Thing is, that 9/11 event 21 years ago is unlikely to be repeated. Not because some terrorists wouldn't try, but because it's highly unlikely to be successful now the people know about the game plan.
Pre 9/11, the thinking was the very worst thing that could happen in a hijacking was for the aircraft to crash. Now we know better.
A future attempt at a 9/11 hijacking is likely to see the terrorists overwhelmed by the rest of the passengers/crew - worst case it turns into another Shanksville. No one is going to obtain flightdeck access by holding a knife at a flight attendant's throat, because the crew on the other side of the door now know something far worse could occur if they open the door.
