Somehow a local script in workspace?

I was looking at an airplane model, when I saw that it had working local script within a normal script.
How does that work? I know the local script was for controls, which would be very useful for me.

LocalScripts can run if they are a descendant of a player’s Character.

The Script probably copies the LocalScript into the character e.g. when the player sits in the driver seat, at which point the LocalScript copy starts running.
