Rumet,
The door worked, the people failed because they opened the door. Never again will that happen because everyone has seen the result.
I hate to say it, but to a large degree, those in the back are now on their own. No amount of screaming or gore is going to ever get me to open the door again.
It takes a while to kill dozens of people with a knife. However, if you kill the pilots you can do it in a second with the controlls of the aircraft which has been demonstrated.
I am sure that from now on when ever a pax see someone trying to break into the cockpit, they are gonna get involved. Hopefully just like on the Southwest flight where they killed the person.
