Goodness.

If you happen to spy that sight whilst looking out your passenger window, it would be best to put down the SkyMall magazine, and pickup a Rosary - you're gonna need it.

EVERETT, Wash., March 28, 2010 – During ultimate-load testing at Boeing’s Everett, Wash., facility, the wings of the 787 Dreamliner were flexed upward by approximately 25 feet (7.6 meters). Engineers are reviewing the detailed test results and report that initial results are promising. The test exposed the airframe to the equivalent of 150 percent of the heaviest load it is ever expected to see while in service.

Almost forgot about this Dreamliner. When was it originally due for flight? A long time ago it seems. And what ever happend to the Euro EADS monster competitor? The whole field of commercial flight seems to have gone dark.

Another P I page says . . . FlightBlogger's source reported "no funny noises" in the test, according to a Twitter post.

Though they've still got to go through the data...but that's great news for the 787 program.

BTW..the 777 wing test

The wings flex quite a bit during normal flight, too.

I don’t understand.

Your post makes no sense without context.

"Your post makes no sense without context."

Look at the wings on that aircraft. This is the final "flight" test of the aircraft. Can you imagine seeing the wings on your aircraft do that while traveling in it?

If you do, your plan has some problems.

anyone who hasn’t seen the 707 barrel roll video on youtube, it’s definitely worth a gander.

I went through grade school with the twin children of a senior VP of one of the big airlines. He had flown in WW2 and was involved in the acceptance trials for the L1011 jumbo jet. He was at the controls and asked if it could do a barrel role and then proceeded to do one. Crazy man, but they bought a bunch of the planes, so all was forgiven.

The pilot and pax may have some problems, but the plane should be okay to get you to the nearest airport for maintenance, as the test has just proven.

If I saw that out my window I’d just be amazed I’m still in the air.

When they bent the wings on the Triple-7, they bent them until they broke. The article didn’t mention if they did that with the Dreamliner.

I was on my way home from Seattle on Friday afternoon. You can see Boeing Field from I-5, and one of the Dreamliners was there, getting ready to taxi. It was next to the new 747-8 Freighter, which is one big mother-hummin’ plane.

The airbus people can’t say that about the a380.

Which needs to be seen in context: The aerospace industry works with a safety factor of 1.5, meaning everything must be able to withstand 1 1/2 times the maximum forces that the aircraft will ever encounter. The Airbus wing snapped at 145% instead of 150%, some minor design changes / reinforcements put it over the 150% mark. Not a perfect showing, but still ok. You have to realize that more in this case isn't necessarily better, because if you reach 190% that means your plane is way to heavy and inefficient. So engineers try to hit 151% and sometimes they miss slightly.

>>>...anyone who hasn’t seen the 707 barrel roll video on youtube,<<<

I arrived in Seattle a few days after the infamous barrel-roll at he Seafair hydro races on Lake Washington.

That was all anyone could talk about at the time. Tex Johnson, the test pilot, was fired and re-hired all in one day after dozens of airline companys placed orders.

Some days it still seems that it's all Seattle has to be proud of and talk about - what with all the liberals here, it's a dull town

Never seen a jumbo jet wing bend that far. Is this craft’s wing designed to be less rigid, more flexible, than its predecessors?
