Logically air gapped :)

AWS likes to redefine things.

Air gapped means... there is nothing except air in the gap between systems.

A physical tether would defeat it.

Now, I pedant could start talking about wifi, but air-gapping is a concept older than the internet. (It stems from plumbing where there's air that prevents back leakage of contamination).
