Colonial Western Airways operated the Sikorsky S-38 between Albany and Cleveland. In 1928 it became a division of the Colonial Airways Corporation holding, together with Colonial Air Transport and Canadian Colonial Airways, but all three airlines continued to operate under their own names. Colonial Western was fully merged into American Airways in March 1931. That same month this amphibian was used for rescue work following the sinking of an old sealing ship, SS Viking, off the Horse Islands, Newfoundland, during a movie shoot. The famous Bernt Balchen piloted the aircraft after speeding to Boston by train. Photo by: Leslie Jones / Boston Public Library
