The Boeing 787 Dreamliner is a mid-sized, wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes.
It seats 210 to 330 passengers, depending on variant. Boeing states that it is the company's most fuel-efficient airliner and the world's first major airliner to use composite materials for most of its construction. Its development has involved a large-scale collaboration with numerous suppliers.
On January 28, 2005, the aircraft's initial designation 7E7 was changed to 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 and more conventional external 787 design was set.
Boeing featured its first 787 in a roll-out 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. By December 2009, 851 Boeing 787s had been ordered by 56 customers.
The aircraft was originally scheduled to enter service in May 2008, but production had been delayed multiple times, and in August 2009, the scheduled service entry date was pushed back to the fourth quarter of 2010. The aircraft's maiden flight, originally planned for August 2007, took place on December 15, 2009 in the Seattle area.
