American astronauts will get into anything, they'll even get into rocket systems that exploded on the launch pad during testing. They're a brave bunch, they really are.
There are two American astronauts stuck in space right now because the Boeing Dreamliner return capsule is stuck on the international space station; it won't detatch from the portal. I often wonder if it is a good idea to let private companies operate space missions. Is privatisation always the answer? I don't know.
