Boeing 707
Canadian Air Force Boeing 13702 (the military equivalent of the Boeing 707 transport).
The Boeing 707 is a four engined commercial passenger jet aircraft developed by Boeing in the early 1950s. Although it was not the first commercial jetliner in service (that distinction belongs to the De Havilland Comet), it was the first one to be commercially successful, and is credited by many as ushering in the "Jet Age"
It was originally built for the USAF as an air-tanker with the designation C-135. The fuselage is 6 inches wider than that of the C-135.
The Boeing 707 was originally fitted with four turbojets, but later versions came equipped with four turbofans, the latter being quieter, more powerful and fuel efficient.
Production of the 707 continued until 1991, and although it is no longer employed by major US Airlines, many can still be found in service with smaller non-US airlines, charter services and air cargo operations.
The first two aircraft built to serve as Air Force One were custom-built Boeing 707s.
