The Short "Scion Senior" commercial airplane (British) : a four-engine high-wing cantilever monoplane
A 1936 NACA aircraft circular from the NASA Technical Reports Server, issued as a technical report for engineers and aviation specialists, describing the British Short Scion Senior four-engine high-wing cantilever monoplane. The pictures are plain black-and-white engineering drawings: a cutaway with numbered callouts and detail insets, plus three-view general arrangement drawings with a data table. A designer could draw on their clean line-art, labelled diagram layout and typewritten caption style.
