I took my roommate to the airport a few months back. When she got back, she told me a horror story about getting pulled out of the line, thoroughly searched, scanned and questioned for an hour. They eventually cleared her and said the scanners had detected an unknown residue on her luggage that could be bomb making materials. She had no idea how.
Of course, I took her in my SUV I use for racing and her bags were in the back. I'm sure there was all kinds of fuel residue back there. But it was also winter, electric season so my bet is on the Paragon fumes
