To all of those thinking of doing one I would say do it! I did a tandem freefall last year and it was amazing. All over a little fast though (funnily enough).
Here's a video of my jump:
YouTube - Jim Falls to Earth
A few precursors though:
1) I had to get up very early to do it, so am as rough as old boots.
2) I've done it documentary style for all my fans, so there's a bit of camera phone footage and chat edited in, with some attempt at comedy.
3) The skydiving outfit is not very flattering.
As I'm falling, all you can see me say is "It's f***ing amazing!" over and over again. The feeling, and the view was overwhelmingly awesome.
I'd like to get my A licence, but I really don't have the time to invest in it as a sport.
