The B-1 mail plane was the first Boeing-designed commercial aircraft. It first flew on Dec. 27, 1919. Eddie Hubbard, pictured here, flew this one from 1920 to 1927 on the first regularly scheduled international air mail route between Seattle and Victoria, B.C. The plane could carry two passengers plus mail and cargo. After seven years of service without losing a single piece of mail, the B-1 was retired from air mail service in 1927. The plane now hangs on exhibit at the Museum of History & Industry, in Seattle. Photo: Museum Of History & Industry (image No. 1980.6877.176)
