Armed Flight Deck
Looks like the anti gun wusses have started to hijack this serious thread to tell the guys who are in the front line how it should be done. Like I said before - these people full of hypothetical reasons for not arming the flight deck will be watching the tragedy unfold on CNN.
When the suicide hijackers fly into the nuclear plant/battle group carrier/major building or what have you they (the unarmed flight deck push) will disappear into the woodwork from whence they came.
And for the airline beancounters - let me clue you in - the pax aren't coming back until they know the flight deck is secure.
