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.
