I know this doesn;t help you diddly squat, but after reading some of the others I thought i'd add my beauty.
In my military days I was to travel north from BNE on a commercial flight before departing the country on a service flight. I was told to check my weapons in with my bags, but keep the firing pin and trigger mechanism on me. No one said a thing to me passing through security. To me all this seemed fine but when i got chatting to an officer I was travelling with on the flight it appeared he did things in reverse. So essentially on board within arms reach we could have had a complete assault rifle and pistol.
BUt on my return to oz we thankfully didnt have to deal with our weapons on board with us although I had the spoon that i had used for every meal for 6 months confiscated.
