I saw at another forum that a Kamov KA-32 helicopter of Heliswiss will do some construction works (place an antenna) at the
Florianturm in
Dortmund at the 07th (and 08th) of september. Aircraft will be refuelled in the
Westfalenpark. And I can say, it is a very impressive helicopter, see this picture ....
See ya
