German post-war construction has developed along two definite, though closely interrelated lines, namely, the full cantilever and the semi-cantilever monoplane construction, which has been adopted for all passenger carrier cabin airplanes that are not merely conversions of war machines.

The production of the Fokker F-type monoplanes has created a new interest in passenger and freight transport by air as a commercial venture. Operators of air lines have found out at their own expense that the type of airplane which the war had left us, and even their commercialized descendants were as profitable in commercial air transport as a converted battleship would be for a transatlantic passenger line.

The Dornier C.III cabin airplane is the product of Zeppelinwerke Lindau and was designed by Claude Dornier, chief engineer of the firm. Herr Dornier’s previous efforts in allmetal construction will be remembered by our readers through the Dornier giant flying boats which were described in these columns at an earlier date.
