I spent a bit of time looking around the internal web for info and couldn't find anything. I recall that the 777 wing failure test bent the wings up something like 17 feet before they broke (this *after* the full life cycle fatigue test). But that's just my memory and that's been known to fail before! Sorry I don't have a real answer for you.
