It is a remarkable achievement, but to get into orbit is going to need something capable of literally 10 times the speed of this -- and a whole lot more fuel, and entirely different design, using different materials. I wonder just how much of the technology in 'Spaceship One' would be transferable to such a craft. Very little I suspect, sadly we are still a long way from the days of affordable 'true' space flight.
Still love to have a go in it though.
