Wings turn Virgin Galactic spaceship 'from rocket to glider'

Virgin Galactic have been building a new space plane in a hangar in the desert in the US.

Eight months ago in October 2014, Virgin Galactic's space plane crashed in the Californian desert killing one of the pilots.

The current project has been going on since 2012.

The BBC's transport correspondent Richard Westcott explains how the aircraft's wings operate.
