What I don't understand is why there would be a keypad to enter the cockpit if it can be overridden from within.I assume the override is there in case the pilot(s) can hear a commotion outside and might fear an FA being forced to use the keypad to gain entrance.I suspect that there has not been a single incident of an FA being forced to enter the keypad code.....so it would seem that this override presents more of a risk in having it available.It would be suicide for an FA to open the cockpit door under duress/threat and an air marshal would surely be able to prevent that............
9/11 also wouldn't have happened if the security services had acted on the information they had about the hijackers or if the people on the aircraft hadn't allowed the hijackers to take control. Pre 9/11 the assumption was that hijackers would land the aircraft and then negotiate the relase of it it and everyone aboard, therefore those aboard were advised not to resist. Post 9/11 the assumption is that hijackers will use the aircraft as a weapon and therefore those aboard will violently resist anything vaguely resembling a hijack attempt.
There are plenty of things which may help prevent a repeat of 9/11. Pretty much all of those things will have negative side effects. In the case of locked and armoured cockpit doors there is strong evidence that the side effects outweigh the positive effects.
