I've had some folks allow as how maybe stripping to minimal clothing -- underwear, or in the case of women, a bikini, while standing in the line to pass through the airport scanners might be a way to bypass the pat-down, in lieu of the scanners.
I must admit that the idea of a line full of Playboy bunnies in micro-bikinis might enliven the wait; however, given what most people in the U.S. look like these days, that notion is not one to inspire lust. Use your imagination.
As I understand it, it's an either/or choice where they have these machines, no matter how brief your outfit. They will have to feel around your private parts, because of the underwear bomber. The only way to avoid this would be to be completely nude -- and you can book it, sooner or later some loon is gonna get caught trying to smuggle something onboard a plane up his Hershey Highway -- and that is gonna open another whole avenue of exploration.
When the guy lubes up the finger of his rubber glove? That's the day I stop flying anywhere. I already avoid it as much as possible -- the days when air travel was a fun adventure are long gone. It is getting to the point where it's gonna start costing the airlines money, and if it gets expensive enough, I expect that the bottom line is going to come into play.
