A thought on seeing the pictures with survivors.
Just looking at it from a survival-technical viewpoint: I think this summers' flip-flop slipper fashion was an unfortunate one. I would not like to have walked through the crash rubble barefoot.
Me neither, but I don't think most people get on a plane thinking what they should be wearing in case it crashes. If they did, they'd be wearing fire-retardant suits, crash helmets and an oxygen supply.
