CNAC pilots made a key contribution to India-China flight operations. Between 1942 and 1945, the Chinese received 100 transport aircraft from the United States: 77 C-47s and 23 C-46s. Of the eventual 776,532 gross tons and approximately 650,000 net tons transported over the Hump, CNAC pilots accounted for 75,000 tons (about 12%). The India-China airlift continued beyond the end of the war. The final missions of the ICD, made after most of its attached organizations had departed, were the transporting of 47,000 U.S. personnel west over The Hump from China to Karachi for return to the United States.
