Unidentified Flying Object Reported Near Puerto Rico 1965

Summary

CIA-UAP-D022 is a Central Intelligence Agency memorandum, handled under BYEMAN/OXCART controls, summarizing unidentified flying objects reported near Puerto Rico in late 1965. The text describes radar contacts on 19 November, when an object appeared on radar and closed on a fighter, and a high-speed, high-altitude target on 24 November at the Atlantic Fleet Weapons Range while a Crusader aircraft flew at Mach 0.99 and 45,000 feet. A pilot identified the object as a Delta-shaped object about the size of a jet fighter and estimated its speed at more than Mach 3. Photographs of the radar scope presentation were analyzed, and the memo concludes the object was probably a delta-wing aircraft of a type with sufficient performance characteristics.
