Thridle Op Des - Not sure what your point was. Psychic ability? I wish. The point was to demonstrate that aircraft have had and always will have design problems. Manufacturers making claims about how safe their aircraft are should keep Murphy's Law and the Titanic in mind at all times.
As far as demonstrating that pilots can overstress their aircraft; sure we can. Hopefully wings and tails and such will stay attached. You should have seen the rotor blades on a 76 that had its RPM drop to around 46% when a pilot - to be charitable - screwed up an autorotation. Dampers ripped from blade roots and bent blades, and after recovery to 100% she still flew. Probably not a situation the engineers and test pilots envisioned.
Like I said above, checklist, common sense, and I might add a little prayer that everything works like its suppose to.
