Before someone flew, no one could specify just what the aeronautic motor should be able to do, except that, of course, it should be as light as possible and not stop in the air. Nor was there any demand for such an engine that would serve as an inducement to engineers familiar with engine production to build one. In short, while those few experimenters who were engaged in trials of balloons and gliding planes felt they might be helped if they could secure a proper light motor, no one felt sure it would be of service if produced, an dof course no one could say how light it should be, or what other characteristics should be incorporated, except that of reliable continuous running during a flight. Formulation of some of these specifications may be said to date from about the years 1901-2, when the Wrights, on the one hand, and Langley, on the other, found that existing engines developed lor other classes of service were unsuitable, By Charles E.
