The Post Office Department got commercial aviation off the ground in 1926, when it contracted for private firms to carry the mail. By 1976, commercial flight was the principal means of inter-city passenger travel.
U.S. #1684 commemorates the 50th anniversary of the first contract airmail flights. On February 15, 1926, the first flight left Dearborn, Michigan, for Cleveland, Ohio. The second flight occurred on April 6, 1926, on a route from Pasco, Washington, to Elko, Nevada.
