Re: I think it's a slippery road to assert the underlying terrain has jurisdiction
"This is a classic attempt to treat law as a pure logic exercise built on axioms established too many years ago when things like people flying were just mythic tales. A more pragmatic approach would be a better solution."
Maybe, as far as the USA is concerned, Federal law should apply when "in flight", ie above whatever the legal height limit is for landowners claims to "airspace". Likewise for any other country which has a similar local/State law system.
