Project 10073 Record Card and Worksheets — Kirtland AFB, 20 August 1952

This document consists of a collection of Project 10073 record cards and worksheets detailing a UAP sighting that occurred on August 20, 1952, in the vicinity of Kirtland Air Force Base, New Mexico. The report documents two distinct observations occurring around 0300Z. The first report, filed under reference FLYOBRPT 1429, describes a single, triangular-shaped, silver object observed by a civilian carpenter. The witness reported that the object traveled from west to east for approximately three minutes before disappearing behind a tree line. The witness noted that the object had no sound and no visible propulsion trail. A second report, FLYOBRPT 1434, describes a similar sighting by a USAF pilot on flying status, who observed a triangular, silver object overhead for approximately fifteen seconds. This witness reported seeing ten to twelve lights on the object, which they believed to be exhaust, before it made an orbit and disappeared into the clouds. Both reports were processed by the 34th Air Division at Kirtland AFB and forwarded to the Air Technical Intelligence Center (ATIC). The official conclusion for the incident, as noted on the Project 10073 record card, is that the object was a weather balloon released from Kirtland AFB at 0300Z on the same date. The documentation includes weather data sheets for the area, confirming the atmospheric conditions at the time of the sighting, and standard project worksheets used for evaluating astronomical and aircraft data. The reports emphasize the lack of radar contact and the absence of any sound associated with the object in the first report, while the second report provides more specific details regarding the lights observed on the craft. The file is marked as 'Cy 1' and contains multiple iterations of the report forms, reflecting the administrative process of the Air Force's investigation into unidentified aerial phenomena during this period.
