100 years ago in my first year law school, in our "property" class we discussed, the traditional property law of "you owned everything above your property to the heavens" as modified by commercial aviation. At what altitude, did a property owners rights end. So, nations do not have "property rights" to deny satellites flying over their territory (as long as they are in "space") and individual property owners do not have the right to deny aircraft the right to fly over their property, again, usually assuming some minimum altitude.

Drones are requiring new laws to be made. I can deny a 6 foot person from my property under "trespass" law. Can I deny a drone flying at 6 feet? It does not seem to be clear. . .
