Does it have a cotton crotch?

I finally got the opportunity to pass through an airport full body scanner while traveling out West. With my hands above my head, I tried to imagine my body images being scanned by a TSA agent in a remote location. At least that's what they tell you. Who's to say that a group of them aren't sitting on a couch, swigging beers and enjoying a virtual peep show? The actual scan took longer than I expected so I assumed that they were laughing about my steel reinforced under-wire bra that if I was hit full on by a truck, it would be the only thing still standing.

Could my scan ever end up on You Tube? Supposedly the setup has zero storage capability and once the officer has viewed the very graphic image and resolved "anomalies", it's erased from the screen permanently. I don't believe it for a second.

A professional screen printer, Steve Bradshaw, of Poynton, England, is marketing X-ray-proof underpants printed with barium sulfate, aluminum, ground glass and other supposedly X-ray scattering materials to stop what he considers "invasive breaches of privacy" at airport security checkpoints. Fleshy parts are protected but large metal objects (all you guys with BIG GUNS) would be revealed.

So do they come in boy shorts, hipster, bikini, thong or the big granny panty version?
