Armstrong Whitworth 27 "Ensign" commercial airplane (British) : an all-metal high-wing monoplane
A 1937 NASA Technical Reports Server record of an Aircraft Circular describing the Armstrong Whitworth A.W. 27 Ensign, a British all-metal high-wing commercial monoplane, aimed at airline and technical readers. The pictures are plain line drawings and photographs of the airliner, with cutaway views of its internal structure, frame layout and wing construction, offering a designer strong examples of technical diagram hierarchy, labelled callouts and stiff engineering linework.
