Virgin SpaceShipTwo crash 'a massive setback', says Branson

Sir Richard Branson has described the crash of Virgin Galactic's SpaceShipTwo as "a massive setback".

Talking to the BBC's David Willis, the Virgin chief said they had to: "find out what went wrong, and see whether that problem is fixable".

US officials have started to investigate why the rocket crashed over California's Mojave desert on a test flight.

One pilot died and the other was badly injured in the crash.
