The reports detail observations made by military personnel and civilians, including a salesman, a Lieutenant Colonel at Sandia Base, and a flight crew of a C-47 aircraft. Witnesses consistently described the objects as bright, luminous, and green or silver in color, often moving at high speeds with the ability to perform rapid maneuvers, such as abrupt stops, descents, and changes in direction. Several reports note that the objects appeared to be spherical or round, with some observers comparing their size to a marble or a half-dollar held at arm's length. Despite the high number of sightings, no physical evidence, such as meteorites or debris, was recovered. Investigations conducted by the 17th District Office of Special Investigations and the Air Materiel Command, often in consultation with Dr. Lincoln LaPaz of the Institute of Meteoritics, concluded that there was no evidence of radar contact or testing devices that could explain the phenomena. The reports emphasize the reliability of the witnesses, who were interviewed by investigators and found to be credible. The document also includes weather data and meteorological assessments, noting that while some sightings occurred during clear conditions, no known celestial phenomena or aircraft could account for the specific characteristics reported. The file concludes with administrative notes regarding the closure of these investigations and the lack of photographic evidence.
