W. Keith Hancock and Margaret M. Gowing, British War Economy — Chapter VIII.
“ All that is here required is an outline of the strategical concepts in which economic policy was framed. It was realised in 1941 that the decision to expand the production of bombers could hardly begin to produce important military effects until 1942-43. Even then, the war might drag out to an appalling length if the only way of ending it was to hammer German productive power and morale from the air. The Germans, therefore, would have to be speeded down the road of collapse by direct military assault. Even in the years of desperate British defence, the British planners looked forward to D-Day. ”
