Scope (from Introduction): "The revolutionary influence of aviation on military strategy is now recognized by laymen as well as by military authorities. It is also apparent that the influences of aviation on civilian life are equally revolutionary and perhaps more important from the long-term viewpoint. Wide seas, dangerous reefs, precipitous mountains, frozen wastes, and jungle depths, all barriers to earthbound generations, have become features of the landscape below the global sweep of the airplane travelers in the ocean of air which is now the third dimension for an air-free people. No aspect of human ecology will remain unaltered by this new instrumentality which not only abolishes distances but also reshapes basic human geography and remolds the internal and external relationships of national and continental population groups. City, state, national, and even continental boundaries vanish or become curious anachronisms to the stratospheric travelers on great-circle routes which wheel around a planet bereft of topographical restrictions.

Our educational leaders and the schools and colleges which they represent have made it clear that they will not only contribute directly to the paramount task of winning the war by helping to train the young men who will give air supremacy to the United Nations but will also help prepare the American people for constructive living as world citizens in the air age.The revolutionary influence of aviation on military strategy is now recognized by laymen as well as by military authorities.
