Sighting Report — Albuquerque, New Mexico, 13 December 1953

This document is a formal sighting report filed on December 13, 1953, regarding an unidentified aerial phenomenon observed in Albuquerque, New Mexico. The report, processed under Air Force regulations (specifically referencing AFR 200-2), documents a civilian observation of four round, metallic objects. The witness reported that the objects were changing formation while rising at a high altitude. The duration of the observation was recorded as 45 minutes. The report includes administrative details, such as the time of the incident (2250Z) and the lack of photographic or physical evidence. The evaluating agency, the 4th Air Division at Kirtland Air Force Base, ultimately concluded that the objects were likely balloons, specifically suggesting they were 'pillow or cluster balloons.' Despite this conclusion, the investigating officer noted that the data provided was inadequate to allow for a definitive evaluation. The document also identifies a witness named Forster, whose occupation and reliability were listed as unknown at the time of the report. The report was distributed to the Air Technical Intelligence Center at Wright-Patterson Air Force Base and the Air Defense Command at Ent Air Force Base, Colorado Springs.
