I'm only now seeing this post. First and foremost I'm inspired and humbled by your quick thinking and decisive approach to such a situation. Could I say I'd do the same? Maybe not since it's a scenario I've never had to misfortune of dealing with. I bloody well hope so though. I can't really offer up any more input than what has already been given by everyone else here. Out of interest have you done any other preparation with your family in case of future emergency and/or you not being there?
