Virgin Galactic's VSS Enterprise completes first solo glide flight

It completed its first flight with a crew on board back in July, and Virgin Galactic's VSS Enterprise (a.k.a. SpaceShipTwo) has now crossed what's unquestionably its biggest hurdle to date: the first solo glide flight. That happened early Sunday morning at the Mojave Air and Spaceport in California, where the VSS Enterprise took off attached to the mothership and then separated at an altitude of 45,000 feet, after which it was freely piloted by Pete Siebold and co-pilot Mike Alsbury for a full eleven minutes before safely landing on the runway (another first for the spaceship). Oh yeah, there's a video -- head on past the break to check it out (along with the official press release).
