A USAF Special S.E.A. Operational Navigation Chart, sheet SOC-1, mapping the Vietnamese coastline and the adjoining waters of the Gulf of Tonkin and Gulf of Thailand at 1:1,000,000 scale. Printed with terrain relief, elevation data, and overlaid territorial water and air defense identification boundaries, it was the kind of chart aircrews used for flight planning, target orientation, and search-and-rescue — this example preserved in the collection of Capt. Bob Karre, USAF.
