The understanding of a travel or business aircraft began to change in the 1930s and the four-seat FK.57 twin was built for Frits de Kok, the general managing director of Royal Dutch Shell. The sole example first flew on 20 June 1938. Three months later it took off for a trip to the Far East, but De Kok and pilot Hein Schmidt Crans turned back in Karachi because of the Munich Crisis. The aircraft was not requisitioned by the Dutch army and must have been destroyed at Ypenburg in May 1940. Photo from: Pabo collection
