Hans-Jörg Dau, born in 1967, graduated in aerospace technology. Following his basic course in mechanical engineering in Hannover he studied aerospace technology in Braunschweig where he was already able to present independent research developments. He was granted the German and American patent for the development of a new fuel level measurement method for increasing air safety, and in 2000 he was awarded the Berblinger Prize for innovative developments in aviation. Inspired by his grandfather’s entrepreneurial spirit, the active pilot and Investigator for the German Federal Bureau of Aircraft Accidents Investigation founded DAUtec GmbH in 2003. Still in the same year, Hans-Jörg Dau established dauair AG which existed until August 2006. By founding dauair Verwaltungs GmbH, Hans-Jörg Dau carries on the concept of a regional airline.
