Background: The first 737 entered service in 1968. Since then, it has become the most prolific airliner in the world. Over 4,000 have been built and another 900+ are on backorder. Sales of the latest generation of 737 continue. The military of several countries use the 737 for VIP transport and other duties.

There are three basic designs and several variations of each design in the 737 family for a total of 14 deferent fuselage/wing combinations that have been produced by Boeing. This does not include modifications of the airframe for military purposes. The one common denominator among the designs and variations of the 737 is the fuselage, which itself varies in length. The main external deference between the three basic designs, is that each has a unique wing/engine configuration.
