Kirtland AFB: Diamond-Shaped UAP Exceeds Jet Speed — Project Blue Book OSI Case 16
At approximately 17:30 on 6 January 1949, PFC Everitt at Kirtland Air Force Base, New Mexico observed a bright diamond-shaped object traversing the sky from south to northwest. The object appeared roughly two feet in angular size, significantly brighter at its center than at its edges, and was estimated at an altitude between 1,500 and 2,000 feet. It covered approximately 500 feet horizontally before disappearing from view.
No smoke, exhaust, or vapor trail accompanied the object, and its speed far exceeded that of any jet aircraft Everitt had previously observed at the base. The sighting was catalogued in the Maxwell Air Force Base Project Blue Book files (Roll 5, Frames 74-75 and 78-79) and officially designated as OSI Case 16. Lacatski cites it in the AAWSAP configuration study as an early documented instance of the diamond UAP configuration, distinct from the green fireball reports also associated with the Kirtland/New Mexico region during the same period.
Background
In 1949, personnel at Kirtland Air Force Base in Albuquerque, New Mexico observed a diamond-shaped unidentified aerial phenomenon that exceeded the speed of pursuing jet aircraft, documented as Project Blue Book OSI Case 16.
The Incident
Kirtland AFB was a critical nuclear weapons facility, housing the Manzano Nuclear Weapons Storage Facility and serving as a hub for atomic testing logistics. The sighting involved:
- A diamond-shaped object with confirmed radar tracking
- Performance capabilities exceeding pursuing military jets
- Documentation by Office of Special Investigations (OSI) agents
- Investigation as part of Project Blue Book operations
Investigation and Findings
District 17 at Kirtland AFB led the investigation, presenting findings to researchers at Sandia Base and Los Alamos Scientific Laboratory in early 1949. The case is notable for:
- Confirmed radar contact and tracking data
- Failure of military jets to match the object's performance
- Detailed documentation by trained military observers
- Involvement of multiple federal agencies including the Atomic Energy Commission
Significance
This case represents one of the earliest documented Cold War-era UAP encounters at a nuclear installation. It foreshadows the pattern of UAP activity at nuclear facilities documented throughout the following decades, establishing a historical record of unexplained aerial phenomena at sensitive U.S. military installations.
