J.Herris - Otto, AGO and BFW Aircraft of WWI /Centennial Perspective/ (37)

The Otto biplane shown at Johannisthal is one of the first Otto airplanes built. The engine was a 50 hp Daimler four-cylinder design and the radiator was mounted behind the engine. The fuselage was fabric-covered, the under-carriage had a large skid frame with two wheels. Built 1909/1910, it had a span of 13 m.

Otto-Flugmaschinenwerke on the Oberwiesenfeld near Munich (1911-1915). Hangar with an Otto mono- and biplane.
This photo of the Gustave Otto Flugmaschinewerke was scanned from Udet's book Mein Fliegerleben. In 1909, 13-year old Ernst Udet and some of his buddies (aged 10 to 13) formed what they called the "Aero-Club Munchen". Each Wednesday they met in the Udet attic to build flying models from scratch. When Gustav Otto, the son of Dr. Nicolas Otto, started building aircraft in his wooden sheds at Milbertshofen, the group of kids would organize outings to the Gustav Otto Flugmaschinenwerke. They would peer through the fence for hours... that is what you see in this photo. Later, of course, Udet would learn to fly there as well. The group of little boys peering through the fence no doubt includes Udet but which one is not known. (Greg VanWyngarden)
