VS also have re-inforced cockpit doors (first airline in world to do it after 11/09)...and just today have announced that they will be installing cctv camera's outside the flight deck on every a/c by spring 2003. The A346 will already have them when they are delivered, and the rest of the fleet will get them soon.
Thing is tho, how will the flight crew react to seeing live pictures of some stewardess or child being held hostage outside the door, would they then keep the door closed ?? - I think they may be better off not seeing that (if it were ever to happen), less chance of them opening the door then, if they can't actually see that going on outside....
But on the other hand, it would give them some advanced warning to have that fire-axe ready, should anyone try to get in.
Also - what good is just making the door bomb/bullet/axe proof - wouldn't they just take out the walls around it that aren't protected instead ?
I think having something like a pepper spray would be safer, and would still disable an intruder long enough for help to intervene (what did Mr. Myagi say in Karate Kid ? - "Man can't see - can't fight !
), and would not need to be kept under lock and key like any sort of gun/stun gun, so would be more at hand should anyone manage to get in, plus then the intruder would still be alive to face the consequenses provided the pax didn't beat them to death !!.
