      This modified version of the Wright "B" Flyer, was the 
      first model produced in quantity by the Wright Brothers. It is 
      representative of Signal Corps Aeroplanes No. 3 and No. 4, purchased by 
      the Army in 1911 and used for training pilots and in aerial experiments. 
      At College Park, Md., in Oct. 1911, a Wright "B" was used for the first 
      military trials of a bombsight and bomb-dropping device. 
      The major modifications of this airplane are the 
      installation of an eight-cylinder Rausenberger engine in place of the 
      orginal four-cylinder Wright engine and the addition of ailerons on the 
      trailing edges of the wings in place of the Wright's lever control system.
      
      This airplane was used for flight instruction 
      by Mr. Howard Rinehart at Mineola, N.Y., in 1916. It appears here almost 
      exactly as it did when it was last flown by Lt. John A. Macready during 
      the International Air Races at Dayton, OH., in Oct. 1924.
