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.
