The ideal arrangement in mind at the end of the year was to train each pilot completely on this side of the ocean, where facilities are very good, supplies in abundance, and information and experienced pilots from the front available in ever-increasing numbers. The flyers can then be organized into provisional squadrons and wings and given training as large units with their own administrative officers and enlisted personnel so that they will be able to go immediately to the front, after a month or so of transformation work in France, learning geography and familiarizing themselves with new types of planes. Plans are under way looking to the establishment of such wings and brigades in the United States with the end in view of furnishing complete and fully trained units to the American Expeditionary Force. The whole training program was considerably held up by lack of equipment. Obviously it required far less time to select men for training than to build the fields, planes, and accessories necessary to train them. Primary training planes, the only type manufactured here before the war, soon became available in increasing numbers, till by the end of the year more were on hand than needed. The advanced training planes, however, presented problems wholly new to this country, so that primary planes had to be fitted with more powerful engines and equipment and made to serve the purpose. The first 16 single-seater pursuit planes were not delivered till January, 1918, the first bombers till March, and the first gunnery late in May. During this fiscal year a grand total of 407,999 hours were flown by Army aviators in the United States, as contrasted with 745.5 hours in 1914 and 1,269 in 1915. In the single week ending June 30, 1918, a total of 19,560 hours were flown, or 15 times, for that single week, the number of the whole year three years before. This, at 75 miles an hour, is equivalent to over 30,000,000 miles, or 1,223 times around the Equator. During it there were 152 fatalities, or 2,684 flying hours and 201,000 miles flown to each death. Of these, 86 were caused by stalls, when the plane, usually through some error by the pilot, lost its flying speed and dropped into a straight nose dive or turned into a tail spin, from which the pilot did not have the time or the skill to extricate it. Collisions were responsible for 30 other accidents, often due to failure to fly according to the rules. Side-slips, the only other large cause of accidents, resulted in 10 deaths. Regrettable as these accidents are, it is felt that, considering the newness of the science, the early state of development of the planes, the inexperience in instruction, and the necessity of teaching stunts in themselves rather dangerous, this number is not large. As a matter of actual statistics, fatalities in American training are less than half as large as those of the other allied countries.
