How did a wounded Captain Smit Machchhar open the FZ1073 cockpit door?
That is the design gap this incident exposes. The door can't tell a captain letting in help from a pilot letting in an attacker. If one pilot turns hostile, the other pilot is the only person on the flight deck who can open it. If he is hurt, the door stays shut until help arrives, whether or not that help is needed.
