We have the ability, at such high fidelity, to simulate the physical world through computers. But when the spiritual world or human behavior comes into play, we don't have a very good model for that at all.
I would rather people understand that there is a very, very fortunate American who was given the opportunity, and was in the right place at the right time to have the moment of a lifetime. My mother was born - her name was Marianne Moon. And she was born in 1903, the year that the Wright Brothers first flew.
I was motivated to improve the U.S. strategy of going back to the moon in 1985. That's a long time ago. Going back to the moon would be a great achievement for tourism adventure flights.
