If you see something, say something

2 hour flight delayed 1.5 hours because woman thought man doing math was a terrorist:

Economist Removed from American Airlines Flight for Doing Math

The pilot comes to me and asks me out of the plane. There I am met by some FBI looking man-in-black. They ask me about my neighbor. I tell them I noticed nothing strange. They tell me she thought I was a terrorist because I was writing strange things on a pad of paper. I laugh. I bring them back to the plane. I showed them my math.

It’s a bit funny. It’s a bit worrisome. The lady just looked at me, looked at my writing of mysterious formulae, and concluded I was up to no good.

The lady did not re-board the flight, though it’s not clear whether she was held back or if it was her decision. (via Instapundit)
