My GF's a lifeguard, she can tell when peoples are faking drowning, she can actually tell they'll do it before getting in the pool. Back when I did volunteer work at the CNM, I could spot english speaking patrons before hearing them talk, and I was right like 92% of the time... it'S kind of an instinct, and kind of knowing what to look for.

I guess the whole point of my original post was that the airport security people might have been alerted that something was about to happen. But they didn't know where or when. I can't think of any other reason for stepped-up security at a small airport like Knoxville.
