FLIGHT JANUARY IITH, 1945 Four-seater design, proposed by Dohner and Lippincott from specifications prepared by author. A Survey of the Stage of Development Reached by the United States : Possibilities of the Class Hi£L10©!PTERS are at present in transition from theexperimental to the practical. To-day they are insight of their goal, for some of those now flying are truly practical in that they perform functions reli- ably and efficiently which can be accomplished by 110 other vehicle. Their development has made giant forward strides under the impetus of wartime necessity, and commercial appli- cations will begin as soon as the war is ended. The opera- tional experience accruing to helicopters of the military and naval forces of the United States and other Allied natio»^" also contributes to the development of a, safe, reasonably economical, small-family-sized helicopter within reach of middle-class incomes. However, the dedication of all industry and constructive effort to winning the war has left little time or money and few facilities for direct experi- mentation to develop personal helicopters. Despite all deterrents there are a number of far-sighted companies with great faith in the future of the family helicopter and with the courage and the means to persevere in bringing about that future. Among the hope- FROM time to time we have kept our readers informed of helicopter development at home and abroad. In the present article our American contributor surveys the U.S. field and draws attention to certain tasks already accom- plished and others for which this class of aircraft is especially suitable. He points out, as we have previously done, that the helicopter is not as yet the aircraft for everyone, but that it is at present in the transition stage between the purely experimental and the really practical. The sketches of the Bell helicopter were prepared by the author and are published here by arrangement with our New York contemporary Aero Digest.
