Good point. I sometimes think about a bike taking a jumper faster than terminal velocity, and try to imagine the tremendous force trying to rip the rider off the bike. S C A R Y! It wouldn't be much fun to be a hundred feet off the ground at 130 mph and get ripped off the bike like an autumn leaf!
Sometimes we talk about terminal velocity and the problems that will occur as Capes goes faster and faster and approaches terminal velocity. The drag is so strong at that speed. I remember doing 135 on a street bike, sitting upright and WOW, was the drag strong. If I would have tried to put both hands above my head, the drag force would have ripped me off of the bike!
I do think that if it was possible, it would be super aerodynamic for the rider to do a Superman at such speed, but one problem would be fighting the drag to get back on the bike! Another problem would be using the rear brake to adjust the pitch.
