Well, a few years back, I had the opportunity to take a couple of
lessons in an R-22. I'm a power and glider pilot of no great
accomplishment, but that made me feel that not more than 20% of what I
know about flying applied to helicopters. After 2 hours, I was just
barely getting the ability to hover. I could handle it OK in the air,
but not very well near the ground. It seems like learning to ride a
bicycle: When you can't do it, you don't see how you can learn to do
it. When you can do it, you don't see what's the big deal. And you
can't tell anybody how you do it. After that 2 hours, I was just on
the edge of feeling that I was about to get it.

But, it's as much fun as anything I've ever done with my clothes on,
being equaled (but not surpassed) only by flying a glider.
