ALMOST exactly ten years ago (December, 1908) the undersigned had the honor of addressing, from this same platform, the American Society of Mechanical Engineers on the
subject of Military Aeronautics, at its annual meeting. The preceding summer months had witnessed the first public flights of the Wright airplane at Fort Myer, Virginia.
The Signal Corps of the United States Army, under date of December 23, 1907, had issued an advertisement and specification for a heavier-than-air flying machine, and the sealed proposals under this specification were opened formally at Washington at twelve o'clock noon on February 1, 1908. The main requirement before acceptance, by the Government, was an endurance test in which the flying machine must remain continuously in the air for one hour without landing.
