A study of the two-control operation of an airplane
A 1938 NASA technical report on aircraft control, studying how an airplane responds when operated with only two controls, prepared for aeronautical engineers and researchers. The four plotted pictures are time-history graphs of rolling rate, angle of bank, rolling moment and yawing rate, with curves labelled by coefficient values and shaded bands; a designer might borrow their clean line graphs, dense grid layouts and labelled axes as a model for technical data visualisation.
