When I was stationed at Elmendorf AFB many long years ago, a DoD chartered R&R airliner failed to make if off the runway--brakes had frozen, apparently, and because of the icy runway, the crew were flummoxed by the slow increase in speed and didn't react to it until it was too slow to fly and too late to stop. I don't recall that there were any serious injuries, but our office was one of many tasked with helping the passengers. (Incidentally, I thought that was silly, that the base JAG office was involved at all, but orders is orders).
So I was interviewing a retired MSgt, and he said that the toughest part of evacuating was getting past the idjets who were trying to get their carry-ons out of the overhead bins! With smoke filling the cabin, he found himself barking orders to leave things behind, but even that didn't work very well, since many of the passengers were military dependents and not active duty military. Luckily, whatever was causing the smoke didn't erupt into a major fire.
Basic rule: anyTHING can be replaced; your life can't.
