The Junkers "G 38" commercial airplane (German) : a giant high-wing monoplane
This is a 1930 NACA Aircraft Circular, issued by the United States National Advisory Committee for Aeronautics, describing the Junkers G 38 giant high-wing commercial monoplane for aeronautical engineers and aviation researchers. Its pages are photographs of the aircraft's internal structure, wing surfaces, cabin instruments and a dimensioned side elevation, showing riveted corrugated metal skin, tubular and truss framing, and bare industrial interiors that suggest mechanical texture and structural pattern for a designer.
