§ Then there is the problem of research, a problem that is the more urgent from the fact that, the smaller the force, the 1614 more vital is research. With the resources at our disposal we are trying to hold the balance between pure and applied research. Certainly the various organisations concerned, the Department of Supply and Research at the Air Ministry, the Aeronautical Research Committee, the National Physical Laboratory, the Royal Aircraft Establishment at Farnborough, and certain of the Universities seem to be working in close co-operation. Perhaps in some future Debate I shall have an opportunity of going into greater detail on this subject. Let me only say that we are at present experimenting in particular upon control of aircraft at low speeds, the use of crude oil instead of petrol for fuel, metal construction, and the many problems connected with economy in flying. The research upon helicopters is beginning to reach the stage of full scale experiment, and I propose to advertise prizes to the amount of £50,000 for a competition in connection with this field of experiment. I am also hoping to be able to make a small grant for the encouragement of gliding.
