Draft (air)

“ In aerial war the stronger side, even supposing it destroyed the main battle fleet of the weaker, had then either to patrol and watch or destroy every possible point at which he might produce another and perhaps a novel and more deadly form of flyer. It meant darkening his air with airships. It meant building them by the thousand and making aeronauts by the hundred thousand. A small uninitated airship could be hidden in a railway shed, in a village street, in a wood; a flying machine is even less conspicuous. ”

“ To mount in a balloon that one has not constructed, and which [222] one is not in a state to guide, constitutes the easiest of performances. A little cat has done it at the Folies-Bergère."
Now in war service overland the air-ship will, doubtless, have often to mount to considerable heights to avoid the rifle fire of the enemy, but, as the maritime auxiliary described by the expert of the French Navy, its scouting rôle will for the most part be performed at the end of its guide rope, comparatively close to the waves, and yet high enough to take in a wide view. ”

“ Any gun we can hope to employ against aircraft with some degree of success must fulfil special conditions, for it has to deal with a difficult and elusive foe. Both the lighter-than-air and the heavier than-air craft possess distinctive features and varying degrees of mobility. Taking the first-named, the facility with which it can vary its altitude is a disconcerting factor, and is perplexing to the most skilful gunner, inasmuch as he is called upon to judge and change the range suddenly. ”

“ Our pilots have had to learn by their own experience in the air—and a gallant and bravely bought experience it has been—the fighting tactics of the aeroplane. They have had to learn to distinguish “by silhouette” the different types of German machine, and to discover the most efficacious way of dealing with each one, according as the position of the propeller and of the driving-seat in relation to the planes restricts the field of fire of the enemy machine-gun. ”

“ Our aviator swings free in a great circle, banks, and at top speed makes back to his air-line patrol, while the German Archies open up on him with redoubled violence, as, serenely confident, he hums along his way.
It is truly wonderful what a fire an aeroplane can pass through quite unscathed as far as actual hinderance to flight is concerned. Many a time you can count nearly two hundred wreathing balls of smoke in the track of [43] the machine, and yet it sails placidly onward as though the air were the native element of its pilot and the attentions of Archie nonexistent. ”

“ To accomplish these results the aeroplane must fly at a sufficient elevation to render difficult the hitting of a vital part of the machine or the aviator by hostile rifle or artillery fire. While the modern rifle in use in our army will fire a ball about three thousand five hundred yards straight in the air, it is generally accepted among aviators that an aeroplane would be practically safe, save from a chance shot, at three thousand five hundred feet. ”

“ A gun firing a twenty-pound shrapnel shell is not pointed on an object with the celerity with which a practised revolver shot can throw his weapon into position. The gunner on the ground seeing an airplane flying five thousand feet above him—almost a mile up in the air—hurries to get his piece into position for a shot. But while he is aiming the flyer, if a high-speed machine, will be changing its position at a rate of perhaps 120 miles an hour. ”

“ A whirr that sounded loud and insistent above the dull roar of the heavy guns, a sudden movement that quickly increased in velocity until the plane was bounding like a rabbit over the open ground, then an upward slant, a beautiful curve that left the ground behind, and another air pilot was off for the post of duty. ”

“ Two new types of aeroplane have been alluded to in the last, preceding paragraph; the fast-flying, quick-climbing racer and the slow-going, heavy-weight carrier. We are of opinion that there should be three types in all for military purposes. Of greatest importance and in greatest numbers we should have the middle-class machines; those capable of staying in the air for at least three hours of continuous flight, while carrying two men and one hundred and fifty pounds extra, of either wireless apparatus or machine gun and ammunition. ”

“ 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. ”

“ In the later formations single-seater fighters flew above the bombers for the purpose of driving off hostile craft. Formation flying was not fully developed when the end of the War brought stagnation in place of the rapid advance in the strategy and tactics of military air work. ”

“ In a recent article the editor of The Aeroplane referred to the erstwhile terror of the air as follows: "The best of air-ships is at the mercy of a second-rate aeroplane". Enough to make Count Zeppelin turn in his grave!
To-day in aerial warfare the air-ship is relegated to the task of observer. As the "Blimp", the kite-balloon, the coast patrol, it scouts and takes copious notes; but it leaves the fighting to a tiny, heavier-than-air machine armed with a Lewis gun, and destructive attacks to those big bomb-droppers, the British Handley Page, the German Gotha, the Italian Morane tri-plane. ”

“ You see, Jerry, the big outstanding feature of the war across the water has been the work done by two recent inventions, the submarine and the aeroplane. That set me thinking. The water isn't deep enough around here to do much experimenting with submarines, but there's dead oodles of air. So aeroplanes it had to be. Now, the aircraft have been a distinct disappointment, except as scouting helps, because the high speed of the aeroplanes makes accurate bomb-dropping almost impossible. ”

“ Employment of Aircraft in Large Bodies. Air Tactics. In some of the previous Chapters (Chapter VII., et seq.) the question of aircraft fighting—i.e., aeroplane versus aeroplane—has been considered, and matters such as armament have been fully discussed. We shall now deal with the employment of the armed machine in its fighting capacity, not as a single unit, but as part of a force whose function is the destruction of the armed air fleet of the enemy, and the crippling of his reconnaissance service. ”

“ But scouting airplanes, such as those were, do not go in for bomb dropping. There are three sorts of airplanes. First come the scouting planes—fairly fast, good climbers, able to stay in the air a long time. Their business is just to spy out the lay of the land over the enemy's trenches—not to fight or drop bombs. ”

“ Thus we find that in aviation man has designed the propeller, which, by its rapid revolutions derived from the motive power of the aerial engine, cuts a spiral pathway through the air and drives the light craft rapidly forward. The chief use of the planes is for support to the machine, and the chief duty of the pilot is to balance and steer the craft by the manipulation of the rudder, elevation and warping controls. ”

“ A spirited contest in the air is one of the grimmest and most thrilling spectacles possible to conceive, and it displays the skill of the aviator in a striking manner. Daring sweeps, startling wheels, breathless vol-planes, and remarkable climbs are carried out. One wonders how the machine can possibly withstand the racking strains to which it is subjected. The average aeroplane demands space in which to describe a turn, and the wheel has to be manipulated carefully and dexterously, an operation requiring considerable judgment on the part of the helmsman. ”

“ In particular, I have expressed astonishment at hearing of experimenters rising to these altitudes without adequate purpose in their early stages of experience with dirigible balloons. All this is very different, however, from a reasoned, cautious mounting, whose necessity has been foreseen and prepared for.
To keep out of rifle range the air-ship will but seldom be obliged to make these tremendous vertical leaps. Its navigator, even at a moderate altitude, will enjoy a very extended view of the surrounding country. Thus he will be able to perceive danger afar off, and take his precautions. ”

“ The air craft hovered above our heads, but we were forbidden to fire at it, the extremely difficult, almost vertical aim promising little success, aside from the danger of our bullets falling back among us. Our reserves in the rear had apparently sighted the air craft too, for soon we heard a volley of rifle fire from that direction and simultaneously the aeroplane arose and disappeared in the clouds. ”

“ The value of a correct initiative and the aeroplane's rôle as an offensive weapon were fully appreciated and brought out in the Training Manual of the Royal Flying Corps which we compiled at Farnborough, and which was published early in 1914 by the War Office. It says:—
"It is probable that one phase of the struggle for the command of the air will resolve itself into a series of combats between individual aeroplanes, or pairs of aeroplanes. ”

“ All authorities may to-day be said to agree on the broad fact of the utility and importance of the flying-machine or aeroplane—or, more broadly, aircraft—in warfare; but at present the air service as a fourth Arm of the military organisation, either of this country or of any of the other great military Powers, can only be regarded as of a tentative and experimental character. It is, unfortunately, not yet possible to draw conclusions of a lasting nature from the actual usage of aircraft in the present war, mainly for two reasons. ”

“ All of these things must be connected to the controls in the hands of the pilot. The front [Pg 244] edges of the wings are raised above the line of flight; and when the propeller driven by the engine forces the wings through the air, the airplane is lifted and flies.
All of the airplanes built for the United States during the war were tractor biplanes. In a plane of the tractor type the propeller is in front and pulls the machine. The biplane is so called because it has two planes or wings, one above the other. ”

“ None of the designers of airships and aeroplanes had known clearly what their inventions might have to fight; many had not imagined they would have to fight anything whatever in the air; and had planned them only for the dropping of explosives. ”

“ One or other may be forced to yield and fly, scattering in confusion; and after this there may be the aerial battle proper, in which the large, heavily-armed craft, and the giant airships with their batteries of guns, will come into action. The aeroplane, in fighting an airship, will have the advantage that it offers a smaller mark, and one also which is moving rapidly through the air. It may also be struck many times before it is crippled or put out of action. Shot passing through its planes will make little difference to it; and the occupants will sit in a hull which is armoured. ”

“ According to this plan, although both names stand for an aerial vessel88 capable of travelling in the sky by its own motion, an airship is a machine supported in the air by reason of its buoyancy, while a flying machine is kept aloft only by virtue of its onward movement.
In other words, part of the construction of an airship consists of a bag or balloon, filled with gas or hot air, which causes the whole to rise and maintain its position in the air. ”

“ What happens when two aeroplanes meet in dire combat in mid-air and one is vanquished? Does the unfortunate vessel drop to earth like a stone, or does it descend steadily and reach the ground uninjured? ”

“ Sweeping once more upwards, the airman regains the pre-determined level, performs a certain evolution in the air which warns the observer at his base that he has made a discovery, and promptly drops his guiding signal directly over the point from which he has drawn fire. ”

“ So far as the British lines are concerned the men in the trenches keep a sharp look-out for hostile aeroplanes. The moment one is observed to be advancing, all the men seclude themselves and maintain their concealment. To do otherwise is to court a raking artillery outburst. The German aeroplane, detecting the tendency of the trenches describes in the air the location of the vulnerable spot and the precise disposition by flying immediately above the line. ”

“ In the air two observation planes flying over the Allied front were signaling to the German batteries in the rear, from which came the barrage protecting their infantry from Allied advances. At once they knew what to do.
Both drove on through the hostile fire and bore down upon these observation biplanes. Observation planes are not good fighters. In less than a minute after rising those two fighting planes had chased the larger, slower machines off the ground. ”

“ The aeroplane stood out, almost motionless as it seemed to me, over the German lines, while with a “pom-pom-pom!” the German anti-aircraft guns ringed it round in puffs of white smoke. Like the hawk that continued to hover over the valley, it was watching—watching. Like the hawk’s, its searching glance plunged down into the animate life far below, the life that pursues its normal round unperturbed because it knows it cannot escape from the eyes in the sky.
[Pg 320]
The aeroplanes are the eyes of the army. They alone have made possible the war of positions. ”

“ The arrangements made for handling airships on the ground and while landing, and also for moving them in the open, provide scope for great ingenuity. An airship when about to land is brought over the aerodrome and is "ballasted up" so that she becomes considerably lighter than the air which she displaces. ”
