The Do 27 was the first post-war aircraft to be built in Germany, where it flew for the first time in 1956. Reliable design, solid construction, versatile capability, economical operation and extraordinarily short take-off distance are the outstanding features of the Do 27. One DO 27H, identification D-ENTE, equipped with an unusual Zebra livery was registered on 26.11.1957 for the OKAPIA KG M M. Grzimek & Co in Frankfurt-am-Main. With this machine Michael and his father Dr Bernhard Grzimek, the legendary director of the Frankfurt zoo, took films of wild animals in Africa. At the same time the machine served as a observation plane in the Serengeti in Tanzania for researching and monitoring the threatened animal species and their migrations in one of the last African wildlife paradises. That resulted in some of the impressive takes in the most famous German animal film "The Serengeti must not die" which also received an Oscar for the best documentary film. On 10th January 1959 an accident happened. The aircraft with Michael Grzimek at the controls collided with a bearded lammergeyer vulture over the Serengeti and crashed.
