Focke-wulf F 19a "ente" Commercial Airplane (german) : a Tail-first High-wing Monoplane
A 1931 NASA technical report, drawn from the NASA Technical Reports Server, describing the German Focke-Wulf F 19a "Ente", a tail-first high-wing monoplane commercial airplane aimed at engineers and aviation researchers. Its pictures are grainy photographs and a line plan showing the aircraft from the front, rear, three-quarter and above, with wing outlines, engine nacelles and elevator details; a designer could take the stark silhouette of the canard layout and the crisp technical diagram style.
