After the Anisari X-Prize, what happened with the competing spaceships?

I recall a handful of years ago, the now famous "Spaceship One" flew a triumphant flight into lower orbit, then repeated the feat two days later. It was a great day for sci-fi fans everywhere, watching a privately built spaceship go from dream to reality.

My question for you, is what happened to the other ships who were competing? I know there were numerous others, and at least one that was never built. I hope there were no "Epic Fails" where anyone died. But did they fly too? Were they all used? Did they just all get scrapped?

Maybe you know...
