Video of B787 wing flex

I remember when the 777 tests were done. The wings were pulled 24 feet above its normal position before they broke during a full scale test. I believe it was half a million pounds of pressure on each wing, (that's equivalent to the weight of a fully loaded 777 on each wing!! ) until both wings broke at the predicted position. Also on the older 747, that was pulled to 28 ft of deflection before it broke after an expected 7ft deflection in heavy turbulence and a design break point of 21ft. So when it didn't break they just kept pulling till it gave in.
Super cool video of the trip7 wings busting, I can still vividly hear that loud noise!
NOTHING TO DO with spoiler deployment. The deployment is contemporaneous with the nose dropping, which drastically reduces the angle of attack on the outboard wing section. Note, too, that the spoilers aren't anywhere near the deflected (outboard) part of the wing.
I agree. The win is no longer producing lift, at least not to the extent it was before landing.
Nobody is claiming the wing flex is due to spoiler deployment.
You guys are both right,but that is coming from the first line of the story. The wing does flex back down but not because of spoiler deployment.
see video description under title
He's just saying that it's happening at the same time as spoiler deployment.
