Yep, and apparently quite a bit. On my second-worst turbulence flight, I was seated by the FA jumpseat. They were, of course, belted in since the plane was bouncing like a bronco. This led to an interesting conversation about one of the FA's worst turbulence experience. He said that it was in Iceland, and he was utterly amazed to see just how much flex those wings have without snapping off. Compared to that, he swore that what we were experiencing was nothing. Turbulence doesn't freak me too much, but if it ever starts to I just remind myself of his story.
