How Does a Plane Land Itself in Zero Visibility?

How can a plane land itself in fog so thick the pilots can't see the runway? Radio signals guide it down and tell it how high the wheels are. In fog like that, the pilots watch closely while the plane does the landing. See how it finds a runway nobody on board can see, by riding an invisible slide in the sky. Then see what happens when the autopilot breaks, and why a perfect landing can still leave the plane stuck. Find out how it works, in this drawn explainer. Along the way: the balance knob on your car stereo, and the foggy day that cut Heathrow from 60 landings an hour to 30.
