Mine was a tandem jump from a nice big twin engine King Air. All I had to do was slide my butt down this narrow bench to the open door and stand at the edge waiting for the boss to push me out.
The noise and wind as I stood there, maybe two whole seconds, gave me a good scare. Then we were out there and - gulp! - I just froze from the shock for a second, not even breathing. We were pretty high, almost 14,000 and the free fall was close to a minute. My ears were hurting after that, cause the wind is loud as hell.
Then after the chute was pulled, I was allowed to steer. "Pull this down to your waist" - Holy crap, those things turn on a dime! Great fun and would recommend it to anyone with a strong heart.
