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 first design able to carry a person, and after Sir George Cayley's glider, the second such aircraft in the world. He made flights of up to 25 metres (80 feet) in it.
