From what has been said it will be seen that the factory continued, as it began, in close relations with the army. It had been founded, under army auspices, at an important inland military centre, and it was not so well adapted, by its history or situation, to serve the navy. The results obtained by research at the National Physical Laboratory, and by experiment at the factory, furthered the science of aviation, and were open to all. But when flight began, a united national air force was not thought of by any one, or was thought of only in dreams. Meantime the new invention offered to the navy, no less than to the army, new opportunities of increasing the power of its own weapon. The problems of the navy were not the problems of the army, and a certain self-protective jealousy made the two forces keep apart, so that each might develop unhampered by alien control. The navy trusted more to private firms, and less to the factory. It was a difference of tendency rather than a clean-cut difference of policy. Both army and navy made use of the results obtained at the laboratory and the factory. The army employed many private makers for the supply of machines and engines, and the navy, in the course of the war, ordered a very large number of that most famous of factory machines—the B.E. 2c. But the navy stood as far aloof from the factory as possible, and looked mainly to private firms not only for the supply of machines and engines, but for much of its experimental work. Several of the firms who devoted themselves to the needs of naval aviation did excellent service as pioneers. The most distinguished of these was the firm of the Short brothers—that is, of Messrs. Oswald, Eustace, and Horace Short. The impulse of their work was scientific, not commercial. As early as 1897 Mr. Eustace Short was an amateur balloonist, and his younger brother Oswald, at the age of fifteen, began to accompany him on his voyages. In a public library they came across that celebrated record of balloon voyages, Travels in the Air, by James Glaisher, and made up their minds to construct a balloon of their own. Success led them on step by step; in 1905 they contracted to supply captive war balloons for the Government of India, and in 1906 they became the club engineers of the newly formed Royal Aero Club. The reported successes of the Wright brothers in America shifted the interest of the club, and of the club engineers, from balloons to flying machines; in 1908 they built their first glider—a complete miniature Wright machine, without the power plant—for the Hon. C. S. Rolls. At about this time they were joined by the eldest of the three brothers, Mr. Horace Short, an accomplished man of science and a lover of adventure; from this time onward the firm of the Short brothers never looked back. From sketches made by Mr. Horace Short, they built six biplanes to the order of the Wrights. They constructed, in 1909, the aeroplane on which Mr. J. T. C. Moore-Brabazon won the prize offered by the Daily Mail for the first all-British machine which should fly a circular mile. They made the outer cover, gas-bags, valves, pressure-gauges, and controlling rudders for the first rigid airship constructed to the order of the Admiralty. Their early work was done at Shellness, the flying centre for members of the Royal Aero Club, but in 1909 they moved their sheds to Eastchurch in the Isle of Sheppey, which thereafter became the flying centre of the navy. It was here that the first four naval aviators were taught to fly. The tale of the successes of the various Short machines would make something not unlike a complete history of early naval aviation. The first landing on the water by an aeroplane fitted with airbags, the first flight from the deck of a ship, the first flight up the Thames, not to mention many other incidents in the progress of record-making, must all be credited to the Short factory. The brothers held that the right way to advance aviation was to strengthen the resources of the aeroplane-designing firms, so that they might carry out their ideas without being dependent on Government demands, and the extraordinary success of the Short designs for aeroplanes and seaplanes did much to promote that creed.

At the factory the work with airships was continued, though it languished somewhat as interest in aviation grew. England had shown the way in the use of gold-beater's skin, which is greatly superior in endurance and impermeability to any other fabric, but the knowledge leaked through to Germany, and when the price of the skin, always high, suddenly rose higher from heavy German buying, England fell back on rubbered cotton. The Baby, altered and enlarged, was rechristened the Beta, and a new ship, called the Gamma, made of rubbered fabric, was added in 1910. The Gamma, though twice reconstructed and altered, was never satisfactory. In 1912 Beta No. 2, built in streamline shape, about a hundred feet long, stiffened at the nose with ribs like umbrella-ribs, and driven by a forty-five horse-power Clerget engine, was more of a success. Other airships, the Delta and Epsilon, of increased size and engine-power, were designed between 1911 and 1913. In this latter year the Air Committee, a body appointed in 1912 by the Committee of Imperial Defence, advised that the navy, that is to say, the Naval Wing of the newly-formed Royal Flying Corps, should take over the development of all lighter-than-air craft. This advice, which was carried into effect by the end of the year, put an end to military experiments with airships, and supplied the navy with the nucleus of that airship force which during the war did so much good service, in convoy, in scouting for submarines, and in patrolling the coast and the English Channel.

The earliest experiments undertaken by the Admiralty with craft lighter than air had been ambitious and unfortunate. It was always recognized by those who gave thought to aeronautics that for naval purposes the airship has some advantages over the aeroplane. It can remain longer in the air, so that its range of action is greater; it can easily carry wireless apparatus both for transmitting and for receiving; it can take up a stationary point of vantage where the aeroplane must needs keep moving; it can lift a greater weight; and (not least important) it can enormously add to the efficiency of the observer by supplying him with comfortable and habitable quarters. These things did not escape the attention of the small and enthusiastic band of naval officers who from the first were believers in the air. Their ideas took shape in proposals which were submitted by the Director of Naval Ordnance (Captain Bacon) to the First Sea Lord (Lord Fisher) on the 21st of July 1908. What was proposed, in effect, was that Messrs. Vickers, Son & Maxim, who had been so successful in the design and manufacture of submarines, should be asked to undertake the construction of a large rigid airship of the Zeppelin type. After many meetings of the Committee of Imperial Defence, at which Captain Bacon propounded his views with great vigour, the committee recommended that the sum of £35,000 should be placed in the Navy Estimates for 1909-10, for the construction of an airship to be designed and built under Admiralty supervision. The Treasury agreed, and Messrs. Vickers's tender for the airship was accepted on the 7th of May 1909. The huge Cavendish Dock at Barrow-in-Furness was appropriated to the work, and the greatest possible secrecy was observed in all the preparations. A special section was formed to assist in the construction of the ship—Captain Murray F. Sueter, R.N., and, with him, Lieutenant Neville Usborne, Lieutenant C. P. Talbot, and Chief Artificer Engineer A. Sharpe. For two years public curiosity was kept alive on a diet of conjecture. A good part of this time was taken up in improvements and modifications of the design of the ship. When at last in May 1911 the shed was opened and the huge airship was brought out to her mooring-mast in the dock, those who had expected a larger and better Zeppelin seemed justified in their belief. The ship was 512 feet long and 48 feet in diameter, with a blunt bow and a pointed stern. Her capacity was approximately 700,000 cubic feet. The framework was made of a new alloy called 'duralumin', nearly as strong in tension as mild steel and not much heavier than aluminium. It was covered with 46,000 square yards of water-tight silk fabric, so treated with aluminium dust and rubber that the upper surface of the hull, which had to resist the rays of the sun, showed the silver sheen of a fish, while the lower surface, which had to resist the damp vapours of the water, was of a dull yellowish colour. The hydrogen was contained in seventeen gas-bags of rubbered fabric. The ship was fitted with two Wolseley motors of one hundred and eighty horse-power each, and with a whole series of vertical and horizontal rudders. She was popularly called the Mayfly—a name which, both in and out of Parliament, suggested to bright wits an ill-omened pun.

She never flew. For four days she remained tethered to the mooring-mast in the centre of the Cavendish Dock, and successfully completed her mooring trials. During this time the wind was rough, reaching in gusts a velocity of forty-five miles an hour. This wind, being a severer test than any previous airship had successfully encountered when moored in the open, proved the strength of the ship. But her very strength, and the completeness of her fittings, told against her in another way; the lift of an airship, consisting as it does of a small excess of buoyancy over weight, is always a matter of the most delicate and difficult calculation, and her lift proved to be insufficient. She was taken back into her shed, without mishap, and alterations were at once put in hand. On the 24th of September 1911 she was again drawn out of her shed to be transferred to the mooring-post; in the process she broke her back, and became a total wreck. The ensuing court of inquiry pronounced that the accident was due to structural weakness; the naval officers and men were exonerated from all blame.

This accident had a far-reaching effect. It disappointed public hopes and strengthened the case of objectors. There are always critics who take a certain mild pleasure in failure, not because they prefer it to success, but because they have predicted it. The pioneers of aeronautics could not afford to lose friends; they had none too many. The men in high authority at the Admiralty were not convinced that airships were a desirable and practicable addition to naval resources. They would all have died to save England, but they held that she was to be saved in the old way, on the sea. One gallant and distinguished admiral, when he first saw the Mayfly, said, 'It is the work of a lunatic'. The consequences of the failure were soon apparent. The president of the court of inquiry recommended to the First Sea Lord (Sir A. K. Wilson) that the policy of naval airship construction should, for the time, be abandoned. At a conference held on the 25th of January 1912, in the First Sea Lord's room at the Admiralty, it was decided, in accordance with this recommendation, that the airship experiments should be discontinued. Moreover, the special section, the nucleus of a naval air service, was, by the decision of the Admiralty, broken up, and Captain Sueter and his officers were returned to general service. When the construction of rigid airships was at last taken up again early in 1914, they were too late for the market; the heavy demands of the war delayed their completion, and no British rigid airship was in use at the time of the battle of Jutland.

It is to the credit of the pioneers of the Naval Air Service that when they were faced with this disaster, after years of fruitless effort, they did not lose heart or hope, but held on their course. Time was on their side. In the later autumn of 1911 the Committee of Imperial Defence, as shall be explained in the next chapter, appointed a technical sub-committee to give advice on the measures which should be taken to secure for the country an efficient aerial service. On the 5th of February 1912 Captain Sueter gave evidence to this body of experts, and sketched in broad outline his ideas for the development of a naval air service. Airships and aeroplanes, he said, were both required, and neither of them should be developed at the expense of the other. An airship had the great advantage that she could carry long-distance wireless apparatus, and could send or receive a message over a space of three hundred miles. She could stop her engines and drift over suspected places, for the detection of submarines and mines. The seaplane, he maintained, should also be developed, and he saw no insuperable difficulties in devising a machine that should be able to alight on either water or land and to rise again into the air from either. 'I think you have got a certain amount of intellect', he said, 'in the Navy to do it, and I think you have got a certain amount of intellect in the Army to do it. The two together, with the Advisory Committee—there are talented people there—and the manufacturers in the country; between us all we could devise something. We did not have great difficulty with the submarine boats; and that was all new at first.' The problem of the air, he held, was vital for the Navy; and when he was asked whether we must try to command the air as well as the sea, he replied, 'I think it will come to that. I do not say that we wish to do so, but I think we will be forced to do so.' In a memorandum submitted to the same sub-committee by Captain Bertram Dickson the meaning of the command of the air is more fully explained. 'In the case of a European war', he writes, between two countries, both sides would be equipped with large corps of aeroplanes, each trying to obtain information of the other, and to hide its own movements. The efforts which each would exert in order to hinder or prevent the enemy from obtaining information ... would lead to the inevitable result of a war in the air, for the supremacy of the air, by armed aeroplanes against each other. This fight for the supremacy of the air in future wars will be of the first and greatest importance, and when it has been won the land and sea forces of the loser will be at such a disadvantage that the war will certainly have to terminate at a much smaller loss in men and money to both sides.'

The whole matter is clearly stated in these passages. The people of Great Britain live in an island. They do not desire—they have never desired—to dominate the world, or to dictate to other peoples how they shall live. They do desire to be free of the world, and to take their luck in it, passing to and fro without hindrance. This freedom of theirs has repeatedly been imperilled by foreign powers, who have always desired a greater degree of uniformity and control than is tolerable to Britain. In order to keep their doors open the people of this island have been compelled to fight at sea, and have attained a measure of naval power which is sometimes called the mastery of the seas, but which, in essence, is no more than the obstinate and resolute assertion of their right to be the masters of themselves. They have been adventurers and pirates; they have never been tyrants. They fight desperately because they know that even on distant seas they are fighting for their lives, and for all that makes their lives worth living. Their many victories, under which they groan, have compelled them to learn the imperial art, an art which they practise not without skill, but reluctantly, and without zest. With the conquest of the air their task of self-defence has been doubled. It is not to be wondered at that those who were responsible for keeping open the gates of the sea should turn their eyes away from the new duty. But the new duty—command of the air, so to call it—was plainly visible to those who once looked at it. We must keep the highways open, or our freedom is gone. We must command the air. 'I do not say that we wish to do so,' said Captain Sueter, 'but I think we shall be forced to do so.' The whole of our naval history is summed up in that sentence; and the whole of our air policy is foretold.

The force that was to compel us was already in being. The science of aeronautics had passed from the experimental to the practical stage, and foreign powers were rapidly building up very formidable air forces. Of these foreign forces we naturally knew most of the French, for France was both our neighbour and our friend. In October 1911 a very full and illuminative report was supplied to the Government by Lieutenant Ralph Glyn, an officer attached to the newly-formed Air Battalion. It described, with reasoned comments, the aeronautical exercises carried out by the French air corps at the Camp de Châlons during the previous August. At that time the French War Ministry had at its disposal, so far as could be ascertained, something between two hundred and two hundred and twenty aeroplanes. The biplanes were all Farmans. The monoplanes, which were on the whole preferred by expert opinion to the biplanes, were of many types, all famous for achievement—Nieuports, Blériots, Deperdussins, R.E.P.'s, Antoinettes, and others. The methods of training were elaborate and complete, and the air corps were continually practised in co-operation with all other arms—infantry, cavalry, and artillery. 'There is no doubt at all', says the writer, 'but that the Germans have suddenly realized that the French Army since the general employment of aeroplanes with troops has improved its fighting efficiency by at least twenty per cent.... For the last five years the Germans have concentrated their whole attention upon the building, manœuvring, and employment with troops, of dirigibles. They have gained a slight advance over France, in fact, in this branch of aeronautics; but they have quite dropped behind in the question of heavier-than-air machines. France now after an equal period has just, and only just, formed a really efficient fighting aerial corps; and this lead of five years she is determined to maintain.'

This is not an over-statement. From the first the French, who had thought out the whole business, laid great stress on reconnaissance and control of artillery fire as the main uses of aircraft. For reconnaissance the aeroplanes were practised to co-operate with cavalry. For fire control official maps, divided into geometrical squares, so that a pair of numbers will identify a position within a score or so of yards, were supplied in duplicate to the pilots of the aeroplanes and to the commanding officers of batteries. The system of signalling employed was mostly primitive, but already in 1911 the French were experimenting with captive balloons which received the messages from the aeroplane, and by wireless, or some kind of visible signal, transmitted them to the guns. 'Practice', says Lieutenant Glyn, 'has made almost perfect a remarkable system which renders the efficient French artillery more formidable than ever.' Further, infantry were trained to co-operate with aircraft, so as to learn to take advantage of the new arm; and aerial photography was practised, under strict conditions of secrecy, with a surprising degree of success. In short, almost all the uses which later became the commonplaces of the war were exemplified in the French manœuvres of 1911. Battle in the air and the use of aircraft as a weapon of direct offence were later developments.

In October and November of the same year Captain F. H. Sykes, of the General Staff, and Captain J. D. B. Fulton, of the Air Battalion, visited many of the French military and civil aerodromes, and were present at the military aeroplane competition at Rheims. 'The trials held at Rheims', says Captain Sykes, 'are considerably in advance of anything yet attempted.' The machines were flown by the best available pilots, and were under the personal supervision of the makers and designers. Aerodromes were better and more numerous than in England; many of them were situated in wide plains, so that the learner could make his first cross-country flights over good even landing ground. Captain Sykes, in his report, suggests that aeroplane sheds should be erected and flying schools started at stations not very far apart from one another in England, so that cross-country training may be facilitated. 'These stations should be as near as possible', he adds, 'to where troops are quartered, so as to afford an opportunity for aeroplanes to work with troops on field days. The cost would, I think, be inconsiderable in comparison to the value gained.' This suggestion was carried out, but not until the war had compelled an immense expansion of the air force.
