Outstanding among the delightful collection of KZ types kept at the Danmarks Flymuseum is the KZ IV twin-engined ambulance aeroplane from 1944, one of only two built. Considered by the museum as one of their most prized exhibits, KZ IV OY-DIZ was designed and built for the Danish flying ambulance service known as 'Zonen' and benefitted from the concession allowed by the wartime occupying German forces for medical flights. Powered by two Gipsy Major X 130hp engines, it possessed excellent short-field performance. It crashed in 1979 but after an extensive rebuild, remains in flying condition.
