Out of all the survivable emergency events, surely depressurisation is the most common?
I mean, landing on water....and surviving...how many times has it happened? Single figures?
then there is the emergency landing with slides....happens occasionally.
I would imagine the depressurisation events are far commoner and almost 100% survivable.
So I would say it would pay to give a bit more emphasis to this and explain in the safety briefing exactly what will happen.
