My hat is off to pilot Mike Melvill, who stayed calm despite the spaceship performing 20 or so barrel rolls while the engine was firing. The previous test flight also had some control problems. This should remind us that space flight is dangerous. As various private companies continue there research and development, we should expect that there will be failures, and unfortunately those failures will cost lives. The pilots of these aircraft understand this risk, just like NASA's astronauts do. So hats off to these great teams!
I'll admit I didn't think the X-Prize could be won by its expiration at the end of this year, and we are one flight away from a winner.
