787 Dreamliner completes wing-bending test
If you've ever felt a little queasy watching your plane's wings flex under the strain of being at 10,000 feet, rest assured that they can bend a lot further. Just how much pressure modern airliner wings can take is demonstrated by the latest 787 Dreamliner news from Boeing. During a recent "ultimate-load wing up-bending test," the 787 was subjected to loads 150 percent greater than it can expect to endure during service with the wings flexed upward by approximately 25 feet (7.6 meters) over a period of two hours.
Boeing is positive about the initial results of the test although more extensive analysis is required over coming weeks.
"We are looking forward to the technical team's report on the details of the test results," said Scott Fancher, vice president and general manager of the 787 program.
"The test program has been more robust than any conducted on a Boeing commercial jetliner," said Fancher. "It has taken countless hours of hard work by the Boeing team and our partners to work through the static test program."

I\'d like to see them let the wings go and watch them snap back...
Or to do the same test downwards....
Even better - to run one wing UP and the other wing DOWN - at the same time..
And then let them snap back.... Wooooooo it\'s explodes just like a balsa one!
Boeing has long designed their planes to withstand anything a pilot can do, short of deliberately crashing.
Google for Boeing barrel roll. Test pilot Tex Johnston flew a prototype 707 through a barrel roll, just to prove it could do it. I\'d like to see Airbus try that with any of their airliners!
The Federal department of Transportation was testing Composite Pilings for over passes and they FAILED! And they weren\'t at 50,000 feet! Now you figure it out!
Being a retired Safety Director, to me Boeing is \"ROLLING DICE\"
I remember when the British Comets went apart in Midair, due to structure failure, due to the shape of the windows, they exploded in mid Air, 5 of them, till they found out the cause. The Comet was the first Jet Air liner.
The 787 is a move in the right direction and you can be sure it will be safe. To certify such an new Airliner is not something that is taken lightly.
