SEATTLE--Sunday was a big day for Boeing. This morning, its all-new 747-8 Intercontinental took off on its first-ever test flight. The plane, which is said to be the fastest and most fuel- and cost-efficient passenger aircraft in Boeing's history, has a planned late 2011 first customer delivery.
Four-and-a-half hours after taking off from Paine Field in Everett, Wash., the plane touched down--seen here--at Boeing Field. During the flight, the pilots took the plane as high as 20,000 feet, and up to 250 knots, and put it through a series of tests.
