Posted by Courtney E. HowardEVERETT, Wash., 26 Sept. 2011. Officials from Boeing (NYSE:BA) and ANA have signed the formal documents that complete the contractual delivery of the first 787 Dreamliner, following a series of flights, inspections, and the transfer of funds. Celebrations marking the milestone begin today in Everett, Wa. A delivery ceremony, culminating with the customer flying its first Dreamliner home from Paine Field to Tokyo, Japan, is scheduled for Tuesday. Composite materials, more-electric systems, advanced aerodynamics, and modern engines are intended to make the 787 more fuel efficient and provide lower operating costs than other aircraft. Other innovations are designed to deliver cleaner cabin air, higher humidity, and lower cabin altitude. Larger windows with electrochromic shades, bigger onboard luggage bins, and LED lighting round out the all-new platform.
