I replied to your post in MISC, but since you've given it its own thread here, I'll post a reply here as well:
Glad to hear your interest. I guess you could say I'm a Challenger buff, but more from the mechanical/engineering/administrative angle. I don't know much about the personal lives of the crew.
When I hear "Challenger" I don't think of McAullife, Scobee, Smith or Onizuka. I think of the names Feynman, Boisjoly, Thiokol, Kilminster and Rogers.
In the future, might want to be more careful with phrases like "blow up in their face". Kinda hit me like an old disgusting joke people used to tell about Christa McAullife's eyes.
But I'm glad new people are finding interest in Challenger. I view it as the Titanic of our time. As soon as we start to get cocky, nature puts us back in our place.
For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

As for your question, I don't think there should be ANY manned space flight right now. All the money we are currently using to send people into to space could be put to far better scientific use.
If private companies want to send millionaires on atmosphere skimming joyrides, well, I guess that's fine.
