The first ever visit of Soviet aircraft to Switzerland, flying in a delegation to demand the return of Soviet citizens who were somehow interned in Switzerland during WWII. Built by Douglas Oklahoma the front C-47, US serial 44-76715, was delivered to the Soviet air force as late in the war as April 1945. To civil on 28 April 1945. It seems to have washed-out white titles. The C-47 parked behind is CCCP-Л960 (c/n 26336 ex 43-49075) with what looks like a roughly painted out red star on the tailfin. CCCP-L976 / CCCP-Л976 came in the following day. Photo from: ETH-Bibliothek Zürich
