Preparedness in emergency is important, including in a flight. It is necessary for passengers to know flight safety regulation. But, more importantly is to be familiar with the action in an emergency.
Passenger safety information briefing and briefing cards on the plane presented before flight is not enough, though. It is needed to be shown before it in the passenger waiting area. I imagine in this room we can try wearing life jackets for dramatic emergency landing, using exit emergency door, etc.
