The KC135 and 707 airliner were both developed from the Boeing 367-80 prototype of 1954. It was a huge gamble for Boeing that continues to pay off for the company. Over eight hundred KC135s were produced between 1956 and 1966, most of which are still in service. Over a thousand 707s were built between 1958 and 1979.
