Switzerland. Seems like to make a walk in the past, in the years of the cold war. An old base of SAM surface to air missile Bristol Bloodhound (BL-64 Swiss Name) could be visited in Switzerland in the region of Zug (open air museum: http://www.bloodhound-museum.ch/). We took in the last days, with my friend Alessandro, a couple of pictures with our Mavic Pro and Phantom 3. An old (2013) but very interesting article from NZZ (Neue Zürcher Zeitung) could you read here: https://www.nzz.ch/schweiz/von-schwestern-und-raketen-1.18177920.
