I'd be very surprised to see any current aircraft go supersonic without AB.
If I am remembering correctly, the SP gets heavy MX and/or tech upgrades in Germany. There is a good documentary on it. It does. However, that work is done in Hamburg, not Stuttgart.

If you look at airport annual pax data, you can see passenger flows being higher inbound or outbound. That’s a very simple example of immigration flows inbound or outbound.

There is no procedure for certification of spacecraft for passenger transport.

I know what you mean. I sometimes hear faint jet noise, look up, and find the aircraft at cruise altitude. It's almost always a 77W or A343. The volume seems to be weather-dependent; it's most noticeable on clear winter days.
In Vienna, I would suspect that the 77W is from nearby Munich airport.
