First thing I noticed was the wind took my breath away. It was hard to breath for a quick second, but you adjust quickly. I was also a little stunned for a second during the freefall, but it is AWESOME! The most anxious part of the whole trip was the right up in the airplane. I couldn't wait to do the jump! I highly recommend it for thrill seekers.
It was fun, I did it on my lunch break when I was like 19. Super adrenaline rush. Definitely can list a few things that were much better feelings, but it's worth it to try at least once.
