I went through an airport security screening point in civvies once.
Even though I showed complete disdain to the 'goons', raised an eyebrow when they asked me if I had undergone an explosive trace detection test before (having even put the latest copy of "Flying" magazine through the x-ray machine along with my car keys that had little metal airplanes attached to the key ring!), huffing and snorting every step of the way they didn't get who I was!? (By the way I would of worn my ASIC as I usually do yet alas it had been stolen from my car the night before!)
They only twigged when while confiscating my can of 'Impulse' (Tease), sans lid, one of them saw the collection of comfy ladies underwear in my man bag that they realized I was indeed an aviator.
