I go back to the fact that people CLIMB over one-another to perform these missions. And the fact that I would jump on a space shuttle tomorrow. And like to think, that if given the time, right before dying like the astronauts did today, would say to myself: "Well...It's been a hell of a ride and well-worth the price".
I don't have what it takes to go through becomming an astronaut. Those who do are better people than me. And THEY build a better America. No robot can build anything like that.
I guess I wouldn't stop you ---myself --the claustophobia would get me, I don't even like airplanes so I guess i don't see the thrill. I remember feeling sorry as a kid for the little dogs and monkeys they used to send up in rockets.
