I have made hundreds of jumps over many years (exact #s are classified! :)
This jump has been the talked about for a very long time...long time, but why was it never done before?
IMHO, until fairly recently, skydiving was inherently dangerous; but gear improvements over the last 25 years have made it safe. A friend of mine has made over 4,000 jumps and never had a malfunction. Secondly, nobody had the money to get a circus tent, or had the balls to try this jump.
My money says the guy will do it without breaking a sweat.
Do you think he can land within the borders of the net?
