Designed by Walther Rethell, who had previously worked with Fokker, the Arado V.I was a small airliner of mixed construction, the V probably standing for Verkehrsflugzeug. It could carry four passengers in the cabin, but because of its good range Lufthansa used it on experimental mail flights to Irkutsk, Constantinople and Seville. In December 1929 it arrived on Tenerife but on the return flight, via Cap Juby, Seville and Marseille, it crashed in thick fog near Neuruppin, and two of the three crew were killed.
