CIA-UAP-D023, Briefing Notes for Mr. Walter Elder

According to the U.S. Department of War release, this two-page document contains briefing material prepared for Mr. Walter N. Elder, Executive Assistant to the Director of the CIA, regarding an incident allegedly involving unidentified aircraft in the vicinity of Puerto Rico on 19 November 1964 (with related activity noted on 16, 18, and 24 November). The briefing states that a radar system aboard the guided missile destroyer USS Gyatt detected a contact tracking in excess of 3,800 knots over a period of 21 minutes, and that on 24 November the Atlantic Fleet Weapons Range held a high-speed, high-altitude target that pulled away rapidly from a Crusader aircraft flying at Mach 0.99 at 45,000 feet. An F-8 Crusader pilot on the night of the 19th observed the UFO in full moonlight with good visibility, identifying it as a delta-shaped object about the size of a jet fighter and estimating its speed in excess of Mach 3; USS Gyatt confirmed tracking with motion pictures of its radar scope. The Office of Naval Intelligence (ONI) reportedly had no further information and was asked to notify the CIA of similar future incidents. The companion document CIA-UAP-D022 covers the same subject.
