Last July Virgin Galactic’s SpaceShipTwo (SS2), the VSS Enterprise, made its first manned flight. For the duration of that flight, the spacecraft remained attached to its jet-powered carrier aircraft. But over the weekend VSS Enterprise left the protective grip of its mothership, VMS Eve, to successfully achieve its first manned free flight. Released from VMS Eve at an altitude of 45,000 ft (13,700 meters), VSS Enterprise glided for 11 minutes before landing at Mojave Air and Spaceport, successfully completing the two main goals of the flight.
