Wright 1909 Military Flyer
Upon being purchased by the Signal Corps for $30,000 on August 2, 1909, the original airplane was redesignated Signal Corps Airplane No. 1, the world's first military heavier-than-air flying machine. It was used in October 1909 for giving flight instructions to Lts. Frank P. Lahm and Frederic E. Humphreys, and in 1910 it was used by Lt. Benjamin D. Foulois to teach himself how to fly. By March 1911, the airplane was no longer fit for use and was retired. It is now on exhibit at the Smithsonian Institution, Washington D.C. (courtesy photo)
