Bullies...
Actually, the Germans bullied the Swiss. Although for many Black Forest dwellers, ZRH is the international airport of choice, they got up tight about the overflights (well above the few homes there) and got their transport minister to browbeat the luckless Moritz Leuenberger into agreeing to a very restrictive overflight policy.
There can be no comparison to the "visual noise"which the descending ships made over the Black Forest to the resulting fully configured powered approach at lower heights over the populated areas around the field. That's what you get when politicians with little technical knowledge negotiate complex issues.
As for "something for nothing", the Alpine transit concessions made by Switzerland can't be written off like that. In Austria you know all about this phenomenon too...
