Hi,

as I think.

More accurately, "an artist drawing a jet-driven project" based on boundary layer control principles described much earlier by Professors Ludwig Prandtl (Göttingen) and Alexander Baumann (Universität Stuttgart). Jack Baumann was, of course, an American-born designer.

Alexander Baumann was the first ever professor of aeronautical engineering. During WWI, Baumann was chief designer for von Zeppelin's Versuchsbau Gotha-Ost (assisted by his protogé Adolph Rohrbach as well as Claudius Dornier and Hugo Junkers). Prof. Baumann's Progress made in the construction of giant airplanes in Germany during the war of Dec 1920 can be read here:

As for the Flight Global links, is anyone else getting '404' responses from their pdf Archives?
