Knubel was one of the many German manufacturers to build aircraft to the Taube configuration. The Knubel Taube was the first German aircraft to appear in "invisible" finish (Cellon). Built in 1913-1914 the second machine is illustrated here. The fuselage was painted light blue to further reduce its visibility while in flight. When it was flown at Johannisthal it received the nick-name "Greenhouse." (Peter M. Grosz collection, STDB)
