With regard to the passengers carrying luggage off the aircraft, we see this every time there is a crash - when was the last time it has adversely affected the outcome? Of course, it does slow things down, and it does make it more likely, but when has it actually happened?
Passengers around the world will be seeing pictures of yet another 'plane crash' with a successful evacuation, and passengers taking their belongings with them.
Probably far more relevant, is that from the passenger figures published, the plane was only half full.
