I did it once, a static line jump from 4,000 feet. When it was my turn to jump, it was the scariest thing ever, then the jump master said "get the #%*& off my plane" and you jump, say a quick prayer, look up and see your parachute is open and it's exhilaration.
The view is amazing as you come back to earth and they guide you in by one way radio, telling you which toggle to pull. Then I landed and they were yelling at me to stay down. I landed a foot off the runway and the wing from a glider went a couple feet over my head.
Overall it was cool experience and a box checked off my bucket list, I never did it again though.
