I think that reinforcing the cockpit doors is a great idea however, one little question pops into my mind. What do we do when/if this happens: You are in your seat and you hear one of the cabin attendants call out,"he's got a knife to my throat and he will use it if you don't open the door!!!" You might know this attendant fairly well, she might even be your wife/girlfriend. The scenario is not pleasant, but in light of sep. 11 nothing seems too far fetched.
