Boeing's 787 Dreamliner flying a test flight. The airplane--which is expected to be delivered commercially in 2011--is made from 50 percent composites, 20 percent aluminum, 15 percent titanium, 10 percent steel, and 5 percent other materials. It is expected to offer airlines up to a 20 percent reduction in fuel burn thanks to the composite materials.
