UFO Report - Glendale, Arizona - 1 May 1960

This document is a formal UFO sighting report filed by the 4510th Combat Crew Training Wing at Luke Air Force Base, Arizona, regarding an incident on 1 May 1960. The report details the account of a 38-year-old male witness in Glendale, Arizona, who observed a round, white object, approximately the size of a quarter, while watching a strong 'dust devil' in his backyard. The witness reported that the object crossed the path of the dust devil and continued on a straight, high-speed course before fading from sight. The observation lasted no more than 15 seconds. The witness, who had served in the Army during World War II, expressed initial hesitation in reporting the event due to concerns about military ridicule. The investigating officer, T/Sgt Johnie J. Britton, noted that the witness appeared to be of above-average intelligence and was cooperative during the interview. The report includes detailed meteorological data from the 25th Weather Squadron, noting a strong temperature inversion between 11,000 and 15,000 feet in the Phoenix area at the time of the sighting. Radar stations in the area reported no unusual activity. The official preliminary analysis suggests that the witness likely observed a piece of paper caught in the wind, with the temperature inversion potentially causing optical distortions. The sighting was ultimately categorized as having insufficient data for a definitive evaluation, and the reliability of the report was rated as F-3.
