DWIGHT D. EISENHOWER. THE WHITE HOUSE, JANUARY 28, 1957. in "Page missing from available version" Letter of Submittal NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS WASHINGTON, D. C., October 17,1956. DEAR MR. PRESIDENT: In compliance with the act of Congress approved March 3, 1915, as amended (U. S. C. title 50, sec. 151), I submit herewith the Forty- second Annual Report of the National Advisory Committee for Aeronautics for 1956. Aeronautics is progressing at a remarkable rate. Scientific prob- lems are multiplying in number, difficulty, and cost. Under military stimulation, development efforts are extending beyond our basic knowledge. Real progress can be accelerated, and on a more eco- nomical basis were scientific research accorded priority and conducted on an adequate basis in advance of development. There is a growing demand for more scientists and engineers. Long range measures are being taken to stimulate the education of larger numbers. In the meantime, the law of supply and demand is forcing salaries up. Government research organizations, operating under rates of compensation fixed by law, cannot recruit or retain adequate numbers of scientists and engineers. NACA is losing out- standing and irreplaceable leaders in aeronautical science. This weakening trend must be reversed. The simplest and the best remedy is the enactment of legislation authorizing the Government to pay the going rates for scientists and engineers. Leadership in aeronautical science and American supremacy in the air are at stake. The necessary legislation is strongly recommended. Respectfully submitted. JEROME C. HUNSAKER, Chairman. THE PRESIDENT, The White House, Washington, D. C. National Advisory Committee for Aeronautics Headquarters, 1512 H Street NW., Washington 25, D. C. Created by Act of Congress approved March 3, 1915, for the supervision and direction of the scientific study of the problems of flight (U. S. Code, title 50, sec. 151). Its membership was increased from 12 to 15 by act approved March 2, 1929, and to 17 by act approved May 25, 1948. The members are appointed by the President and serve as such without compensation.
