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. Bleriot 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.'
