The 707 is a four-engine commercial passenger jet airliner developed by Boeing in the early 1950s. Boeing delivered a total of 1,010 Boeing 707s, which dominated passenger air transport in the 1960s and remained common through the 1970s. Boeing also offered a smaller, faster version of the aircraft that was marketed as the Boeing 720.
Although it was not the first commercial jet in service (that distinction belongs to the de Havilland Comet), the 707 was the first to be commercially successful, and is credited as ushering in the Jet Age.
The 707 and 720 (also the USAF variants, C-135 & KC-135 airplanes) were based on the aircraft known as the 367-80. The "Dash 80" took less than two years from project launch in 1952 to rollout on May 14th, 1954 for a cost of $16 million.
The original 367-80 prototype aka "Dash 80" inshrined at the Smithsonian Institute Air & Space Museum.
