High up in the sky...

Today there is an airshow in a village near us...
It's called "Volkel in the clouds"... Volkel in de wolken
There are a lot of things to see or do.
We are not going to the show, but I think it's nice to see the planes arrive at the airbase at Volkel. I walked a bit around the airbase, met two nice people from Germany. Who could tell me a lot about the arriving airplanes...This is a very special plain they said Gyroflug-sc01

I do not know what kind of plain this is, if anyone knows, tell me...
