Briefing Notes for Mr. Walter Elder
🏛️ CIA
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.

Unidentified Flying Object Reported near Puerto Rico, 1965
CIA
This file contains Central Intelligence Agency (CIA) memoranda exchanged between the Assistant Director for Special Activities (AD/SA) and the Assistant Director for Scientific Intelligence (AD/SI) regarding an incident allegedly involving unidentified aircraft in the vicinity of Puerto Rico. The AD/SI was then-responsible for analyzing foreign scientific advancements and technological threats, such as Soviet nuclear, chemical, and ballistic missile capabilities. The AD/SA managed the CIA’s classified overhead reconnaissance operations, including the deployment of advanced aircraft like the U-2 and A-12 OXCART. Together, these offices ensured the United States could both gather critical intelligence over contested territories and accurately evaluate the technical capabilities of foreign adversaries during the Cold War. The memoranda refer to an incident on November 19, 1964, in which a U.S. Naval aviator described observing an unidentified object as “delta-shaped, about the size of a jet fighter.” The pilot visually estimated the object’s velocity as Mach 3 (approximately 2,200 mph). A corresponding track from an AN/SPS-49 radar system aboard a U.S. Navy guided missile destroyer in the area, USS Gyatt, measured the object’s speed at 3,800 knots (approximately 4,373 mph). The memoranda indicate that, in the opinion of the AD/SI, the object was conceivably associated with foreign intelligence gathering activities, citing active missile testing within the AFWR, or Atlantic Fleet Weapons Range, as being an attractive reconnaissance target. The AD/SA and AD/SI also ruled out domestic experimental aircraft, such as the YF-12A OXCART, as a potential attribution.
