It was a variant for Qantas, thus had its The 707-120B had Pratt & Whitney JT3D-1 turbofan engines, which were quieter, more powerful, and more fuel-efficient, producing 17,000 lbf (75.6 kN) each, with the later JT3D-3 version giving 18,000 lbf (80 kN). A quadjet, the 707 has a swept wing with podded engines. Only a few aircraft were delivered as pure freighters. From 1965, -320Bs had the uprated -320C undercarriage allowing the same 335,000 lb (152,000 kg) MTOW. The smoke you see is the 1700 pounds of water injection used for the Boeing 707s JT engines in those early days. Pakistan Air Force Paraguay.

It was to be powered by four Pratt & Whitney JT3D-15 turbofan engines and would have had a 10-foot (3.0 m) extension in wingspan. The 505 model would have had a fuselage 45 feet (14 m) longer than the 707-320B and would have carried 209 passengers in mixed-class configuration and 260 passengers in all-economy configuration. The 707-320 Intercontinental is a stretched version of the turbojet-powered 707-120, initially powered by JT4A-3 or JT4A-5 turbojets producing 15,800 lbf (70.3 kN) each (most eventually got 17,500 lbf (77.8 kN) JT4A-11s). The 707 was designated the 720 when it was modified for short- to medium-range routes and for use on shorter runways. Quote: "The Boeing 707, the airliner which introduced jet travel on a large scale." Its type certificate was issued on June 30, 1960, and it entered service with Compared to the 707-120, it has a length reduced by 9 feet (2.7 m), a modified wing and a lightened airframe for a lower The 707-120 was the first production 707 variant, with a longer, wider fuselage, and greater wingspan than the Dash 80.

A total of 335 of this variant were built, including some with JT3D-7 engines (19,000 lbf (85 kN) takeoff thrust) and a takeoff weight of 335,000 lb (152,000 kg). History at your fingertips The addition of two additional emergency exits, one on either side aft of the wing raised the maximum passenger limit to 219.
Though initially fitted with turbojet engines, the dominant engine for the Boeing 707 family was the The final 707 variant was the 707-320C, (C for "Convertible"), which had a large fuselage door for cargo.

For example, In the 1980s, the USAF acquired around 250 used 707s to provide replacement turbofan engines for the The 707 is no longer operated by major airlines. (The 707 and US Air Force's KC-135 were developed in parallel from the Boeing 367–80 prototype.) In fact the J57 that powered the B 52 had similar water injected assistance.
At the time, nearly all of Boeing's revenue came from military contracts.
