The Boeing 787 took to the skies for the first time this morning over Western Washington. Its three hour test flight started in Everett, headed out briefly towards the Pacific Ocean and ended in Seattle. The 787 is the first commercial jetliner to be made out of mostly lightweight composite material, which allows the plane to consume less fuel while providing a more comfortable cabin interior. Some 850 have already been ordered by more than 50 airlines. The sticker price is approximately $175 million US each. Passenger flights should begin by the end of 2010.
