The De Havilland "Comet" long-range airplane (British) : a low-wing cantilever monoplane
This is a 1934 NACA aircraft circular, issued by the United States National Advisory Committee for Aeronautics, describing the British De Havilland Comet racing monoplane for aviation engineers and researchers. The pictures are plain black-and-white technical line drawings: a general arrangement with top, front, and side elevations and dimension lines, plus exploded and detail views of wing structure and landing gear, which a designer could use as clean diagrammatic references for mechanical cutaway illustration.
