He believed that they would be able to build up a system that would very materially assist the general system of defence against air attack.
Experience, Sir Samuel added, was tending to show that whilst you could not prevent a raid a certain number of aeroplanes would always get through you could so organize defence as to make it very dangerous to the attacking forces.
With a combination of a strong air force, effective anti-aircraft guns and other anti-aircraft defences, and of a well-organized system of passive defence upon the ground, you could ensure two great objectives. You could prevent panic in great centres of population and you could ensure continuation of essential services, upon which a highly developed civillization depended.—Reuter.
