Project 10073 Record Card and Related Correspondence — Lowry AFB, Colorado, 9 July 1954

This document consists of a Project 10073 record card and associated correspondence regarding a sighting of unidentified objects over Lowry Air Force Base, Colorado, on 9 July 1954. At approximately 1430 hours, multiple witnesses, including senior pilots and flight dispatchers from United Air Lines, observed four to five 'shining specks' at an estimated altitude of 50,000 feet. The witnesses described the objects as triangular in shape, capable of hovering for extended periods, and moving in a northeasterly direction. The observation lasted for approximately 35 minutes. Special agents from the 14th OSI District conducted interviews with witnesses and personnel from the 3933rd Radar Bomb Squadron. While the witnesses were confident in their observations, the radar units reported no unusual activity, although they noted that a B-36 aircraft was in the area conducting radar and radio jamming tests. The report also notes that a local radio station broadcasted information about a military exercise, Operation CHECK POINT, occurring in the vicinity, which involved F-86 aircraft at high altitudes. The official conclusion recorded on the project card suggests the objects were likely a 'cluster balloon observation' but ultimately deemed the data insufficient for a definitive evaluation.
