I made the point about runway overuns because I remember reading the report into the crash of the Air France A340 and noting this bit:
Extract from the report:
The two crew members who had suffered serious impact injuries were able to perform their emergency duties effectively. Passengers who incurred impact injuries were ambulatory during the evacuation. One of the cabin crew, seated in the same general area as the crew and passengers who incurred serious impact injuries, was not injured. This cabin crew's seat was aft-facing; the other seats were forward-facing.
So maybe there's something in it...
