Virgin Galactic crash: Slowing device 'deployed early'

A safety device on the Virgin Galactic spacecraft that crashed on Friday killing a test pilot had deployed early, US investigators say.

Air safety chief Christopher Hart said the "feathering" device, designed to slow the craft on re-entry had been unlocked by one pilot.

However it then activated without a command from the pilots.
