Regarding airspace, I believe the courts have already ruled that air space is public as long as it doesn’t interfere with the private ground use or something like that.
Sounds reasonable, though very vague. What one person's definition of 'interfere with' can differ greatly from another's. There are people who'd claim a jetliner leaving a contrail interferes with their peaceful view of the sky. Likewise simply hearing a plane overhead, no matter how faint, can ruin some people's tranquility of an otherwise peaceful setting. This isn't to mention a plane over public land can be noise pollution to those on private ground.
I wouldn't doubt that lawsuits concerning plane use on public ground and the resulting noise become more common in the future. It is a huge, huge issue in AK.
