Well that didn't last long. I had never heard of Rangsdorf. It's just south of Berlin and has been unused since the Russians left in 1994.
Rangsdorf is a municipality in the district of Teltow-Fläming in Brandenburg in Germany. It has an airfield [up to 1940 a genuine commercial airport] from where on 20 July 1944 Claus Schenk Graf von Stauffenberg took off on his fateful attempt to assassinate German leader Adolf Hitler at his military headquarters in East Prussia, the Wolfsschanze. Reich Minister of Armaments and Ammunition Fritz Todt was killed in a Heinkel He 111 crash departing the airfield on 8 February 1942.
I'll wait for sycamore to wake up!
