Official Conclusion

Unresolved; ONI has no further information and has requested notification of similar future incidents.

Official Description

This document contains briefing material prepared for Mr. Walter N. Elder, Executive Assistant to the Director of the Central Intelligence Agency (CIA), regarding a November 19, 1964, incident allegedly involving unidentified aircraft in the vicinity of Puerto Rico. The previous entry in this collection, CIA-UAP-D022, contains CIA memoranda on the same subject matter. The briefing includes additional details regarding that incident, including a characterization of the meteorological conditions and sensing capabilities of nearby U.S. military collection systems. The briefing states that a radar system aboard USS Gyatt, a guided missile destroyer operating in the vicinity, detected a contact tracking more than 3,800 knots (approximately 4,373 mph) over a period of 21 minutes. The briefing contains visual estimates regarding the phenomenon’s apparent capabilities from the pilot of an F-8 Crusader who was present during the incident.

Key Findings

• →The USS Gyatt's radar tracked an unidentified object at speeds in excess of 3,800 knots (approximately Mach 3+) for twenty-one minutes on November 19.
• →An F-8 Crusader pilot visually identified the UFO in full moonlight as a delta-shaped object approximately the size of a jet fighter.
• →When the Crusader pilot selected afterburner to close on the object at approximately five miles distance, the object accelerated at extremely high speed in a 20-degree climb and pulled away rapidly.
• →On November 24, the Atlantic Fleet Weapons Range tracked another high-speed, high-altitude target that pulled away from a Crusader aircraft flying at Mach 0.99 at 45,000 feet.
• →The USS Gyatt confirmed radar tracks with motion pictures of the radar scope presentation, and the pilot estimated the object's speed to be in excess of Mach 3.
