I saw the new bulletproof doors on the Virgin fleet. Nice new kevlar skins but looked like the same 60-80lbs pressure yeild plastic frangible door lock "snib" sticking out of the door.
BANG! Bullet fails to pass through the door but snaps the girlie-ass door lock off.
Take a look at the 767 door latch system next time you climb in. On "one" airframe I have seen I thought I might even have been able to get past the lock without a key. As for the inwards pressure, I doubt that the aluminum angle fillet (designed to stop the door slamming and passing all the way forwards into the flightdeck?) could offer much resistance against a hard shove.
Lucky these afghans are skinny little Fu.....
