We all knew that the balloon was the fore­father of the airplane. In 1766 Henry Cavendish, an English nobleman, proved that hydrogen gas was seven times lighter than air. From that discovery the balloon came into existence, and from the ordinary balloon the dirigible, a cigar-shaped airship, was evolved.

Study of aeronautics and laws of the aerial locomotion of birds and projectiles led to the belief that mechanism could be evolved by which heavier-than-air machines could be made to travel from place to place and remain in the air by the maintenance of great speed, which would overcome by propulsive force the ordinary law of gravitation. Professor Langley of Washington, who developed much of the theory which others afterward improved upon, was subjected to much derision when he sent a model airplane up, only to have it bury its nose in the muddy waters of
