I am not going to pretend that flying a spaceship will be as safe as getting in a 747 with four engines for a flight across the Atlantic.

I want to get to the moon. I want to go to Mars.

In any aircraft you fly, you always think about what can go wrong, and you plan for it in advance. You always have back-up plans.

I was a bit challenged when I was younger to stay on the right path.

People say, 'Where do you live?' and I say that theoretically, I live in London, but basically that's just where I go to change my suitcase. Otherwise, I'm always flying somewhere.

Fear follows crime and is its punishment.
