The Boeing 787 Dreamliner is a mid-sized wide body, twin engined passenger airliner currently under development by Boeing's Commercial Airplanes Unit and scheduled to enter service in May 2008. It will carry between 210 and 330 passengers depending on the seating configuration, and will be more fuel effcient than comparable earlier airliners. It will also be the first major airliner to use composite material for most of its construction.
