Report of Investigation: Sighting of Flight of Unidentified Aerial Objects over Los Alamos, New Mexico, 22 July 1952

This document is a formal investigation report regarding a sighting of unidentified aerial objects over Los Alamos, New Mexico, on July 22, 1952. The investigation was initiated by the District Commander following reports from Don R. Wiens, a tower operator at the Los Alamos Air Port, and other personnel including pilots from Carco Air Service. Between 1050 and 1115 hours, witnesses observed approximately eight round or elliptical objects that appeared to be aluminum or bright metallic in color. The objects were initially seen hovering directly overhead before moving in a south to southwest direction. Witnesses described the objects as having a very high rate of speed and performing erratic maneuvers, including sudden 90-degree turns and reversing direction, which were described as being tighter than any maneuver possible for jet aircraft. The objects were observed to be oscillating in a manner that caught the reflection of the sun. The witnesses noted that the objects lacked wings or tail surfaces and appeared to be under intelligent control. Due to the extreme speed and behavior, the observers concluded that the objects were not balloons. The sighting lasted approximately 25 minutes, though not continuously, and was primarily viewed through binoculars. The report includes statements from the witnesses and confirms that the weather conditions were clear, with some cumulus clouds over the mountains to the west. The investigation was conducted by S/A Richard S. Secord and was classified as confidential at the time of issuance on August 30, 1952. The reliability of the primary observer, Don R. Wiens, was noted as excellent by the investigating authorities.
