The Boeing 787 Dreamliner is a mid-sized, wide-body, twin-engine jet airliner currently under development by Boeing Commercial Airplanes. It will carry between 210 and 330 passengers depending on variant and seating configuration. Boeing stated that it will be more fuel-efficient than earlier Boeing airliners and will be the first major airliner to use composite materials for most of its construction. Boeing's development of the 787 is also innovative in the collaborative management approach with suppliers.
On January 28, 2005, the aircraft's development designation 7E7 was changed to the 787. Early released concept images depicted a radical design with highly curved surfaces. On April 26, 2005, a year after the launch of the program, the final look of the external 787 design was frozen, with a less rakish nose and a more conventional tail.
Boeing featured its first 787 in a rollout ceremony on July 8, 2007, at its Everett assembly factory, by which time it had become the fastest-selling wide body airliner in history with nearly 600 orders. A total of 861 787s have been ordered by 56 customers as of April 2009. Originally scheduled to enter service in May 2008, production has been delayed and it is currently scheduled to enter into service in Q1 2010.
