So years ago, I was asked to start to sell this program, and while I was doing that, I was put in front of a panel at NASA, as you might sort of imagine, a bunch of people in suits and white shirts and pencil protectors, and I did this sort of crazy, wild, "This is all the next great thing," and I thought they would be blown over, and instead the chairman of the committee just looked at me straight in the eye, and said, "So what's the big idea?"
