Re: You don't own the air above your ground
"Nope, it just says that navigable airspace starts at 500+ feet. There is no defined height of private ownership. The US court system's record for ownership is 83 feet above a property (United States vs Causby)"
Which means, per the Constitution, anything not claimed or forbidden by the Fed goes to either the States or the People. But since most States do not directly claim airspace, that means it defaults to the People.
