I was in the southern Black Forest a lot this wonderful summer - mainly by racing bike - and I saw quite a few ZRH inbound flights. I say saw, because I hardly heard anything. When you compare flights over 5000 ft clean and in idle thrust in approach with the racket you get with gear, flaps and thrust spun up at low height over the newly affected regions, there is no comparison.
Very true Few Cloudy, the noise complaints are indeed very artificial in nature.
But hey, now that Swiss Int. Air Lines has chosen for BA´s One World and not for Lufthansa´s Star Alliance, I guess that ´zee´ Germans are smelling blood and are going for the kill.
Who needs a Swiss HUB in ZRH if Lufty can fly all the pax to MUC and FRA? It´s just one more nail into the coffin of Swiss...
