§ 68. Mr. Caryasked the Secretary of State for Air whether he will state briefly the military recommendations which are assumed to make the black-out regulations an essential part of our defences?
§ The Secretary of State for Air (Sir Kingsley Wood)The purpose of the black-out is to render air navigation, the location of targets and accurate bomb-aiming more difficult, and practical experience has shown that it does in fact have these effects.
§ Mr. CaryIs it not a fact that in the Sylt raid the fires started by the first bombers guided other bombers to their targets, thus proving the German black-out to be quite useless?
§ Sir K. WoodObviously, I cannot comment on that.
§ Sir H. WilliamsCan the Minister give any place in this country where the black-out has proved effective?
§ Sir K. WoodThat is another matter.
