Stephen Hawking is one of my favorite people. I love his books, lectures, and most especially his spirit. On Thursday he was given a chance to ride the 'Vomit Comet' and experience Zero G. Check out the stories here and here and also here and here! And, one final link to what he thinks about Humans and Space.
I saw the video of his trip on CNN and the grin on his face said it all. The report stated that the plan was for 6 instances of Zero G, with the possibility of ending it after 1 if Stephen wasn't comfortable..... He negotiated them into adding two more times for a total of 8 and they said he would have done more!
