One particular achievement was greater than all the rest. When flight began it attracted men of romantic and adventurous temper, some of whom were much concerned with their own performances and had a natural liking for display. If these tendencies had been encouraged, or even permitted, they would have ruined the corps. The staff, to a man, set their faces like flint against all such indulgences. Publicity, advertisement, the rubbish of popular applause, were anathema to them. What they sought to create was a service temper, and they were so successful that the typical pilot of the war was as modest and dutiful as a lieutenant of infantry. The building up of the Flying Corps on these lines, remote from the public gaze, deprived it of popular support, but it gained for it what was a thousand times more valuable—a severe code of duty, a high standard of quiet courage, and an immense corporate pride. To have kept the infant corps and all its doings in the public eye would have been as disastrous an experiment as to attempt to educate a child on the music-hall stage.

A great part of the early work of the Flying Corps was experimental. Various kinds of experiment were assigned by the corps headquarters to the several squadrons, and the headquarters staff took care that any success achieved by one squadron should become the rule for the betterment of all. An experimental branch of the Military Wing was formed in March 1913 under Major Herbert Musgrave; it dealt, among other things, with experimental work in connexion with ballooning, kiting, wireless telegraphy, photography, meteorology, bomb-dropping, musketry, and gunnery, and co-operation with artillery. Major Musgrave deserves more than a passing mention in any military history of the air. After serving throughout the South African War as a lieutenant in the Royal Engineers he had passed through the Staff College. The possibilities of aviation very early took possession of his mind. In 1909, from the cliffs of Dover, he saw M. Blériot arrive in a monoplane, and was so impressed by the sight that he went straight to the War Office to draw attention to the military significance of this portent, and its threat to our insular security. From this time forward his mind was set on aeronautics. He applied for military aviation service before the Flying Corps was formed, and in May 1912 repeated his application. 'A Staff Officer', he noted in his diary, 'should know the capabilities of aviation. He should be able to observe from an aeroplane and to travel by aeroplane with dispatches.' At last, in October 1912, during a short period of leave, he learned to fly at the Bristol Flying School on Salisbury Plain. In the following spring he was gazetted a squadron commander in the Royal Flying Corps. He was at once appointed assistant commandant and officer in charge of experiments. His utility to the Flying Corps, while it was in the making, was immense. He urged that new squadrons should be formed even while machines were lacking, so that the organization and discipline should be perfected in advance. The flying training of the corps, he insisted, should always have a clear military purpose in view. He was no militarist, but he was a good soldier, and he knew the imminence of war with Germany. As early as December 1911, in a lecture which he delivered in Malta, he predicted the war. 'When it comes,' he said, 'be assured it will come suddenly. We shall wake up one night, and find ourselves at war.... Another thing is certain. This war will be no walk-over.... In the military sphere it will be the hardest, fiercest, and bloodiest struggle we have ever had to face; let us fully make up our minds to that, and probably every one of us here to-night will take part in it. We need not be afraid of overdoing our preparations.'

For two years Major Musgrave worked hard in helping to prepare the Flying Corps for its coming ordeal. In the spring of 1914 a headquarters flight was placed at his disposal for technical work in many kinds. Up to this time there had been two kinds of experimental work; the National Physical Laboratory was responsible for purely scientific experiments, while the commanders of squadrons tested new ideas in practice. But these two sets of men worked under very different conditions, and neither of them fully understood the aims and difficulties of the other branch. The headquarters flight was intended to serve as a link between theory and practice. Major Musgrave gave special attention to wireless telegraphy, and with the assistance of Lieutenants D. S. Lewis and B. T. James, both also of the Royal Engineers and both pioneers of wireless, he made good progress in its practical application to the needs of the Flying Corps. When the war came, the headquarters flight was broken up in order to bring the four original squadrons up to strength, but the wireless section was attached for a time to No. 4 Squadron, and in September 1914 a headquarters wireless unit was formed at Fère-en-Tardenois in France, with Major Musgrave in command. From this unit the whole wireless telegraphy organization of the Royal Flying Corps was gradually developed. In December 1914 the unit was enlarged, and became No. 9 Squadron stationed at headquarters. Having worked out all details for the supply of wireless machines to the squadrons in the field, Major Musgrave in March 1915 left the Royal Flying Corps to take up duty with the staff of the army. He was severely wounded in August 1916. Almost two years later, on the night of the 2nd of June 1918, having persuaded a battalion commander to let him accompany a patrol, he was killed by a rifle grenade, inside the German lines. He desired no personal advancement, and would have thought no other honour so great as to die for his country. Such men, though the records of their lives are buried under a mass of tedious detail, are the engineers of victory.

When the airships were handed over to the navy, it became necessary to reorganize No. 1 Squadron as an aeroplane squadron. This was put in hand on the 1st of May 1914, and was not completed when the war broke out. The senior aeroplane squadrons of the Military Wing were, therefore, No. 2 Squadron under Major Burke, and No. 3 Squadron under Major Brooke-Popham.

The officers of these squadrons, to whom it fell to set the example and to show the way, were a remarkable group of pioneers. Some of them were accomplished flyers, who took delight in the mastery of the air. But none of them practised the art for the art's sake. They were not virtuosos, bent on exhibiting the heights to which individual skill can attain. They did not play a lone hand. The risks that they took were the risks, not of adventure, but of duty. They were soldiers first. One and all they were impressed with the importance of military aviation for their country's need. 'It has got to come,' said Captain Patrick Hamilton, 'and we have got to do it.' Their lives were pledged to their country, and until their country should call for them, were held in trust, not to be lightly thrown away. Some were called early, during the exercises of peace; others during the war. Others again, a minority, were marked down for a third chance, and were given the duty of carrying on, through the war and after it. The time of the call, early or late, made no difference; the work of the corps was not interrupted. When Captain Eustace Loraine, the first to go, was killed with his passenger, Staff-Sergeant R. H. V. Wilson, near Stonehenge, on the 5th of July 1912, the order was issued that flying would go on as usual that evening. An order like this not only creates a tradition, it pays the right honour to the dead, who died on duty no less than if they had been brought down by the guns of the enemy. The casualties of the first summer were not light in proportion to the strength of the corps, and in one respect were very heavy, for almost all of those who were killed were creators and founders, whose work and influence would have been invaluable in building up the corps. They could ill be spared. They left nothing but their example; yet any one who remembers what the Flying Corps achieved during the war may well wonder whether that example does not count for as much as a long life of devoted service.

Captain Eustace Broke Loraine had served with the Grenadier Guards in the South African War. His great-grandfather was the famous British admiral, Sir Philip Broke, who in 1813 commanded H.M.S. Shannon, and after a fifteen minutes' battle outside the port of New York compelled the surrender of the United States frigate Chesapeake. That battle, it has been truly said, was won before it was fought; the Shannon had been many years cruising at sea; she was in perfect fighting trim, her men were disciplined and her gunners practised. The men of the Chesapeake were fresh from the shore, strangers to each other and to their officers, so that the heavier armament of the Chesapeake was of no avail. When Captain Loraine joined the Flying Corps he applied his great-grandfather's methods, and set himself by study, care, discipline, and skill to prepare the materials of victory. He was a highly skilled pilot, perhaps overbold. The machine he was flying on the 5th of July was the fast two-seater Nieuport monoplane on which Lieutenant Barrington-Kennett had achieved some records. It seems that he attempted too sharp a turn, lost flying speed, side-slipped, and nose-dived. He was only a few hundred feet up, and there was no time to save the crash. Those who knew him believe that he would have done much for the Flying Corps. He spared no pains to understand his business, and to make theory and practice help each other. Staff-Sergeant Wilson, who was killed with him, was the senior technical non-commissioned officer of No. 3 Squadron, a first-class man, and a heavy loss.

Other fatalities were to follow. On the 6th of September Captain Patrick Hamilton and Lieutenant A. Wyness-Stuart, flying a hundred horse-power Deperdussin monoplane on reconnaissance duties connected with the cavalry divisional training, crashed and were killed at Graveley, near Hitchin. Four days later Lieutenant E. Hotchkiss and Lieutenant C. A. Bettington, flying an eighty horse-power Bristol monoplane from Larkhill to Cambridge, crashed and were killed at Wolvercote, near Oxford. A committee was appointed to investigate these accidents, and in the meantime an order was issued by the War Office forbidding the use of monoplanes in the Royal Flying Corps. This order altered the scheme for the army manœuvres, where it had been intended to allot a squadron of monoplanes to one force and a squadron of biplanes to the other, in order to compare results. No. 3 Squadron, nevertheless, assembled near Cambridge in such strength as it could muster; there were Major Brooke-Popham, Captain Fox, and Second Lieutenant G. de Havilland of the squadron; these were joined by Mr. Cody, who came as a civilian with his own machine, and by officers of the Naval Air Service, who flew Short biplanes.

The ban on monoplanes, it may be remarked in passing, was a heavy blow to one of the earliest pioneers of aviation in this country. Mr. L. Howard Flanders, who had worked with Mr. A. V. Roe at Lea Marshes, and had designed the 'Pup' monoplane for Mr. J. V. Neale at Brooklands, had subsequently formed a company for the building of aeroplanes, with works at Richmond. He obtained a War Office contract for four monoplanes, but when, after trial, he was engaged in reconstructing the under-carriages, the use of the monoplane was forbidden to army pilots. This and other disappointments put an end to Mr. Flanders's building activities, but his name deserves record among the pioneers.

When Lieutenant B. H. Barrington-Kennett of the Grenadier Guards became adjutant of the Military Wing of the Royal Flying Corps he made a vow that the corps should combine the smartness of the Guards with the efficiency of the Sappers. In spite of difficulties and disasters, the corps went far, in the first two years of its existence, towards attaining that ideal. In the summer of 1912 the Central Flying School at Upavon got to work, and thenceforward supplied a steady stream of trained reinforcements for the corps. There was inevitable delay at first; but as soon as some of the new wooden buildings were nearing completion they were taken over, and on the 19th of June the school was opened. The plan was that there should be three courses every year, each of them lasting three months and passing on its graduates for further training either with the military squadrons or at the naval school. The first course began on the 17th of August 1912, and was not completed until the end of December, but the subsequent courses were punctually completed in the time prescribed. The delay in the first course was due chiefly to a shortage of machines. The use of monoplanes was forbidden, and the nineteen pupils who presented themselves in August had to be instructed on the only four available biplanes, which were soon damaged by the maiden efforts of the learners. For a short time the pupils were sent on leave, and the school was closed; then new machines and new recruits began to arrive, and the work of education went forward. Besides the main business of flying, the pupils were instructed and examined in map-reading and signalling, the management of the internal-combustion engine, and the theoretical aspects of the art of reconnaissance. Of a total of thirty-four pupils who were examined at the end of the course, only two failed to pass. During the next year and a half, up to the very eve of the war, the work of the school went on steadily, with improving material and increasing efficiency. There were three fatal accidents: on the 3rd of October 1913 Major G. C. Merrick was killed on a Short biplane; on the 10th of March 1914 Captain C. P. Downer, on a B.E. biplane; and on the 19th of March 1914 Lieutenant H. F. Treeby, on a Maurice Farman biplane. On an average about thirty officers passed out from the school, into one branch or another of the service, at the end of each course. Most of these were army officers, but there was also a fair number of naval officers, marine officers, and naval volunteer and civilian reservists. The school was run on army lines, so that a good deal of adjustment and tact were called for in dealing with the navy pupils, who were accustomed to a more generous scale of allowances and a different system of discipline. But the resolve to make a success of the new air force prevailed over lesser difficulties, and harmony was maintained.

The steady flow of recruits from Upavon soon enabled the Military Wing of the Royal Flying Corps to form new squadrons. These squadrons all started in the same fashion; they hived off, so to say, from the earlier squadrons. As early as September 1912, a part of Major Burke's squadron, stationed at Farnborough, was detached, and became the basis of No. 4 Squadron, commanded by Major G. H. Raleigh, of the Essex Regiment, who had joined the Air Battalion just before the birth of the Royal Flying Corps. In August 1913 a single flight of Major Brooke-Popham's squadron became the basis of No. 5 Squadron, under Major J. F. A. Higgins. In January 1914 No. 6 Squadron, under Captain J. H. W. Becke, of the Notts. and Derby Regiment, and in May 1914 No. 7 Squadron, which was commanded later by Major J. M. Salmond, began to be formed at Farnborough.
