This illustration of Langley's Aeroplane dates to the early 1920s. By definition an aeroplane is a flying machine that is heavier than air and sustained by aid of propulsion from a source of power and the lifting action of the air on moving planes. Interesting experiments in this field were made by Otto Lilienthal, Hiram S. Maxim, and Prof. S. Langley near the close of the ninetheenth century.
