Who owns the sky?
As for airspace, I believe there are international laws about how high above a country you have to go to avoid the risk of being shot down - or generally complained about depending on the weaponry available.
Originally posted by KazetNagorraI think the land owner only owns a very small area above the land. Here in cape town you need permission from your neighbors before you build upwards because you might be blocking their line of sight. Also if you go a little higher you enter the airspace used by aircraft etc and I think the government controls that ie you cant tell planes not to fly over you, but the government can tell you not to fly your kite/hot air balloon in their airspace.
That depends on the legal system of course. But in practise I think it's usually whoever owns the patch of land beneath it, to reasonable limits.
Much higher up where the satellites roam its first come first serve.

At least according to this American federal court, the sky is public domain; as KN said, beyond the reasonable reaches of your property.
