This is bad ass. 777 wing test. https://www.youtube.com/watch?v=rak2HldVp9M https://www.youtube.com/watch?v=rak2HldVp9M That amount of deflection is insane, you'd never see that in normal flight. (Pilot here.) The article mentions “turbulence penetration speed” or Vb and "maneuvering speed" or Va. Simplistically these are speeds below which the wing will stall before it breaks. The wing is designed to gradually stall in these conditions not abruptly. You really won't feel it unless you know what you're looking for and you're reasonably experienced as a pilot. The wing just kinda gradually craps out rather than being over stressed, and just as quickly starts to fly normally again. Seriously the plane can structurally take extreme turbulence when flown at or below the proper safety speed, even though by definition at extreme turbulence the pilot is just along for the ride (the plane is not considered controllable with extreme turbulence, you get to pick a speed and kinda sorta a general direction, you don't get to control the altitude or the attitude). I've not experienced extreme turbulence and have no desire to, but have been in severe turbulence and don't need to do that again. But the plane is alright.
