I was wondering how fast can you learn when you have lots of resourcies like, time, windtunnels, good coaching and a specific goal. I think fun jumpers do need at least C licence. For HALO I was thinking something close to 30 000 ft night or day.
I was wondering how many jumps before first real HALO jump. I'm talking about military personel, special forces of somekind. And how do you keep yourself current, jumping obviously is only a small portion of things to be current of.
