I wonder if the same orchestrated and efficient evacuation would take place, say on an Emirates A380 when a women tries to get off in front of a man or an infidel tries to get off in front of a non infidel.
I remember a Saudi airliner landing safely after an emergency, only to see all passengers die in the ensuing fire as they fought each other to get off the plane.
You are mistaken - That's the way they depart the plane
every time.
No emergency needed.
