This aircraft was lost in the South China Sea on 5 June 1968. CIA pilot, Jack Weeks was flying what was to be the last operational A-12 mission from Kadena AB, Okinawa. The loss was due to an inflight emergency and the pilot did not survive. Once again the official news release identified the lost aircraft as an SR-71 and security was maintained. A few days later the two remaining planes on Okinawa flew to the U.S. and were stored with the remainder of the OXCART (CIA) family.
