Who cares if it has or hasn't happened? The fact that it can happen and there's something you can do about it makes you grossly negligent if you don't.When has this _ever_ happened? Is it unsafe to do a cave dive without a jack to lift up the cave if it collapses on you? If you have a failure like this at max penetration you either have been grossly negligent in your maintenance or you got caught stealing from the collection plate and the man upstairs has it out for you.
