Project 10073 Record Card and Air Intelligence Information Report — Phoenix, Arizona, 5 May 1952

This document consists of a collection of reports and correspondence regarding a UFO sighting that occurred on May 5, 1952, in Phoenix, Arizona. The primary record is a Project 10073 record card, supplemented by an Air Intelligence Information Report (AF Form 112) and related staff messages. A male civilian witness reported observing an object in the sky at 2200 hours local time. The witness described the object as having an iridescent, bluish-green light, which he compared to the arc of an electric welder. The object was observed for approximately two seconds while it was moving in a northeasterly direction at an altitude of roughly 10,000 feet, ascending at a 10-degree angle. The witness reported that the object made no sound and was traveling at a speed estimated to be in excess of 1,000 miles per hour. The reporting officer, 2d Lt. [illegible], noted that the object's aerodynamic features, propulsion, and maneuverability could not be determined, and that there was no physical evidence or photographs available. The report explicitly states that the observer's reliability could not be judged. Weather conditions at the time were reported as clear with visibility over 15 miles. The document includes administrative correspondence from the 34th Air Division (Defense) and the Air Technical Intelligence Center, confirming that the report was submitted in compliance with Air Force Letter 200-5. The final assessment within the status report suggests that the description is similar to a meteor or fireball. The documents are marked as restricted and include instructions for downgrading and declassification after 12 years, in accordance with DOD Directive 5200.10.
