In Germany, another man interested in flying was experimenting. Otto Lilienthal, in the year 1890, built for himself a queer-looking glider which resembled nothing so much as a bat with huge wings. Remember Leonardo da Vinci’s idea? To his bat wings Lilienthal attached a tail-like rudder for steering. For his own support on the glider he provided a pair of struts similar to the arm rests of crutches. Lilienthal would run down a hill into the wind with his glider. When sufficient speed had been attained, the glider and Lilienthal would rise triumphantly into the air. He learned to travel fair distances and was fired with the ambition to put an engine on his glider. He did design a 2½-horsepower engine, weighing ninety pounds and mounted on a biplane. Before trying his new machine, Lilienthal decided to make a short flight in his old glider. Somehow the glider stalled, one wing dropped off, and the whole thing fell to the ground, carrying Lilienthal to his death. His powered machine was never tried. Other men, however, believed that Lilienthal had been correct in his idea of flying, and his death did not stop their experiments. About this time in America, a young man, just out of college, built a glider patterned after a sea gull. This young man was a Californian, John J. Montgomery. He worked alone and was so timid that he tried out his glider from a near-by hill at three o’clock in the morning. He was afraid that onlookers would laugh at him if his glider failed. It did not fail. He made a flight of six hundred feet--the first of many successful flights. Montgomery solved many of the problems of flight with little or no funds or encouragement. Because he worked alone and was until recently almost unknown, few written records of his work are available. All through the nineteenth century men continued their experiments in order to bring to a reality the dream of human flight. With each generation, they moved ever closer to the fringe of the secret but never quite grasped it.
