Stinson Commercial Airplane, Type S M-1
This 1927 NACA Aircraft Circular from the NASA Technical Reports Server documents the Stinson commercial airplane, Type SM-1, for engineers and aviation researchers. Its photographs show cockpit controls, engine and undercarriage details, and frame-and-strut structures from early aircraft testing. A designer might take from them the mechanical clarity of period aviation documentation, with dense technical plates and orthographic line drawings.
