Photo Gallery Dreamliner Launch
Boeing unveiled the Dreamliner at its Everett, Wash. assembly plant last July.
Made with next-generation materials like composite plastics and carbon fiber, the plane's wings will be put to the test in the months to come -- engineers think they might be flexible enough to touch wingtips above the fuselage.
Dreamliner customers will be able to choose between GE and Rolls Royce engines.
Suppliers, customers and employees were on hand to celebrate the launch.

You break it, you buy it: Each jet will cost more than $162 million (103 million).
With passenger flights set to triple by 2030, Boeing is betting on smaller, more flexible planes to serve demand for point-to-point flights.
The Dreamliner is being touted as a "green" competitor in the airline market, with increased efficiency and lower-altitude flights.
The Dreamliner is the first commercial airliner made mostly of carbon fiber. More than 70 percent of the plane's components will be manufactured outside the US.
