Boeing 707


For many airlines the 707 was the first jet airliner in service replacing older propliners. A total of 878 commercial 707s have been built but there was also a large number of aircraft produced for military use. Originally equipped with JT3B-engines some military variants have been re-engined with the more advanced CFM56.

For the modelplane fiberglass nacelles are available either for the JT3B or the wider CFM56 engine. The 707 has a large wing area giving the model a low wing loading. The outboard engines are far away from the fuselage so the pilot needs a lot of experience in case of engine failure.
