Boeing 707-320 Intercontinental

Boeing · United States · first flew 1958 · airliner

The 707-320 Intercontinental was Boeing's stretched, long-range variant capable of non-stop transatlantic service, and the definitive production standard of the 707 family.

Recognition (WEFT)

W — Wings	Low-mounted, swept
E — Engines	4 × turbojet, wing-mounted
F — Fuselage	Longer fuselage than -120 at 46.6 m — the full-length intercontinental body
T — Tail	Conventional

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Longer fuselage than -120 at 46.6 m — the full-length intercontinental body
Wider-span wing at 44.4 m with leading-edge slots for transatlantic range
Four individually podded JT4A or JT3D engines; ventral fin common on early aircraft

Longer and wider-spanning than the -120 domestic version; distinguished from the shorter -120 by its full 46.6 m fuselage and the wider wing panel visible when parked alongside.

History

Pan Am introduced it on the New York–London route in 1958, cementing the 707 as the flagship of the jet age. The -320C added a cargo door and convertible interior, making it the most-built sub-variant. Re-engined -320Bs with JT3D turbofans became the standard by the mid-1960s.

Variants

The -320B introduced JT3D turbofans and extended leading-edge devices; the -320C added a large forward cargo door for quick passenger-freighter conversion.

Where you'll see it

The backbone of global long-haul fleets through the 1970s; still operated by a handful of African and Middle Eastern operators into the 2010s.
