Watch: Richard Branson's new spaceship fly solo for the first time

Source: Virgin Galactic. More than two years after one of its spacecrafts crashed, killing the co-pilot, Virgin Galactic sent its SpaceShipTwo back in the air this weekend for its first "glide flight." Taking off from the Mojave Air and Space Port on Saturday morning, the spacecraft flew for about an hour tethered to the belly of its mothership, known as WhiteKnightTwo. Then pilots released the spacecraft, which did not fire its engines but glided safely down back to the ground.
