Project 10073 Record Cards and Related Correspondence — Ladd AFB, Alaska, December 1952

This document is a collection of records and correspondence regarding unidentified aerial phenomena (UAP) sightings in the vicinity of Ladd Air Force Base, Alaska, and Greenland during December 1952. The primary report concerns a sighting on December 9, 1952, by an F-94A crew (1st Lt. Donald A. Dickman and 1st Lt. Thomas W. Davies). The crew observed a white, oval-shaped light that appeared to be the size of a landing light at a distance of 0.5 to 1 mile. The object exhibited erratic flight characteristics, including changing color from white to red as it gained altitude, and eventually descending in a manner described as resembling a falling star or a helicopter. The object was not audible, and no propulsion system was observed. The weather was clear with VFR conditions and a temperature of -22 degrees. The radar observer, Lt. Davies, maintained visual contact throughout the landing maneuvers. Subsequent investigation by the 5001st Composite Wing and the Air Technical Intelligence Center (ATIC) noted discrepancies in the initial reports and requested further documentation, including flight path sketches and weather data. The document also includes reports of contrail sightings in Greenland, which were evaluated as potentially being from hostile reconnaissance aircraft, though later assessments suggested they might have been caused by friendly F-86 aircraft on classified missions. The records highlight the challenges of evaluating these sightings due to conflicting witness statements and the lack of physical evidence. The military authorities emphasized the need for accurate reporting in accordance with established procedures, such as the CIRVIS reporting system, and expressed concern over the improper use of 'flash' priority for messages that were later found to be based on inaccurate data.
