On July 15, 1954, a graceful, swept-winged aircraft, bedecked in brown and yellow paint and powered by four revolutionary new engines, first took to the sky above Seattle. Built by the Boeing Aircraft Company, the 367-80, better known as the Dash 80, would come to revolutionize commercial air transportation when its developed version entered service as the famous Boeing 707, America's first jet airliner.
