A NASA-funded study estimates that if the price of a ticket to space approached $100,000, close to a million people would buy one. That's a $100 billion industry. Microsoft cofounder Paul Allen gave me $20 million in startup funding to go after that market.

The Russians did much bigger space launch vehicles for launching satellites and for getting men in orbit. They did that much sooner than America because America was very good at something else.

There will be a new industry, and we are just now in the beginning. I will predict that in twelve or fifteen years there will be tens of thousands, maybe even hundreds of thousands of people, that fly and see that black sky.

Achieving something that has never existed in manned spaceflight and that is high volume and public access.

Science is not about consensus, and consensus is not science.

Confidence in nonsense is required.
