Challenger, Columbia, Apollo 1...Fifteen of our finest gone. That's just ours, we don't know how many Cosmonauts for certain, but at least four.
I'd rather have the problem get caught and the launch delayed than not.
It really does take the best people to say, against all pressure that may exist, "No, it isn't safe, don't launch."
When I was a child, I wanted to be an astronaut. Just like so many other children.
Then I read about Gus Grissom. And I decided I would keep my feet on Earth for my entire life.
I hope the stranded astronauts will be able to see their family and friends very soon.
