With regards to the argument of 'why do you need a gun if you're behind an armoured door?', what people fail to realise is that the cockpit door is no undefeatable barrier.
Do you seriously expect the pax (sorry SLF !) to allow a sustained attack on the cockpit door after 9/11 ?
Those who think guns are needed on the flight deck have some crazy 'Wild West' mentality.
