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 untik the end, pass the 0:33 mark.
The impact was so hard that the fuselage was bent before the wings. You can clearly see the aluminium skin crumpled by that twist in these two videos.
I've never seen this happen. Unlike its successor, the fully composite-made 787 Dreamliner, the Boeing 767 uses aluminium alloys. It also uses Kevlar fairings and access panels, plus carbon fibre reinforced plastic composites on the wings.
The 767 is a very popular wide-body twin-engine aeroplane, still in production since 1979 in different variants. In fact, it became the most popular transatlantic plane in the '90s. [Thanks Jorge Mozo!]
