Burt Rutan

For the industry we're starting now, for suborbital flight, there is no destination, so the spacecraft you go up in has to be large and spacious. That's why SpaceShipTwo is much bigger than SpaceShipOne: It needs to be because you want those six people to be floating around and enjoying themselves.

There was a wonderful little short four-year time period when marvelous things happened. It started in 1908, when the Wright brothers flew in Paris, and everybody said, 'Ooh, hey, I can do that.' There's only a few people that have flown in early 1908. In four years, 39 countries had hundreds of airplanes, thousands of pilots.
