From what has been said it is evident that the Naval Wing of the Royal Flying Corps paid more attention than was paid by the Military Wing to the use of the aeroplane as a fighting machine. This difference naturally followed from the diverse tasks to be performed by the two branches of the air service. The Military Wing, small as it was, knew that it would be entrusted with the immense task of scouting for the expeditionary force, and that its business would be rather to avoid than to seek battle in the air. The Naval Wing, being entrusted first of all with the defence of the coast, aimed at doing something more than observing the movements of an attacking enemy. Thus in bomb-dropping and in machine-gunnery the Naval Wing was more advanced than the Military Wing. Both wings were active and alive with experiment, so that after a while experimental work which had originally been assigned to the factory and the Central Flying School was transferred to the Wing Headquarters. During the year 1913 wireless experiments were discontinued at the Central Flying School, and were concentrated at the Military Wing. There was a valuable measure of co-operation between the two wings. This co-operation was conspicuous, as has been seen, in wireless telegraphy, which was first applied to aircraft at Farnborough. The lighter-than-air craft, which belonged first to the army and then to the navy, were a valuable link between the two wings. Each wing was ready to learn from the other. In January 1914, by permission of the Admiralty, officers of the Military Wing witnessed the experiments made by the Naval Wing with bomb-dropping gear. If the Naval Wing in some respects made more material progress, it should be remembered that they received more material support. They were encouraged by the indefatigable Director of the Air Department, and received from the Admiralty larger grants of money than came to the Military Wing. No doubt a certain spirit of rivalry made itself felt. Service loyalty is a strong passion, and the main tendency, before the war, was for the two branches of the air service to drift apart, and to attach themselves closely, the one to the army, the other to the navy.
