The only states I have heard of that are moving to this overflight information request are the United States. There's some talk about it in the European Union. These are two entities that have very robust democratic institutions. If a non-democratic country were to ask for that information, I believe either the regulations would be changed or the act would be changed, depending on what is necessary. But for the moment, as I understand, that's hypothetical.
