Donner: (voice-over) You would think that there'd be a sadness when you start to pull away from Earth. An ache for the mountains, what's left of the beaches, for the sweet smell of fresh air. My guess, there's a little bit of that. But when you're an astronaut, you start asking yourself questions like - How the hell did I get here? Was it hard work? Fate? Was it the hand of God? You ask yourself - Why am I one of the lucky suckers leaving, not one of the poor bastards being left behind?
Donner: (voice-over) Sometimes, I think the only natural selection happens in a Petri dish. But it's in a Petri dish, that's not really natural, is it?
