 The 707-320 Intercontinental is a stretched version of the turbojet-powered 707-120, initially powered by JT4A-3 or JT4A-5 turbojets producing each (most eventually got JT4A-11s).The interior allowed up to 189 passengers, the same as the -120 and -220 series, but improved two-class capacity due to an 80-in fuselage stretch ahead of the wing (from to ), with extensions to the fin and horizontal stabilizer extending the aircraft's length further.The longer wing carried more fuel, increasing range by and allowing the aircraft to operate as true transoceanic aircraft.
