Correspondence Regarding UFO Sighting in Los Lunas, New Mexico, May 1967

This document collection details a series of communications between a civilian witness in Los Lunas, New Mexico, and the United States Air Force regarding a UFO sighting on May 10, 1967. The witness reported observing a large, bright yellow sphere descending from the Sandia Mountains to tree-top level, which then changed color to orange and red before departing in a straight line toward Albuquerque. The Air Force, through the Safety Office at Kirtland Air Force Base, investigated the report and concluded that the sighting was caused by an Air Force helicopter operating high-powered searchlights in an area with significant dust and blowing sand. The witness formally rejected this explanation, asserting that the object she saw was not a directed beam of light but a distinct, large sphere that did not blink or change colors in the manner of a searchlight. The correspondence includes internal Air Force message traffic (AFIN: 53043) that references multiple sightings in the region, including reports from Las Vegas, Nevada, and Boulder City, Nevada, which were also investigated under Project 10073. These reports were eventually attributed to the planet Venus or other conventional explanations. The documents highlight the tension between civilian reports of anomalous aerial phenomena and the military's efforts to provide conventional explanations, such as helicopter operations or astronomical events.
