The moment a skydiver was knocked unconscious during a 12,500ft jump has been caught on camera.

James Lee collided with another diver moments after they jumped from a plane at a skydiving site in Wiltshire.

He was rescued by quick-thinking friends, who grabbed hold of him and deployed his parachute.

Mr Lee said he "came around" as the parachute opened.
