The inhouse development team of Aerosoft - one of the major distributors in flightsim business - has done some pretty solid work. European Airports like Zürich, Berlin and Split have been recreated and can now be enjoyed in X-Plane as well.
Known for their top notch european sceneries the norwegian developers released several famous airports like Pisa, Svalbard and Torp. And the best: They are coming to X-Plane as well!
Although Volker is "weekend" developer only he would have the skills to run scenery development as his first occupation. With Heringsdorf and Magdeburg (Germany) he raised up the quality of freeware sceneries to an incredible level.
