Passenger Service. The China National Air Service route from 
Calcutta to Chungking is being strengthened by the addition of
 American transport planes. This service consists of passenger airplanes
 operating on a commercial basis. It is essential that we assist in
 maintaining its continued operation in order to assure direct connections
 between Chungking and Calcutta. We are furnishing them with some
 twenty to twenty-five airplanes. This service, however, does not
add in any way to the cargo capacity now carried over the Burma Road.
