Ray A. Dunn, Army Air Corps, Sppointed as eonsultant to the fund by Harry F. Guggenheim, president. Capt. Dunn is the second Army officer appointed to the fund as a eonsultant. | the Lieut. James Doolittle, one of the Army’s foremost fivers, has been as- signed to the fund for nearly a year and is eondueting research work in blind fiying and methods of ecombatting the fog menace to air navigation. ‘Outstanding Problem. “Aviation insurance is one of the out- standing problems not only of the com- merel..l .vma but of all those engaged ™ juggenheim stated in g the nwoim.msnt -nu its approval by the War Department “At present, rates for mmnm of this kind are almost prohibitive and this is very largely dlll to lhl almost eomplete lack of correlated information on the subject. The attempts made by American insurance companies to solve this problem have been hampered by the inadequate scope of the mumu available. Situation Confused. ““The results of the studies made by insurance actuaries have all differed with respect to the hazards of different elasses of flylng‘ and these differences have resulted the varying and ex- tremely high premium rates established by the underwriting companies for avi- ation risks. In the face of this con- fused situation it has been difficult, if met impossible, for the public as well ag for military and naval of the Dnited States engaged in aviation to obtain the amount of insurance cover- age which has been desired. “Because of the importance of life in- surance to aviation. the fund has asked Capt. Dunn to conduct a survey which will eompile accurate and official data in regard to aviation mortality and in so doing make avallable to the insur- ance underwriters those statistics which are necessary for the satisfactory stabil- imation of this unsettied question.” Air l)gn Required.

Peace-time activities of the Army Alr Corps make it an instrument for the bullding up of all phases of commercial seronautics, Gen. Charles P. Summerall, chief of staff, said in & recent address on the activities of the various branches of the Army. “It was the Army 8ignal Corps,” Gen. Summerall said, “that first Dhmuud aviation and the Army Air first demonstrated the capal airplanes in the historic world.

In the years immedi- ately followin, ‘ the war the graduates of the Army flying schools were a tre- mendous factor in the development of commercial aviation. While no longer almost the exclusive source of our high- ly trained pilots, these schools cont! their contribution to the Nation's fiyers. “Nor is this all. The Air Corps borne the burden of engineering devel- opment and is in many respects a gi- gantic aeronautical laboratory. The spectacular flights that demand the ut- most from the aviator and from his machine, that telescope distance in terms of time, are not by any means stunts. They are rigorous tests of ma- terial and of man's ability to handle it. They are to aviation what a speedway is to the automotive industry. From the bombers and transport planes of the Air Corps have evolved the air freighters and passenger cnrrlen of commercial aviation. In the pursuit plane lies the germ of the sky sportster of tomorrow.” NEW BEACON AT WICHITA.
