A Full-Scale Investigation of Ground Effect
This is a 1928 NASA technical report on aerodynamics, a full-scale study of ground effect on aircraft, issued as a government research document for engineers and aviation researchers. Its first picture is a line chart of lift coefficient against drag coefficient with curves for several test conditions, and its second is a grid of grainy photographic frames of an aircraft in flight against sky and cloud. A designer could take the sparse, technical chart styling and the cropped sequence of monochrome aircraft photographs as a model for clean data graphics and documentary image layouts.
