Boeing pulls the sheet off its biggest airliner ever this weekend, the 747-8 Intercontinental. It is an extreme makeover of the plane that ushered in the jumbo jet era, but despite its impressive tech and imposing size it won’t be a big seller. Still, it offers further evidence that Boeing has found a winning strategy in its race against Airbus to make commercial aviation cleaner and greener.
...The 747-8 is an impressive aircraft. It is just over 250 feet long, making it 18.3 feet longer than the current model and the world’s longest aircraft. It will carry as many as 467 people in a three-class configuration.
The technology being put into the 747-8 is no less impressive. In addition to efficient new engines and all-new electronics and flight control systems, the airplane has an all-new wing that will dramatically improve the efficiency of the airplane over the older 747s. Boeing claims the 747-8 will be 30 percent quieter and 16 percent more fuel efficient than its current version, and it will offer 13 percent lower seat-mile costs...
