Virgin Galactic tests SpaceShipTwo

The skies over California's Mojave Air and Space Port are serving as the proving ground for the WhiteKnightTwo, the massive mothership being tested to air-launch commercial spaceliners on suborbital flights. A third test flight of the huge carrier craft — which looks like a giant catamaran for the sky — is deemed as "imminent", said Will Whitehorn, President of Virgin Galactic."
