Dani no it isn't. It's a double failure (the door and the incapacitation)
A double system failure is something I have experienced twice in my career (33 years airlines, 10 before that flying elsewhere in aviation) one of which caused a high speed rejected T/O when two utterly unrelated systems failed at precisely the same moment. No-one (including me) could believe it, but the evidence was there in front of our eyes.
As I said in my post, it's a long-shot, but the prevention is so simple and has no cost that I'll stick with it if I may. I don't have a choice anyway - it's SOP in my outfit!
