Boeing 367-80 Refuelling B-47 Stratojet | Boeing Classics
The Model 367-80 was the prototype for the 707 passenger jet and the KC-135 jet tanker, Because the prototype was constructed to sell first as a military-tanker transport, it had few windows and no seats, but had two large cargo doors. A week after its first flight, the Air Force ordered 29 tanker versions, the KC-135.
