Aeroflot Flight 593 - Wikipedia, the free encyclopedia
Now I am not saying this kind of thing is likely but it gives an indication of what can go wrong while someone is "having a go". I know it was a complex aircraft and not representative, just making a point.
I agree with hands_on123, if it feels like the "board of enquiry" would disapprove of your actions, then that gives you a test of reasonableness, but doesn't help with the legalities.
