Landing in a crosswind can be terrifying, but just watch this video and see how much the wings of a Boeing 767 flex during severe turbulence. It's... disconcerting.
Watch this landing of a Boeing 767 from All Nippon Airways. It's pretty rough, with the nose gear violently bouncing off the runway. Still, nothing too spectacular... until you see the consequences. Keep watching till the end, past the 0:33 mark.
