Although it was not the first jetliner in service , the 707 was the first to be commercially successful . Dominating passenger air transport in the 1960s and remaining common through the 1970s , the 707 is generally credited with ushering in the Jet Age . It established Boeing as one of the largest manufacturers of passenger aircraft , and led to the later series of airliners with `` 7x7 '' designations . The later 720 , 727 , 737 , and 757 share elements of the 707 's fuselage design .   The 707 was developed from the Boeing 367-80 , a prototype jet first flown in 1954 . A larger fuselage cross-section and other modifications resulted in the initial-production 707-120 , powered by Pratt & Whitney JT3C turbojet engines , which first flew on December 20 , 1957 . Pan American World Airways began regular 707 service on October 26 , 1958 . Later derivatives included the shortened long-range 707-138 and the stretched 707-320 , both of which entered service in 1959 . A smaller short-range variant , the 720 , was introduced in 1960 . The 707-420 , a version of the stretched 707 with Rolls-Royce Conway turbofans , debuted in 1960 , while Pratt & Whitney JT3D turbofans debuted on the 707-120B and 707-320B models in 1961 and 1962 , respectively .   The 707 has been used on domestic , transcontinental , and transatlantic flights , and for cargo and military applications . A convertible passenger-freighter model , the 707-320C , entered service in 1963 , and passenger 707s have been modified to freighter configurations . Military derivatives include the E-3 Sentry airborne reconnaissance aircraft and the C-137 Stratoliner VIP transports . Boeing produced and delivered 1,011 airliners including the smaller 720 series ; over 800 military versions were also produced . Ten Boeing 707s were in commercial service in July 2013 .
