The 707-120 and 320 were later reengined with JT3D turbofans (in place of the original JT3 and JT4 turbojets) to become the 707-120B, and the 707-320B respectively. The 707-320C was a convertible model, the 707-420 was powered by RollsRoyce Conways, while the proposed CFM-56 powered 707-700 upgrade was flight tested in the late 1970s but never ...

Compared with the 707-120 the 720 also had reduced fuel capacity and a lower max takeoff weight. But many components were interchangeable between the 720 and 707, while inside the cabin the 720 and 707 shared the same passenger interior and flightdeck. The initial 720 (bound for launch customer United) first flew on November 23 1959.

2006年7月13日 · Early model 707's were indeed equipped with (straight-pipe) turbojet engines, and some models used de-mineralized water injection during takeoff to increase thrust. When the JT4A turbojet engine was available, these were fitted to -300 long body models, and these engines, having more thrust available, did not need water injection.

2024年10月9日 · For example, I assumed there was a reasonable fleet commonality between Boeing jetliners from the 707-120 to the 737-200. What of other Boeing aircraft from the 747-200 to the 777-200? I'm assuming those possess significant fleet commonality among themselves but not with the earlier aircraft types. True/False?

2007年11月15日 · The empty weight of a 707-120 is about 120,000lb., and about 150,000lb. for a -320. The max takeoff weight of a -120 is a little under 260,000lb. (fairly similar to a higher MTOW 757-200), making it a heavy. The -320's MTOW is about 334,000lb. I don't know about the …

2018年10月18日 · A very rare plane. Only 5 707-220 were built, of which one crashed before delivery to Braniff. This -220 series combined the shorter fuselage of the 707-120 with the more powerful P&W JT4A turbojet engines of the longer 707-320. It was the hot-rod of its day.

2015年12月4日 · As already mentioned, the 707-120 was designed largely for U.S. transcontinental routes and was of little interest to foreign carriers who preferred to wait for the long range 707-320/420. Quoting doulasc ( Thread starter ): Pan Am's first jet flight was a Boeing 707-121 non fan from New York to Paris in 1958 and had to make a fuel stop in ...

2006年6月28日 · I never saw a 707 use containers, so I learned something new today. It does look similar to the narrowbody Airbus containers... Some DC-8's, at least some UA ones, had a containerized lower lobe cargo system. But the containers were round-bottomed, and not anything standard to any other aircraft. They had special dollies the containers fit into.
