[14] From Wright Hill, near Dayton, on which there is a memorial monument, one has a view of the great government aviation center of Wright and Patterson fields, the latter of which includes the Huffman tract. The monument bears the legend: “In Commemoration of the Courage, Perseverance and Achievements of Wilbur and Orville Wright. Through Original Research the Wright Brothers Acquired Scientific Knowledge and Developed Theories of Aerodynamics which with their Invention of Aileron Control Enabled Them in 1903 to Build and Fly at Kitty Hawk the First Power-Driven, Man-Carrying Aeroplane Capable of Flight. Their Further Development of the Aeroplane Gave it a Capacity for Service which Established Aviation as one of the Great Forward Steps in Human Progress. As Scientists Wilbur and Orville Wright Discovered the Secret of Flight. As Inventors, Builders and Flyers, they Brought Aviation to the World.” [15] Bishop Wright lived to be nearly 89. [16] The italics in all letters quoted in this chapter are supplied. [17] A still later plane, the one sold by the Wrights to the United States Government in 1909, was afterward given to the Smithsonian by the War Department, and it was placed on exhibition. It was wrongly labeled as the 1908 plane. [18] For an account of early Langley and Wright aeronautical investigations, see Smithsonian Report for 1900 and The Century Magazine of September 1908.
