The secret of my success is that I always managed to live to fly another day.
~ Chuck Yeager
In 1966, NASA took over in space, and it has been a bureaucratic mess ever since.
You do what you can for as long as you can, and when you finally can't, you do the next best thing. You back up but you don't give up.
You don't concentrate on risks. You concentrate on results. No risk is too great to prevent the necessary job from getting done.
I was always afraid of dying. Always. It was my fear that made me learn everything I could about my airplane and my emergency equipment, and kept me flying respectful of my machine and always alert in the cockpit.
