ALS-ridden physicist Stephen Hawking fulfilled part of his dream of space-flight by taking a ride on a specially outfitted jumbo-jet that achieves zero-G conditions by describing big mid-air parabolas. Looks like he's having fun too. Unless that's his "just dropped a huge load in my man-diaper" face. Oh wait, how insensitive of me - I don't think Stephen's bowels work anymore. Damn, that guy's messed up.
