The Boeing 367-80, known simply as the Dash 80, is an American quadjet prototype aircraft built by Boeing to demonstrate the advantages of jet propulsion for commercial aviation. It served as basis for the design of the KC-135 tanker and the 707 airliner.
The Dash 80 first flew in 1954, less than two years from project launch. Its US$16 million cost (equivalent to $152 million today) was an enormous risk for Boeing, which at the time had no committed customers. Only one example was built, which has been preserved and is currently on public display at the Udvar-Hazy Center in Virginia.
By the late 1940s two developments encouraged Boeing to begin considering building a passenger jet. The first was the maiden flight in 1947 of the B-47 Stratojet. The second was the maiden flight in 1949 of the world’s first jet airliner, the de Havilland Comet. Boeing President Bill Allen led a company delegation to the UK in summer 1950, where they saw the Comet fly at the Farnborough Airshow, and also visited the de Havilland factory at Hatfield, Hertfordshire where the Comets were being built. Boeing felt it had mastered the swept wing and podded engines which it saw as key technologies that would enable it to improve on the Comet.

As part of the Dash 80’s demonstration program, Bill Allen invited representatives of the Aircraft Industries Association (AIA) and International Air Transport Association (IATA) to the Seattle’s 1955 Seafair and Gold Cup Hydroplane Races held on Lake Washington on August 6, 1955. The Dash 80 was scheduled to perform a simple flyover, but Boeing test pilot Alvin “Tex” Johnston instead performed two barrel rolls to show off the jet airliner.
The next day, Allen summoned Johnston to his office and told him not to perform such a maneuver again, to which Johnston replied that he was simply “selling airplanes” and asserted that doing so was completely safe.

After 2,350 hours and 1,691 flights the aircraft was withdrawn from use in 1969 and placed in storage. On May 26, 1972 Boeing donated the 367-80 to the Smithsonian Air and Space Museum, which had designated it one of the 12 most significant aircraft of all time. For the next 18 years the aircraft was stored at a “desert boneyard” now called the 309th Aerospace Maintenance and Regeneration Group (AMARG) at Davis-Monthan Air Force Base near Tucson, Arizona before being retrieved by Boeing in 1990 for restoration. The Dash 80’s final flight was to Dulles International Airport near Washington, D.C. on August 27, 2003. Repainted to its original yellow and brown Boeing livery, it was put on display at the Steven F. Udvar-Hazy Center, an annex of the Smithsonian Institution’s National Air and Space Museum, located adjacent to Dulles Airport in Chantilly, Virginia.
The B-29 was the progenitor of a series of Boeing-built bombers, transports, tankers, reconnaissance aircraft, and trainers. The re-engined B-50 Superfortress became the first aircraft to fly around the world non-stop during a 94-hour flight in 1949. The Boeing C-97 Stratofreighter airlifter, which was first flown in 1944, was followed in 1947 by its commercial airliner variant,
