Dream a big dream
Charles Krauthammer says it time to dream higher:
The risk of catastrophe for a commercial jet is 1 in 2 million. For a fighter jet, it is 1 in 20,000. NASA's best estimate for the shuttle was 1 in 240. Our experience now tells us that it is about 1 in 50.That is a fantastic risk. It can be justified -- but only for fantastic journeys.
