Overview
The Koolhoven F.K.57 was a twin-engined, gull-winged monoplane built in the Netherlands as a personal transport for the Director General of Royal Dutch Shell. Only one was made, flying chiefly in Europe in the year before World War II, but destroyed when Germany invaded the Netherlands in May 1940.
