A Boeing employee works on the first Boeing Business Jet as it makes its way through the Boeing factory in Renton, Wash. The BBJ is a derivative of the Next-Generation 737, combining the 737-700 fuselage with the strengthened wings and landing gear of the larger and heavier 737-800. This combination gives the BBJ a range of 7,140 statute miles (6,200 nautical miles, 11,480 kilometers) and nearly three times the internal volume of the newest long-range corporate jets.
