The one that says to storm the cockpit on final approach, evidentially. Seems to me that if a flight crew member is going to open the cockpit door for whatever reason, instead of locking up the gun the remaining crew member should be holding it pointed at the door.
This is the same idiocy that launched TSA in all its glory.
With reinforced doors, the only time a pilot would need a firearm is when the cockpit door is open... Yet that is the only time he cannot have a firearm.
Brilliant plan, TSA.
There is an easy way to spot pilots who are part of the weapons program. I won’t say, but it is pretty obvious and could make pilots targets inside airports.
