It is well known that accidents during flight are not always the result of faults in the machine or in the atmospheric conditions. Statements from all countries are to the effect that of the total number of fliers incapacitated for flying service during the war, about 8 per cent, were rendered unserviceable because of mechanical shortcomings of plane or engine; adding to this 2 per cent, incapacitated by the enemy, the remaining 90 per cent. represent trouble in the flier himself.

With the armistice, the urgent need for aviators ceased, and economy demanded that experimental work in problems of flying be cut to a minimum. But the concentrated work of the few years of warfare had borne fruit. It had interested many men of no physiologic training in problems of equilibrium. It had concentrated the attention of not a few able physiologists on the basic problems of balancing. The choosing
