A few years ago, Boeing was struggling. Sales were slipping, financial forecasts grim. Meanwhile Airbus, a foreign competitor, passed the former champ in total sales. Now the tables are turned. There are several reasons for the stellar advance sales of Boeing's new 787 Dreamliner, but I can't help but point out one: After years of research into lightweight carbon-fiber, which now replaces heavier aluminum for the jet's fuselage and wings, the Dreamliner can sail with an estimated 20-30 percent less fuel per passenger. What's the company's reasoning behind increasing fuel efficiency? It's better for business, of course.
