Although it is still a crude machine—in view of the perfected apparatus which is the aim of thoughtful designers—the aeroplane has demonstrated, in a conclusive way, its value as an instrument of war. In peace manoeuvres in France and Germany, and under actual war conditions in Tripoli, scouting machines have proved their ability to pierce most effectually what is known as "the fog of war." Air-scouts have, indeed, revealed the dispositions of an enemy so precisely as to make it necessary to alter—at a moment's notice—an entire plan of campaign. Ceasing to be fair-weather craft, powerful, modern-type aeroplanes can combat high and gusty winds, and are already capable of being used, for reconnoitring flights, on at least 80 per cent of the days of the year. No longer unreliable, they have become practical weapons. A squadron of war aeroplanes, carrying pilots and observers, can, as has been shown again and again, lay bare the disposition of a widespread battle-front. In one hour, they can perform the reconnoitring work which has hitherto been carried out in a day, and in a necessarily hit-or-miss fashion, by cavalry and other scouts. The use of well-trained corps of military airmen will revolutionise the tactics of war. No longer will two Commanders-in-Chief grope in the dark. They will sit, so to speak, on either side of a chess-board, which will represent the battlefield. Each will watch the other's moves; nothing will be concealed. From a blundering, scrambling moving about of masses of men, modern warfare will become—through the advent of the aeroplane—an intellectual process. The Commander-in-Chief who has no proper air-corps, in the next great war, will be in a hopeless position. He will have lost a battle practically before it begins. Whereas his opponent will know exactly what he is doing, he will be able to obtain nothing but vague and confusing tidings as to the movements of the enemy. Imagine two armed men approaching each other, one being blindfolded. The Commander-in-Chief without aeroplanes will be like a blindfolded man. One nation stands head-and-shoulders above all others in the matter of her aerial equipment and experience. That nation is France. So far ahead is she that it will be a long time before other countries will be able to come up with her; but Germany is now making desperate efforts to do so. Until recently, it must be said, England lagged inactively not only behind France and Germany, in the organising of an air-corps, but even behind such countries as Austria, Italy, and Spain. Now, however, there are promises of a change. For this, mainly, we must thank the energy and enthusiasm of Colonel Seely, Parliamentary Under Secretary of State for War. When these lines are being read, British aeroplane manufacturers will be preparing for an important military trial of aeroplanes, which is to be held in England during the summer. The War Office has begun to buy aeroplanes, although on a small scale. We now have a Royal Flying Corps; a body of skilled airmen is being trained. But money is spent very sparingly. Our equipment, compared with that of France, is still a negligible quantity. In machines, and men, and, above all, in training, we are very far behind. Only by persistent and intelligently directed work, by the spending of more money, by the practical encouragement of manufacturers, and by the appointing of executive officers who are experts in their field of work, can we hope even to approach the organisation of the air-corps of France. But a beginning has certainly been made. By the end of the forthcoming flying season, we should have in England a small, but well-equipped air service. And the work of this corps will be its own advertisement. Once the potentialities of the war aeroplane are realised adequately, a stinting policy will be impossible. It is our aim, in this book, to show what the war aeroplane has done, and can do. At present, its work has been confined to scouting. But it has other, and grimmer possibilities. It can, and without doubt will, be used as an engine of destruction—not by means of the bomb-dropping attacks of a few aeroplanes, but by the organised onslaught of large squadrons of weight-lifting machines, which will be able to rain down tons of missiles over any given spot. And there is another possibility, also. Machines are carrying heavier loads every day. Soon the practicability of aeroplanes to transport troops—particularly in regard to hurrying up reinforcements in an emergency—will be demonstrated. When two opposing armies both have large fleets of war aeroplanes, and these machines take the air in squadrons, prior to a battle, what will happen when they come in contact with each other? The question is one which the greatest military experts are discussing. Obviously, there will be an aerial battle, each aeroplane corps seeking to cripple the other. Each Commander-in-Chief will in fact desire, above all else, to obtain supremacy of the air. If he can do so, it will have the effect of seriously handicapping his opponent. Thus—probably waged with light guns firing explosive shells—the next great war will begin, not on earth, but several thousand feet in the air. Claude Grahame-White. Harry Harper. London, 1912.

- THE NIEUPORT MONOPLANE. Photo, M. Branger. This exceedingly interesting machine, which won the great French Military Trials, is generally admitted to be one of the most efficient flying machines in existence. A similar machine can be seen at work in Hendon, where it is piloted by Mr. Grahame-White.
- BRITISH-BUILT SCOUTING MONOPLANE. This aircraft, an exceedingly fast, single-seated machine, represents the type of machine now favoured by French authorities for urgent, rapid, general reconnaissance. Its constructors are Messrs. Short Brothers.
- READY FOR A SCOUTING FLIGHT. Here a latest-type reconnoitring monoplane, with its observer in the front seat and the pilot behind him, is seen just about to start upon an aerial voyage. The machine is a British-built Bristol, such as will be used in the forthcoming military trials.
- TWO-SEATED, BRITISH-BUILT WAR MACHINE. The Blackburn military-type monoplane, with accomodation for pilot and observer, has already made many successful flights; and it is expected to perform meritoriously in the War Office trials. In some respects it resembles the graceful Antoinette.
- THE ENGINE-IN-FRONT BIPLANE. With the above machine—a type increasingly used for Service work—the Naval officers now experimenting at Eastchurch, Isle of Sheppy, have been carrying out recent tests. It was designed, and built, by Messrs. Short Brothers, who are now constructing special aeroplanes for Naval use.
- MILITARY BIPLANE WITH TWO ENGINES. This exceedingly interesting machine, which possesses especial significance from the military point of view, is equipped with two Gnome motors. One drives two propellers placed in front of the main-planes, and the other actuates a single rear propeller. Normally, both engines run at easy speed; but, should one fail in flight, the other, by being accelerated, will maintain the machine in the air. Its designers and builders are Messrs. Short Brothers.
- BUILDING WAR AEROPLANES. In this picture—taken in the Bristol works—skilled artizans are seen busy with the building of the bodies of a consignment of military-type monoplanes. Although apparently frail, these frameworks are—owing to their method of construction—immensely strong.
- WEIGHT-CARRYING WAR BIPLANE. By Fitting "extensions" to the upper main-plane of the machine, as seen above, it is possible to achieve sustained flight with two, or even three occupants—or, should necessity arise, with a pilot and an appreciable load of explosives! The actual machine photographed is a Bristol, flying over the Brooklands aerodrome.
- WAR MONOPLANES "VOL PLANE." In the above picture, a two-seated, military type Bristol monoplane is seen descending, with engine stopped and propeller motionless, from a reconnoitring flight. Pilot and passenger are plainly discernable.
- MAPS FOR MILITARY AIRMEN. Photo, M. Roe. The French authorities are busy with the preparation of a complete set of "air maps" for the use of the military pilots, when flying from point to point. A section of one of these maps—which are coloured—is illustrated above.
- THE PILOT'S SEAT. Photo, M. Branger. In the illustration above is seen the driving seat of a military-type BlÉriot monoplane, with the airman's map, in its case, fixed immediately before him.
- PILOT AND "OBSERVER." Photo, M. Roe. The above photograph shows a military-type Breguet biplane, as used in the French manoeuvres, with pilot and observer in their places.
- MILITARY AIRMAN'S REPORT. Photo, M. Branger. After descending from a reconnoitring flight on a BlÉriot monoplane, in the French manoeuvres, the pilot seen above is imparting details of what he has observed to another officer.
- TRANSPORT OF WAR AEROPLANES Photo, M. Roe. In the manner depicted above—and also by means of motor lorries—were military aeroplanes transported from point to point during the French manoeuvres.
- MOTOR TRANSPORT. Photo, M. Branger. This picture shows how a Breguet military biplane, with its main-planes folded by the sides of its body, can be towed from point to point behind a motor-lorry.
- TRAVELLING WORKSHOP. Photo, M. Branger. In the French manoeuvres, a completely-equipped aeroplane repair shop, in the form of a motor-wagon, followed the military airmen as they moved from point to point. One of these invaluable "ateliers" is pictured above.
