That's not safe by any stretch of the imagination. Stability is the first goal of skydiving. That's like saying I want to learn to drive so I can spin my car out on the highway when its wet.QuoteSorry if it sounded a bit noobish. What I ment was like swooping around and experimenting what body position did what at that kinds of speed.
On a side note. When I was first learning to drive I was tought how to spin a car in a controled manner... oversteer is fun, and it was also on a highway and it was raining.
