I would, but I gave up my seat to Stephen Hawking. At the celebration of his 65th birthday on 8 January, 2007, Hawking announced his plan to take a zero-gravity flight in 2007 to prepare for a sub-orbital spaceflight in 2009 on Virgin Galactic's space service. Billionaire Richard Branson pledged to pay all expenses, costing an estimated £100,000. So far as far as I know, he hasn't taken off.
