It's been awhile since I've flown but I recall the flight attendants pulling the drink cart when we passed over a dry state. It would seem that at least that airline considered States Rights when passing through sovereign territory.
As to the hypothetical pregnant astronaut, I would think that a 5g liftoff would be enough to insure a birth while still in sight of the launch site.
Interesting legal question. Actually, this has come up in Case Law before.
Dry states (and states that extract excises) have tried to ban/tax airliners flying over their states and serving alcohol. I believe the most recent example was New Mexico
Another famous case law pertains a fugitive from Texas (where he had warrants pending). He was on a domestic flight transiting Texas airspace (just transit). The plane was forced down and he was arrested
