The 787 Dreamliner is Boeing’s newest commercial aircraft offering unmatched fuel efficiency, resulting in exceptional environmental performance. The airplane will use 20 percent less fuel for comparable missions and travelling at speeds (Mach 0.85) similar to today’s fastest wide bodies.
The 787 is the first commercial airplane to make the change from metal to composite structure. The majority of the 787’s major structure is made out of composite material. The Dreamliner is the first commercial airplane to be built with a one-piece fuselage. Manufacturing a one-piece fuselage section eliminates 1,500 aluminum sheets and 40,000 to 50,000 fasteners.
