The first model in Boeing's new family of 737 twin-jets, the 737-700, obtained U.S. type certification in November 1997 and has since entered airline service. Two other models in the "Next Generation" family of airliners, the -600 and -800, are expected to enter service during 1998, while development of the 737-900 is now under way.
