Ringlinie
In the spring of 1947, Northwest began stationing employees at Haneda Airport in Tokyo, flying them from the United States via Alaska on its Great Circle route. On July 15, 1947, Northwest was the first airline to begin direct service between the United States and Japan, using a Douglas DC-4 airliner named "The Manila". (All pre-war airline service to the Orient had been via Hawaii and the Philippines.) The flight to Japan originated at Wold-Chamberlain Field in Minneapolis and stopped at Blatchford Field in Edmonton, Elmendorf AFB in Anchorage, and Shemya AAF in the western Aleutian Islands. The flight continued from Tokyo to Lunghwa Airport in Shanghai and then to Nichols Field at Manila.
