Vickers "Viastra I" commercial airplane (British) : a high-wing all-metal semicantilever monoplane
This is a 1930 NACA Aircraft Circular, issued by the United States National Advisory Committee for Aeronautics, documenting the British Vickers Viastra I high-wing all-metal monoplane for aeronautical engineers. Its pages are packed with technical photographs and drawings of the airframe's structure, including the cabin interior, landing gear fittings and wing bracing details. A designer could draw on the orderly grid of close-up mechanical photographs and line drawings as a model for presenting engineering detail in a clean, documentary way.
