Boeing's 787 is a radical departure in design: By weight, about 50 percent of the plane is made of composite materials, instead of metal. The plane will be quieter, produce fewer emissions, and use less fuel than comparable aircraft. Passengers will travel in a more comfortable cabin with better air quality and larger windows.

Boeing's long-delayed dream takes wing: Two years overdue, the first 787 Dreamliner lifts off for a test flight in Everett, Wash. Boeing already has orders for 840 of the aircraft. The 787-9 Dreamliner is unique in terms of range, length, weight and cargo volume:


range, in nautical miles, the longest of the 787s


length in feet


maximum takeoff weight in pounds


total cargo volume in cubic feet
