I made a few jumps during the summer and it was incredibly fun. At one time or another in their careers, skydivers have to cope with fear. It takes time and experience to learn to manage that fear. Surprisingly, students often discover that their scariest jump isn't their first. Their second jump is often the most gut-wrenching, or perhaps their fifth or fiftieth.
Fear also increases as the time between jumps increases.
Getting back in the air after any sort of layoff is guaranteed to churn the stomach. Save enough time, money and good weather so you can jump several times a day for several days in a row. Expect to be really petrified on the first jump of that sequence, especially during the ride to altitude. But, more than likely, you'll land from that jump feeling quite enthusiastic about making another. You'll be much more relaxed on that next jump.
