Incident #275 Sighting Report — Los Alamos, New Mexico, 3 March 1949

This document is an official sighting report, designated as Incident Number 275, concerning an unidentified aerial object observed at Los Alamos, New Mexico, on March 3, 1949. The report was authored by Sgt. D. M. Rickard and details an observation made at 0159 hours by an Atomic Energy Security Service (AESS) inspector stationed at Station 101. The witness, who was sitting in a chair facing east and conversing with a Lt. Buckley, reported seeing a bright green, self-luminous light falling almost straight down in an east-north-east direction relative to their position. The light remained bright throughout the duration of the observation. The report notes that the weather conditions at the time included broken clouds at 25,000 feet. The document includes a standard guide to investigation for unidentified aerial objects, which remains largely incomplete regarding specific technical details such as size, speed, and duration, marked as 'N/S' (not stated). The report concludes with a handwritten annotation identifying the object as an 'Astro (meteor)'. The document also includes a formal statement from the observer and identifies Lt. Earle D. Hightower, Operations Officer of the Protective Force, as a recipient or relevant authority. The report emphasizes the need for a complete background investigation of the observer for employment purposes.
