I once stopped a helicopter pilot from doing (almost) whoop-de-doos with me on board without saying a word. I just turned very green & he straightened up.I’d say the Decathlon pilot was lucky the guy didn’t puke all over his plane! First friend I took up after I got my license (back in high school), well... lets just say, thank goodness there was a barf bag handy. (And it was quite unintentional on my part!)
