また飛び入りしてゴメン〜。"Luft-Netzwerke"..I don't know if it could be a German word. Today it recovered bluesky after some cold and snowy days, and could see the Sun looks alike to be caught by the Spyder net made of airplanes' contrails. Could imagine "Luft-Netzwerke", all cities like Roma, London, Paris... are within only one hour's flight distance so I may fly free wherever. But actually I have to drive for 6 hours today on Autobahn.
