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

Looks like I could override that with just a rubber band.

It's interesting that the LOCK mode only stays on for five minutes. Then the door either reverts to NORMAL mode (and the emergency access is allowed) or someone inside the cockpit must reissue the lock request. Note that the switch is momentary, and it cannot be left in OPEN or LOCK positions. Even if an incapacitated pilot accidentally touched the switch and locked the door, that would have only kept the door locked for five minutes. Don't know what happens if someone leans on the switch (with the rubber band, for example.) A good design would only register the edge of the signal, but not the level.
