After the war Stark, like many of the young men whose lives had been torned and transformed by the conflict, became somewhat of an adventurer. He flew for a while with Polizei-Fliegerstaffel 1 at Schleissheim, then as a test-pilot for Dornier. After that he went to South Africa only to return to his homeland in 1926 - a hard year of inflationand soaring unemployment - where he painted advertaisements, and even became farmer for a short while. Pressed by financiel difficulties and driven by his strong desire to fly again, Stark joined the secret German airforce with the rank of Oberleutnant. During the second World War he commanded an airfield in Italy. He died in 1982.
