Thanks to 30 min in tunnel I was able to finish AFF in four jumps. I can't imagine myself jumping without a tunnel training, it helped me a lot. The first three exits I was so nervous, that I didn't want to continue in the sport. My feelings was changed after the fourth jump, when I had to manage everything by myself and then I enjoyed my first solo.
