The book divides itself naturally into sections. First there is the story of the very early and haphazard tests, and of the notes and speculations of scientists; then of the advent of the practical, patient experimenter—the man who, taking a hint from the birds, realized that ere he could hope to fly he must learn first to balance himself when in the air. This stage, of course, introduces Otto Lilienthal—the German engineer who, by his gliding flights from hilltops with outstretched, bird-like wings, has won the honour of being styled “the father of the aeroplane.”
From a narration of his work, so vital a link in the chain of progress, the story passes to those two men—unflurried, reserved, and infinitely painstaking—who at last evolved order out of chaos: Wilbur and Orville Wright. Their diligent study is described; their perfected glider; the building of their own motor; and, finally, that great day of triumph which came in 1903—just eleven years ago.
The world being given thus an aeroplane which would fly, the steps which followed were mainly those of perfection and improvement. One by one the limitations were removed. At first men dared only to fly above a smooth-surfaced aerodrome, in case their motors should stop and send them gliding back to earth; but soon, gaining confidence in themselves and in their engines, they were passing high across country. So, also, in regard to their enemy the wind. Dreading even a gentle gust at first, for fear it might overturn them, they have gained so rapidly in skill that, thanks to their experience and the stability of their machines, the airmen of to-day will do battle with a gale. In this section of our book is a description of the greatest feats, both of early days and of modern times—such as speed flying, altitude records, and the touring of continents by air.
Thus logically may the tale be told: with digressions of course to cover the risks of aviation, and to explain how they are being overcome; to deal with aerial warfare and its many problems; to describe the advent of the sea-plane; and to discuss the day when—a perfected passenger craft being available—men will journey by air as they do now by land or sea.
