20,000 Show up for X-Prize Expo

Zacharski writes to tell us that the X-Prize Cup Expo was held Sunday in Las Cruces New Mexico in front of about 20,000 people. John Carmack was there with his team from Armadillo Aerospace. From the article: "Armadillo Aerospace got their rocket-powered, vertical takeoff, vertical landing vehicle off the ground. Blasting off into the sky then hovering for a few seconds, the craft began lowering itself to the ground - but tipped over on touchdown. The wet ground due to overnight rain was the cause, although the craft appeared undamaged in the fall. An internal hose was punctured, however, causing subsequent flights to be scrubbed." The expo also ended with quite a bang when Starchaser's Churchill Mk2 rocket engine blew up.
