We go up just into space - space is most commonly accepted to be 100 kilometres above the earth's surface, and we go up just beyond that to about 350,000 ft.

I watched the moon landing as a boy, and I thought that was the most exciting thing ever, going into space, orbiting Earth and exploring other planets. That looked fantastic.

I cannot wait to get up there and experience space travel for the first time. It will be a dream come true.

For Virgin Galactic's customers, it is transportation to the most amazing experience of their lives. I very much look forward to sending some Scots into space.

I thought any chance I had of space travel would be military or government-controlled.

This whole earth which we inhabit is but a point in space. How far apart, think you, dwell the two most distant inhabitants of yonder star, the breadth of whose disk cannot be appreciated by our instruments? Why should I feel lonely? Is not our planet in the Milky Way? This which you put seems to me not to be the most important question. What sort of space is that which separates a man from his fellows and makes him solitary? I have found that no exertion of the legs can bring two minds much nearer to one another.
