The most amazing experience, ever!!
I had the most AMAZING experience today. There's a company called Zero Gravity that flies a Boeing 727 along a parabolic flight path that basically makes you weightless in the cabin.. It's what astronauts train in to get comfortable with space, and how they filmed the space scenes in the Apollo 13 movie..
My buddy did it a while back and thought it was incredible, so he set it up for a bunch of us to try it, and he was right.. it was insanely cool!! I don't have any pictures or video from it yet, but hopefully I'll get it soon so I can post a pic of myself floating upsidedown.
There is more information and some promotional videos at their website. It's pretty expensive right now, but hopefully in 10 years or so commercial space travel will be viable (seriously!) and it'll be something we can all do over and over again.
