I did a few jumps just to get aclimated
When I was a kid I knew I'd be flying and I also knew I'd be flying acro. So like lot of us I'd read aviation magazines and I began to notice that a lot of pilots who wrote articles about mishaps they had, and who had to leave the airplane *all* said that they hesitated before jumping because it was a scary proposition. When I was in college, I had the opportunity to do a little skydiving at a local skydiving school. I decided I would do enough jumping such that there would be no hesitation due to this being my first jump, if I had to leave the plane. So my skydiving logbook has 29 jumps. Enough to get me into 15 second free falls, My first jump...I was petrified until it was my turn to jump and then I was too busy following the commands to be afraid. By my 8th or 9th jump I was able to sit in the open door with my feet dangling out in the airstream, in total comfort. After all - if we hit a rough patch and I was thrown out of the airplane...I'd just hit a hard arch and pull the ripcord. So nowadays I am perfectly comfortable and psychologically ready to leave the plane if that's the move to make. I recommend a few jumps to anyone who want's to be just that much more prepared.
