The first flight of Boeing's new 787 jetliner brought no surprises _ exactly what pilots, engineers and company officials had anxiously sought for the long-delayed aircraft.

"The airplane responded just as we expected," Randy Neville, one of the two pilots, said after touchdown Tuesday at Seattle's Boeing Field. "It was a joy to fly."

Boeing has billions of dollars and its reputation riding on the sleek, blue-and-white aircraft that lifted off from Everett's Paine Field on a flight over western Washington, beginning the extensive flight testing program needed to obtain Federal Aviation Administration certification.

The widebody jet, the first commercial airplane made mostly of lightweight composite materials, is more than two years behind schedule because of parts problems and labor trouble. Chicago-based Boeing was determined the plane would fly before the end of the year to prove the program was back on track.

Neville and chief pilot Mike Carricker performed a variety of basic system checks, including testing the landing gear and the flaps, before landing about three hours later. Deteriorating but typical Northwest winter weather _ rain, cold and wind _ brought the plane back about an hour earlier than planned.

Before takeoff, the 186-foot-long aircraft paused for several minutes at the end of the runway for final checks, adding to the tension for Boeing employees, customers and airline executives standing on the tarmac. Loud cheers and applause built as the plane started its takeoff roll and took to the sky, its two huge engines kicking up clouds of mist.

"It's very historical. I can't think of a thing about it that I'm not impressed with," said Joe Bierce, a flight instructor for Delta Connection in Jacksonville, Fla., who was among the 25,000 people who gathered to watch the takeoff.

The 787 is a radical departure in aircraft design. Where other passenger jets are made mostly from aluminum and titanium, nearly all of the 787's fuselage and wings are made of lightweight composite materials such as carbon fiber, accounting for about 50 percent of the aircraft by weight.

Those materials have long been used on individual parts such as rudders, and on military planes, but the 787 is the most ambitious use of the technology aboard a passenger plane.

Boeing says the aircraft will be quieter, produce lower emissions and use 20 percent less fuel than comparable planes, while giving passengers a more comfortable cabin with better air quality and larger windows.

Officials cut the flight a little short after rain reduced visibility at Boeing Field and the aircraft ran into poor weather off the Washington coast.
