Genghis,
Should have also stated that we do the anthropomorphic dummy on all our escape hatches (except the explosive ones). Agencies also do the escape drills falling out onto mattresses before they join us on Cert flights.
I once did a cabin layout spiel on a Challenger to some Flight Checkers from Scott AFB. When we got to the Aft baggage bay, which is accessible in flight, they took one look at the door and rejoiced at the prospect of an escape hatch! Guess your view changes when somebody's shooting at you.
