I don't mean to sound like this I'm trying to out do you guys but there is a friend of mine named Elmer Helfert who lives in Chicago, and he put a 20 FOOT groove in the runway with a Giant Stinger going at full throttle. It was really neat to hear about it and then to see it was something even wilder! According to what I've herd from some of his other friends who have known him longer than I have, claim that he used to walk pattern ships across the field back twenty years ago.
