Booom! You could hear the hollow echo reverberating through the whole airframe of that 152. The poor guy buckled and almost went down on his knees.
I ran over to make sure he was ok. He was just a little stunned, and then embarassed. He had a little crease up near his hair line, but amazingly, no blood. He must have just hit the fiberglass wingtip fairing instead of the aileron.
I told him about the last time I wore a ball cap around my 182. It was a couple of months after I got it. I made real solid contact with the back of the flap, but recovered in a few minutes. I was by myself and didn't think much of it. A half hour later, I felt something wet under my headset. It turned out to be blood running down through my hair. I'd removed a stripe of hair about 3 inches long, too.
Moral of the story: The ball cap stays in the plane at all times! If you're gonna wear a ball cap around a Cessna, just make sure it's red. That way, the blood doesn't show.
