How would something like that stop another Bojinka plot?

In case you didn't notice, IT FAILED!!!

Didn't Bojinka fail because some twit had a fire in his apartment? I don't see how "impenetrable doors on cockpits" would have stopped such a plot, though I can see how incresed airport security would.

All that was necessary was to put impenetrable doors on cockpits.

I'm not even sure that would stop the next Richard Reid. Reids mistake was to light his shoe in front of passengers. Had he walked to the bathroom and lighted them there in privacy, it would have been a different story.
