The Derwitzer Glider was a glider that was developed by Otto Lilienthal, a German pioneer of aviation who became known as the "flying man", and on which date, his glider stalled and he was unable to regain control?
Derwitzer Glider The Derwitzer Glider was a glider that was developed by Otto Lilienthal, so named because it was tested near Derwitz in Brandenburg. When flown in 1891, it became his a very early successful design able to carry a person and the one of the first successful manned aircraft in the world. He made flights of up to 25 metres (80 feet) in it.
Hans von Ohain Hans Joachim Pabst von Ohain (14 December 191113 March 1998) was a German physicist, the designer of the first "operational" jet engine. His first design ran in March 1937, and it was one of his engines that powered the world's first flyable all-jet aircraft, the prototype of the Heinkel He 178 (He 178 V1) in late August 1939. In spite of these early successes, other German designs quickly eclipsed Ohain's, and none of his engine designs entered widespread production or operational use.
