OSI and OSA, we believe; received similar information regarding a UFO in the vicinity of Puerto Rico during period 18-24 November 1964. As you can see by the cable originated by the Commander, Caribbean Sea Frontier, to Commander in Chief Atlantic Fleet, date time group Ol/2048Z December, CINCLANTFLT was informed that UFO identified by CO Ramey as being YF-12A. We think ONI finally convinced, through our efforts, that UFO in fact not YF-12A or similar category Lockheed Aircraft. 2. Navy has provided, at our request, pertinent traffic on this subject, as well as original radar film, Attachment 1, with accompanying prints of same. Request OSI, possibly in conjunction with OEL, evaluate the radar photography to determine if any further information can be gotten through a thorough scientific analysis of the material relative to a high speed, high altitude UFO. 3. Request on completion of OSI study that the attached documents, film and prints be returned to the TCO/BCO/OSA for return to Navy. ....__i ACK C.
