I know the atmopshere is much thinner from where he is jumping... but 500 plus? for everything i grew up learning about terminal velocity and humans and whatever.... doesnt sound right to me.

Terminal Velocity is determined by mass and drag. So a human in a random posture, your friend is right the terminal velocity is around 120MPH. But if you decrease the drag, by going into the bullet position, terminal velocity increases to 200+MPH.. combine that with the thin atmosphere, that's how he can achieve the necessary speed to hopefully break the sound barrier.
