Virgin Galactic SpaceShipTwo: Eyewitness on 'horrendous' crash

Virgin Galactic's SpaceShipTwo appeared to explode after being released from a carrier aircraft at high altitude, according to Ken Brown, a photographer who witnessed the blast.

At least one person was killed and another was injured when Virgin Galactic's SpaceShipTwo space tourism craft crashed in a California desert.

The craft was flying a manned test when it experienced what the company described as "a serious anomaly".

Photographer Ken Brown said: "Everything seemed to be going normally when they came overhead.

"They released the space craft, lit the engine. And it's a little difficult to tell how long it was but it burned for a time, and then just exploded.

"It was quite horrendous."
