How are planes protected from lightning

Airplanes and cars act like Faraday cages. Faraday cages are closed rooms or bodies that are encased with a metal grille or flat metal. The sheathing shields the interior from an external electrical field.

If lightning strikes an airplane or a car with the windows down, nothing happens to the occupants. However, the shock should be great, because the thunder in the immediate vicinity is very loud.

Even an airplane in the air is in principle protected from lightning damage. Damage can still occur on individual parts. These video recordings are from Japan. The plane was struck by lightning twice and later landed safely.
