What did the declassified documents reveal?

This episode presents a declassified United States Navy memorandum dated August twenty‑six, nineteen‑sixty‑seven. The memorandum was prepared for the President and details the shoot‑down of three Navy A‑6A attack aircraft over the People’s Republic of China. The document is notable because it contains the first unclassified account of the incident that was offered for possible press release. The memorandum was released to the public through The Black Vault, the online repository that publishes government documents obtained via Freedom of Information Act requests. The file is available in the Black Vault’s digital collection under the identifier CI01827, with the full text hosted at archive.org.

All three employed evasive maneuvers in reaction to the missiles and heavy anti‑aircraft fire. Severe turbulence was also encountered during the egress. During one evasive maneuver, one of the three A‑6As—the surviving aircraft—lost sight of the other two. He then saw them join formation about ten miles east of Kep Airfield. The third plane remained several miles south of the first two. Preliminary reports indicating that the third plane had seen MiGs over North Vietnam were not substantiated by the later debriefing of the surviving pilot. It is believed that the surviving plane also briefly penetrated into Chinese airspace, although the Department of Defense has not suggested this publicly. Three border warnings were issued to the aircraft by the USS CONSTELLATION prior to the violation and another two warnings were issued by an E‑2A aircraft. These warnings were not heard by the surviving pilot and it is assumed they were not received by…
