    I was watching that video earlier at work. That must've been an earth-shattering BOOM when the thing finally gave way.

    Heh. I don't know how I'd feel about riding in a 787 with plastic wings. I'm sure it'd be fine, but just the thought is worrying.

    Then again, I don't fly, so hey, go for it Boeing!

    That was a 777, which I think has a composite skin but an internal aluminum frame.

    Yeah, the video was of a 777. I saw the link to the video in a discussion about the carbon-fiber winged 787 on Slashdot, though.

    I can't imagine it's remotely possible for that much force to be exerted on the wing during anything resembling normal flight, so it's probably more of a "let's see what happens, just for the hell of it" kind of test, but boy, it sure didn't fail gracefully, did it?

    If the plane were to make a really high G turn, that'll do it..

    An airliner, though? And that much in excess of rated capacity?

    This kind of loading is only expected in absolutely, ridiculous, oh-my-gosh-we're-all-gonna-die types of turbulence...and then they went 54% beyond that. Theoretically the wing will stall before reaching that load.

    If seeing a wing deflect 24 feet before breaking doesn't give you at least some confidence, you might not be cut out for stepping outside your house.

    The 787 wings will be much more flexible (and theoretically able to take a higher load). There's been some speculation that if Boeing tries to load them all the way to failure, they'll have bent so far the tips will be touch together above the fuselage.

    The 777 is aluminum framed and skinned, but it does use composites in the tail, passenger cabin floor beams, and some of the fairings. According to Boeing, about ~9% of the structural weight is composite. Compare that to the 787 where over 50% of it will be composites. Most of the fuselage, as well as the wing box and most of the wing skin is carbon fiber. Boeing has actually bought out most of the world's carbon fiber production for the next five or so years it will take producers to up their capacity.

    Among the many neat things about the way Boeing is doing this is it actually lowers the production cost despite a more expensive material. They've built huge mandrels that go on essentially a giant lathe used to wrap the carbon fiber around in a complete barrel section. Then they stuff the big parts inside and basically glue/rivet the barrels together. For other planes they have to arrange the frames on the assembly floor and spend days riveting aluminum panels onto them, then squeeze everything in through the doors. The reduced number of joints also means fewer places for cracks to form, and there's less worry about corrosion (yes, aluminum corrodes).

    Quite probably every new airliner for the next 20+ years will be built this way.

    They're testing it to 50% more than what they "think" is the max the plane will encounter. I'm sure I can cook up a scenario that well surpasses that. Hurricane....

    Just taxi it down your normal ride route to work. That should do it.

    This isn't Hollywood, pilots usually avoid hurricanes.

    Yeah I doubt the 787 can stay upright on wet metal.
