The Aircraft
The Boeing 737 was developed in the 1960s as a low-cost development of the 707 and 727. It’s the only Boeing “narrow body” airliner still in production. There are 9 versions, ranging from 85 to 215 passengers. While not approaching the Bf-109 in numbers, the 737 is the best-selling jet airliner in history, with 6638 delivered, with 2186 more on order as of December 31, 2010 (Editor: Boeing source).
The 737 in this kit is the -400 version, with CFM-56 engines. Because of the low wing and large diameter of the engines, the lower side of the nacelle is flattened, giving a distinctive “hamster pouch” look. The -300 and -500 versions differ from the -400 in fuselage length, with the -400 being 10 feet longer than the -300 and the -500 is 8 feet shorter than the -300.
