>>>The pilots are not going to leave the cockpit armed or unarmed.
That may be the way all the proposals (and eventual procedures) say it's supposed to work. Someday, should a perp in the back start killing pax and/or FAs off in an attempt to get up front, I think it's inevitable human nature that one of the flight deck crew is going to come out and attempt to stop the immediate carnage, despite whatever the manuals say about everyone aft of the cockpit door being "expendable" until the aircraft gets on the ground.
I know all they reasons they shouldn't come out, I just don't know how reasonable it is to expect someone's being able to ignore what's happening in the back.
I pray the you or any other crew is never in the situation...
