The Boeing 367-80 or Dash 80 as it was called within Boeing is an American prototype jet transport built to demonstrate the advantages of jet aircraft for passenger transport over piston-engine airliners. The Dash 80 is considered to have been the prototype for the KC-135 Stratotanker aerial refuelling tanker and the B707 airliner. It was built in less than two years from project launch in 1952 to rollout on May 14 1954 for a cost of US$16 million.
