[8] When the airplane was first considered for military purposes, the Wrights thought the plane could be such a destructive instrument in warfare that no nation, no government, would risk subjecting people to the terrors it could create. Another reason why the brothers thought the machine might prevent war was the possibility that it could be used against those persons chiefly responsible for bringing on a war. That is, if one nation started an attack against another, with or without a declaration of war, the nation attacked could drop bombs on, say, assembled members of the legislature, or the buildings housing the highest officials of the aggressor country. That possibility, it was hoped, would deter any nation from taking warlike steps. [9] Though there was no agreement in regard to the altitude at which the machine would fly, the Wrights were willing to guarantee 1,000 feet, and said that so far as the machine itself was concerned it could be flown at an altitude of a mile. One of the Germans remarked that half a mile from the ground should be enough, as no gun in existence would be likely to hit so swiftly moving a target at that height. [10] Afterward a major general. [11] The Wright monument on top of Kill Devil Hill, ordered by act of Congress and dedicated in November, 1932, is probably the most impressive memorial ever built anywhere in the world to do honor to anyone still living. Reaching sixty-one feet above Kill Devil Hill, with a powerful beacon light at its top, it may be seen for miles. About the four sides of the base reads a legend: In Commemoration of the Conquest of the Air by The Brothers Wilbur and Orville Wright, Conceived by Genius, Achieved by Dauntless Resolution and Unconquerable Faith. “Anchoring” the once shifting sands of Kill Devil Hill by ingenious planting of suitable grasses and shrubbery provides a memorial in itself, as is the national park of three hundred acres that includes the hill. [12] A Wright monument at Le Mans, by the sculptor, Paul Landowski, was dedicated in 1920. [13] A Wright monument at Pau was dedicated in 1931.
