Hopefully this ends the knee-jerk idiocy of a locked cabin door where no one can enter. So many scenarios where safety can require entry. How’d someone like to be on a flight with an incapacitated cockpit crew on the other side of the door where all you can do is watch out the window as the plane ends the flight in a spectacular and otherwise avoidable crash?
The crew inside the cockpit can override someone trying to get in the cockpit. They just showed it on CNN. The switch is usually on “Normal” meaning that the pilot can leave the cockpit and would be able to get back into the cockpit via the code keyed into the keypad, even if the other pilot was in distress. Anyone with the keycode could get it. If the switch is moved to “Lock” the pilot inside the cockpit has the ability to disable the keypad and lock the the other pilot out. It would have to be a deliberate act to do so.
Sounds like terrorism, not a medical situation.

If the locked door is keeping terrorists out, maybe their only option is inside the cockpit
