I'm trying to distinguish between things going 'wrong' and things turning 'lethal' here - the latter of which should only happen if something is wrong with the machine or the passengers, just to touch the tip of the iceberg. Human error leading to such a situation is so easily avoided with a good plan of action on terra firma before taking an aircraft away from the ground.
And yes, the idea you quoted me on is questionable, I agree.
Cheers and thanks for the input, Jack.
