I caught an inboard flap with my face a couple months ago. They rigged the cable assy backwards so the outboard side of the inboard flap hung lower than it should have. We had it slid up on the track but the wind caught it and it slid off, whacking me in the mouth and chin. I immediately hoped I still had my teeth, which I did, but I got a fat lip and a nice mark on my chin for a couple of weeks.
