True, years before, in fact, nearly a decade before, the Wright brothers had risen from the ground and flown about through the air in a machine which defied conventional rules and beliefs. The world had looked on in wonder, and then dropped back into an apathetic acceptance of the fact. Despite the actual demonstration and the field of imagination which was opened up, these early flights proved to be a world's wonder only for a moment.

For years aviation dragged on. Daredevils and adventurers took it up to make money by hair-raising exploits at various meets and exhibits. Many died, and the general public, after satiating its lust for the sensational, turned its thought elsewhere. Flight was regarded as somewhat the plaything of those who cared not for life, and as a result the serious, sober thought of the community did not enter into its solution.

Business men held aloof. Apart from circus performances there seemed no money to be made in aviation and consequently practically none was invested in it. What little manufacturing was done was by zealots and inventors. Workmanship was entirely by hand, slow, amateurish, and unreliable.

Strangely enough, scientists were equally apathetic. It might have been expected that their imaginations would be fired by the unexplored realms of the air and by the incomparably new field of experiment opened to them; but they were not. The great question, that of flight itself, had been answered, and but few were interested in working out the less spectacular applications of its principles. Aviation remained very much of a poor sister in the scientific world, held back by all the discredit attaching to the early stunt-flying and by failure to break through the ancient belief in its impracticability for any purposes other than the sensational.

So the science limped along, unsupported by either public interest or capital. Now and again some startling feat attracted the world's attention, as when the English Channel was first crossed by air and England was made to realize that her insularity was gone. For a moment this feat held public interest, but again without a true realization of its significance. There seemed nothing which would drive man to develop the gift which had been put within his reach.

Up to that fatal moment in August, 1914, when the World War broke out, aviation had made but little progress. All nations had what passed as air services, but they were very small and ill-equipped and were regarded with doubt and suspicion by the military leaders of the various countries. Compared with what has since taken place, the experiments previous to the war were only the most rudimentary beginnings.

Then came the war. Man's imagination was aroused to a feverish desire for the development of any device for causing destruction. Conventions, usages, and prejudices were laid aside and every possibility of inflicting damage on the enemy was examined on its merits. Sentiment or any regard for personal danger involved was thrown to the winds. Science was mobilized in all lines in the struggle to keep one step ahead of the enemy.

Almost immediately aviation challenged the attention of the responsible leaders. The handful of French planes which in those early fateful days of August penetrated up into Belgium brought back the information of the German mobilization there, and this led to the rearrangement of French forces in preparation for the battle of the Marne. As a result aviation at once leaped into high repute for scouting purposes and the foundations were laid for its great development.

But as aviation had proved itself in the warfare of movement leading down to the Marne and sweeping back later to the Aisne, so it proved itself in the French warfare which was so unexpectedly to follow. When the two opposing lines were so close together that they locked almost in a death grip, each side kept such strict watch that ground observation was greatly hampered. Apparently there was only one way to find out what was going on behind the enemy's lines. That was by looking from above. The first aviator, therefore, who sailed into the air and spied the enemy introduced one of the most important developments in the strategy of modern warfare.

Thereupon began one of those silent battles of the rear, of which we see and hear so little, but which indeed decides sometimes far in advance of the actual test of battle just which side is going to win. Scientists, inventors, manufacturers, and practical fliers began coming together in increasing numbers to exact from this latest method of warfare its last degree of usefulness. In the studies and factories on both sides of the lines men dedicated themselves to the solution of the problem of flight.
