I wonder what the absolute minimum "bang seat drill" would be that's considered acceptable ?
One of my favourite comments was from a T4 front seater who advised his passenger that in the event of an emergency he would loudly announce "EJECT, EJECT, EJECT" whereupon the passenger was to pull "this handle", and if he failed to do so the second message would be the words "Follow Me" written on the bottom of his boots.
