The latest is that Stephen Hawking wants to buy a ticket on Virgin Galactic: "I am not afraid of death but I'm in no hurry to die. My next goal is to go into space... Maybe Richard Branson will help me."
Something like this would be a huge public relations snatch for Virgin Galactic IMHO. A disabled reknown Cosmologist on a long dreamed flight to space is definitely something people will want to hear and watch about.
That and I do have to admit that I share Hawking's dream - as I'm sure many other space nutsos out there such as myself do. So the prospect of a disabled Hawking going into space lends credence to the little spark in us all that yes IT IS possible.
My bias admitted you can make up your own mind as to whether this had any real chance of happening.
