This museum (situated in the north-eastern corner of Switzerland on the civil airport of Altenrhein) is a private enterprise manned with volunteers only, open on Saturday- and Sunday afternoons. The museum claims that their entire collection is in a flyworthy condition and indeed, most aircraft bear, except for their previous military markings, a civil registration as well. Frank visited the museum in May 2011.
In 1988 Hans and Frank were in Switzerland to watch the “Flugmeisterschaften” (Air Championships) of the Swiss Air Force. The event was held at Dübendorf AB, where an airshow was attached to it on 27 August. This gallery shows you some of the military a/c participating.
