Airspace

“ The darkness hangs about the driving air-craft like a pall. The aviator anxiously scans the earth below him for an occasional light or the glare that a distant city casts on the sky. It is by those means alone that he can get his bearings, unless he is a skilled navigator and steers by the compass. ”

“ Just as the navigator must know the sea, so the aviator must have a knowledge of the heavens and the basic principles of aerodynamics in order to become a successful pilot. Although the air is volatile like the water, the aviator flies through it as a fish moves through water. Therefore the aerial navigator must know enough about the medium through which he travels to know what to do in an emergency. ”

“ A full four miles above the earth, and more than that beneath the level of our own onrushing ships, hung this great line of restless beams, and we knew it, at once, for the great line of air-forts that guarded the western approaches of the European Federation. For the beams we saw were the great beams of the air-forts' mighty searchlights, and those swinging shafts of radiance were of such intense brilliance and magnitude that even at our greatest flying height we could not hope to pass over them undetected. ”

“ I always think there is an heroic atmosphere about the flying-grounds at the front. It is the privilege of these green fields and gorse-grown heaths, with their fringe of sheds, to witness the finish of these epic adventures in the air. Out of the crystal clearness of the summer evening, from the drifting cloud-wrack of a stormy day, the aeroplanes drone home, laden with their cargoes of glorious deeds. ”

“ There is magic in salt water which transmogrifies all things it touches. The aeroplane with its cubist outline undergoes a sea change on reaching the coast and becomes a flying-boat, a thing of beauty, a Viking dragon ship, a shape born of the sea and air with pleasant and easy lines, and in the sun, the dull war-paint stripped from the natural mahogany, a flashing golden craft of enchantment. ”

“ The air is an ocean that gives uninterrupted access to every corner of the land and every reach of the sea. The air force is charged with responsibility for keeping the airlanes open to aerial commerce and should be provided with the ground or sea transport necessary to that job, but by the same token the ground and sea forces must develop and control all the instruments they require to perform their functions. And aside from the sound basis for this concept that lies in logic, the record is clear that it is equally sound in practice. ”

“ An airman, flying in a wind, is rather in the position of a man who puts to sea in a small boat when waves are high. Once he can clear the shore, the boatman feels at ease; but should a breaker catch him before he reaches the smooth, rolling billows a little distance from the beach, his craft may be overturned and dashed to pieces. So with the airman; his moments of peril, when flying in a gusty wind, come just as he is soaring from the ground, and when descending from a flight. Then an air-wave, like a sea-wave, may lift his craft and drive it with a crash to earth. ”

“ We are about to consider man’s efforts to rise from the bottom of this ocean and wing his flight a little way through the atmosphere above him. His excursions upward are limited, for he could not live near the surface heights of this ocean, vast and deep and boundless. The art and science of his flight through the air, because of its relation to the flight of birds, we call aviation. ”

“ Let there be a strong odor of burnt castor oil and gasoline as you enter the door; a wide view from the verandas of earth and sky; maps on the walls; and on the roof a canvas “pantaloon-leg” to catch the wind. Nothing else matters very much. There they will be as happy as any old airman can expect to be, arguing about the winds and disputing one another's judgment about the height of the clouds. ”

“ The performance of air transport in the war revealed that the air is like an ocean that affords uninterrupted access to any spot on land or sea. Experience proves that the airplane, contrary to widespread belief, is inherently an economical vehicle. ”

“ The aeroplane is such an essential part of the Intelligence in modern war that no detailed survey of the methods by which the Royal Flying Corps fulfils its functions as the eyes of the army can safely be given until the war is over. I have had to content myself, therefore, with seeking to impart to you at home some of the admiration with which the gallantry and endurance of our airmen in the field have inspired me, who have been privileged to see them at their work. ”

“ And passing constantly along these routes will be a volume of air-borne traffic—neat, privately owned planes; large and speedy passenger machines; multi-winged craft for the transport of goods; and here and there, flying swiftly and high, some slim-built war machine. Upon the land in the day-time, to indicate the direction of the airways, will be signs which may be read from high aloft; while at night, from signal towers, will flash forth lights, differing in the frequency and the colour of the beams they throw skyward, to guide the airman on his path. ”

“ It is five o'clock of a fine calm morning, when the Aeroplane is wheeled out of its shed on to the greensward of the Military Aerodrome. There is every promise of a good flying day, and, although the sun has not yet risen, it is light enough to discern the motionless layer of fleecy clouds some five thousand feet high, and far, far above that a few filmy mottled streaks of vapour. ”

“ Regular air service, in either the Navy or Army, is reckoned more exacting than ordinary flying, and for the reason that—say when upon manœuvres or special tests—the pilot of war-craft may have to make long flights in treacherous, blustering winds. ”

“ On a clear night, however, with flambeaux, search-light flares, etc., a pilot has little trouble in landing, for [152] the straightaway can be as illuminated as it is in broad daylight. Nevertheless, when the aircraft is high in the sky, owing to the vast distances of infinite space, the speed at which an aeroplane moves, and the drift out of its regular course, due to the wind, it is often difficult for the flier to keep his bearings. ”

“ For an aircraft is completely immersed in the air, so that besides its movement in relation to the air caused by its own mechanism, it moves with the air over the surface of the earth, the speed and path of the machine being the result of the two movements. ”

“ For the wind is now no longer an obstacle to flight, and as I have already noted at the beginning of this chapter, this is one of the most noticeable advancements in aviation, one that can readily be seen, understood, and appreciated even by the uninitiated. ”

“ The earth below seems to fade into insignificance; far-distant, skirting the brink of the cliffs like a thin, white ribbon, you see a lonely road; and all the time, climbing higher and higher through the sunshine, your pilot forces his plane aloft Three thousand feet, four thousand feet—still you ascend ”

“ They were ultimately composed by the union of the military and naval air forces under a single control, and the emergence of a new air force.
Wars have for many centuries been conducted on land and on sea. A third and larger theatre has now been found for them. The air flows over both land and sea; more than either land or sea it is the place of vision, and of speed and freedom of movement. What we of this generation are witnessing is a process whereby the air shall come into its own. ”

“ Within a comparatively short time, then, we ought to see many companies organized in this country for aerial transnavigation of the globe by helium airship! Before the year 1919 has come to a close we ought to see aeroplanes and dirigibles jumping the Atlantic from shore to shore. Who knows, it may even come to pass that man shall become as much a creature of the air as the birds! As a world of exploration and travel the heavens offer him many adventures. ”

“ Experience, the researches of science, and the growing skill with which aircraft are built, stand between the airman and many of his previous dangers. The aeroplane to-day, one of the structural triumphs of the world in its lightness and its strength, has a factor of safety which is sufficient to meet, and to withstand, not merely ordinary strains, but any such abnormal stresses as it may encounter—and which may be many times greater than the strains of normal flight. ”

“ This was not mere rhetoric, as the world will shortly realize. The science of aeronautics has already advanced so far that one is as safe to-day in the air as on the railway, on the sea or in a motor-car on the road. ”

“ For light loads, great speed, and quick manœuvering, the airplane is supreme. For heavy loads, long distance, ability to remain in the air for great periods of time, the dirigible is the only air craft that can fulfill the requirements. ”

“ Imagine that a battle impends, and that the Commander-in-Chief of one army seeks news as to the movements of some division of his enemy; so he orders the air-scouts to ascend. But the wind may be blowing hard; and if it is, and the aeroplanes are only fair-weather machines, they will have to remain on the ground till the wind drops, and perhaps miss their greatest chance during a whole campaign. ”

“ So aviation has two immense tasks ahead of it, instead of one. Not only must it create, by years of patient and determined effort, a flying service which will command the air, but craft must be designed and built also for the mail, goods, and passenger-carrying services, and to meet the needs of the aerial tourist. ”

“ What was the reason?
Because of an almost unbelievable, impossible happening.
The airplane had suddenly stopped its whirling evolutions, and was soaring majestically through the air not a hundred feet above their heads. ”

“ Notwithstanding all difficulties, the fact remains that, once they are overcome, the air is the ideal highway for travel and transportation. On the sea, a ship may sail to right or left on one plane only. In the air, we may steer not only to right or left, but above and below, and obliquely in innumerable planes. ”

“ Ships are limited to one element, the water, which has very definite boundaries. Aircraft, too, are limited to one element, the air; but this element has no boundaries so far as the earth is concerned, and aircraft will be navigable to any and every part of the globe. ”

“ Although prevented from any great expansion in the years following World War I, the Army led the way in many phases of aviation. United States Army planes were the first to fly around the world. Army aviation also pioneered night flying and the use of the lighted airfield, refueling in the air, and radio communication between ground and plane. ”

“ Airplanes laden with scientific instruments whirred overhead, exploring the outskirts of the speeding shadow, tiny spots that grew dimmer as the moon continued her encroachment on the sun's blazing rim. ”

“ The Control Cables of twisted wire, a bit tight before, have slightly lengthened by perhaps the eighth of an inch, and, the Controls instantly responding to the delicate touch of the Pilot, the Aeroplane, at the will of its Master, darts this way and that way, dives, loops, spirals, and at last, in one long, magnificent glide, lands gently in front of its shed. ”

“ In the air, our road bed is perfect. Here a rut may pitch the whole machine over the fence. High up in the air you have no objects along your path to measure flight. The ground is so far away that it is no criterion. ”

“ The foregoing outline of the development of aviation from the earliest times up to the war—a story of human endeavour and achievement in the air with its attendant dangers and difficulties—is not without value in endeavouring to assess that which has since occurred. ”

“ In sections where airplanes had never come or at most had been merely glimpsed—a swift moving speck in the sky that came out of nowhere and disappeared into nowhere—a plane that really came down to earth was a novelty. ”

“ The narrative of the first aerial voyage, written by one of the two first aeronauts, exists, and we are in a position to place it before our readers. Such an enterprise certainly demanded great courage in him who was the first to dare to confide himself to the unknown currents of the atmosphere It threatened him with dangers, perhaps with death by a fill, by fire, by cold, or by straying into the mysterious cloud-land. ”

“ Nerve and rapidity of thought save the aviator in many a ticklish position. It is perhaps a tribute to the growing perfection of the airplanes that in certain moments of peril the machine is best left wholly to itself. ”

“ Before the airman leaves Earth he sets his compass to the course to be steered, and during the flight he has only to see that the two boldly-marked north points—on the dial and on the outer ring—coincide to know that he is keeping his course. ”

“ SLOW RISING NEARLY CAUSED DISASTER AT THE START OF THE GREAT FLIGHT
The receiving equipment on aëroplanes and airships is arranged so as to indicate, with a comparatively high degree of accuracy, the direction from which wireless signals are received. The position of the sending, or beacon, station being known, the bearing of the aircraft from that station may be plotted on a suitable chart, in which small segments of great circles are represented by straight lines. ”
