§ Sir G. STRICKLANDasked the Secretary of State for Air whether be is prepared to make further inquiries as to the adoption of underground hangars by foreign Powers; and whether he is prepared to obtain estimates for their construction at selected sites within the Empire, in view of the necessity to establish confidence as to ability to reply to aggression from the air?
§ Sir S. HOARESo far as I am aware no foreign Powers have adopted underground hangars, presumably for the reason stated in the reply to my hon. Friend on 15th July last. That reply was based on the estimated cost of such a method of construction, and I do not think that further estimates are necessary.
