"Bad landing" does not equal "crash". Impending doom is different than a "bad landing".
Now I can always structure posts like we're reading a manual, to attempt to cover every possible angle, but I tend to trust that people can make reasonable inferences on some things. Obviously it's hard to cover every possible angle. Though based on the remainder of my earlier post (like the part about safe vs unsafe, my qualifier of "don't particularly care about", and I do care about porpoising, it would be rather unreasonable to think otherwise) you could reasonably infer that while I might let someone drive it into the pavement or get lost in a crosswind, I generally won't let them trash the machine.

Not on anything I fly. If that was a limitation I'd know about it and behave accordingly. Also sounds like an Airbus thing.
