The last time I flew out of Boston Logan (April 2012), there was a small sign (which I almost didn't read) warning that the X-ray scanners at *this* checkpoint (sadly, I can't remember which terminal) *were* powerful enough to fog film, and that NO film should be sent through them. I asked for and received a hand inspection of the four rolls I had in a zip-lock. Mailed the exposed rolls home from Key West.
