Captain A. EVANSasked the Secretary of State for Air whether he is willing to carry out experiments over London in fog dispersion; and if his attention has been drawn to reports of alleged success by the American air service with sand electrically charged from aeroplanes?
§ Sir S. HOAREThe progress of the American experiments, which were, it is understood, of a private nature, has been reviewed by the Air Ministry from time 1341W to time. Scientific opinion, both in England and America, is not, however, convinced that the experiments are based on sound principles, nor satisfied with the evidence of success so far made public, and the Air Ministry cannot, therefore, advise the undertaking of the necessarily expensive tests involved.
