HC Deb 27 June 1940 vol 362 c607W
Mr. Joel

asked the Home Secretary whether he can now state any lessons derived from recent enemy air visitation affecting the value of steel shelters, brick shelters and the different forms of protecting windows against blast from bombs?

Sir J. Anderson

I would refer my hon. Friend to the answer which I gave yesterday to a Question by the hon. Member for Tonbridge (Sir A. Baillie). Experience, so far, is reassuring but there has not yet been a sufficient body of it on which to form judgments. Hon. Members may like to know that, in anticipation of bombing attacks I was able, with the welcome co-operation of the Cement and Concrete Association, to build up a staff for the purpose of investigating the effects of bombing on the spot, and that detailed reports on all recent raids have been within a very brief space of time in the hands of my research department, where they are studied exhaustively.
