I don't think I possess any skill that anyone else doesn't have. I've just had perhaps more of an opportunity, more of an exposure, and been fortunate to survive a lot of situations that many other weren't so lucky to make it. It's not how close can you get to the ground, but how precise can you fly the airplane. If you feel so careless with you life that you want to be the world's lowest flying aviator you might do it for a while. But there are a great many former friends of mine who are no longer with us simply because they cut their margins to close.
