did I touch a nerve? ... these seem like pretty obvious questions ... when the Challenger blew there had already been severe problems with O-rings nearly burning through ... at least two Thiokol engineers were screaming about the temperature when Challenger was to launch ... and in the end it was concluded they ignored their warnings ... these are valid questions to ask when people die and expensive equipment is destroyed ... and other people have to risk their lives ...

Bobby, space travel is tough stuff. You can't pull over and change a tire. It's also dangerous; there are a thousand ways to die if something goes wrong.

We have some the best minds in the country running our space program. 17 people have lost their lives in almost 40 years. Everyone of those people fought a 100 others for the chance to go. I think that's an excellant record. NASCAR's is not that good.
