The problem with this, of course, is that most of us don’t look very good in abbreviated swim-wear. And airports are often cold. I’m not anxious to see most flyers in a bikini.
The last time I flew, the TSA guy confiscated my breath mints (the little breath assure capsules with parsley oil in them). They were foil backed, and that set off the scanner… and I suppose they might have been explosive or something. Or maybe the TSA guy was just an idiot.
You decide.
