Watch the moment an F-16 saves an unconscious pilot from hurtling to his death

People have been amazed by footage released by the National Guard in America of a fighter jet taking over from a pilot who had passed out from G-forces.

Almost 300,000 have viewed the clip released by the Arizona Air National Guard yesterday of a training flight diving steeply as an unresponsive student pilot loses control.

The recently declassified Air Force footage shows what happened after the trainee pilot had been put through more than 8Gs of force from a tight manoeuvre, making him lose consciousness.
