It is one of my favorite airplane. Three Ju-52 were in service of the swiss army until 1981 (A-701, A-702 and A-703). It a very popular airplane - the swiss call it "Tante Ju" (aunt Ju), so they were saved from scrapping and are used since then for sightseeing flights. Because I live near the airfield where they are based, I can see them flying every weekend. They are very, very slow. I plan with some friends to charter one of them.
