The land includes:
|•||The earth's surface|
|•||Everything under it (all the way to the center of the earth)|
|•||Everything on it (everything that is appurtenant)|
|•||Everything above it within limitations (all the way to the sky)|
Court rulings have pretty much allowed planes and other aircraft to pass over a person's land without permission so "All the way to the sky" must be taken with a grain of salt.
