Interesting side story: Our trip across the alps almost ended right were the picture was taken. Directly behind the summits you see in the picture is a restricted Italian military area. The air traffic controller (ATC)* for Austria (sitting in a cellar somewhere in Vienna) already warned us that our heading would directly lead us to that no fly zone. Not having much control over our flight path, our pilot tried to climb and descend in order to catch a wind which would take us in another direction. The winds, however, weren't in our favor and only knew one heading - towards the military controlled airspace. The pilot already started the descent in order to land in the foothills when he said: "What the heck, let's give it a try and contact the Italian military ATC." Said and done, we were granted permission to cross the restricted area and continued the last part of our journey. Maybe the fact that it was only two days after christmas influenced the military ATC to be generous . :-)
