The first time I flew with my helo pilot friend and he "educated" me on auto-gyration. That was a bit nerve wracking....
Reminds me of my first flight in an OH-58 many moons ago. I made the big mistake of letting the pilot know that it was my first time up in a chopper. He dropped it from about 500 feet down to where we were low enough to have reached out and grabbed a handfull of grass and then put full pitch back on the main rotor and took it straight back up. And he - naturally - was laughing his a.. off.
