§ Mr. MACKINDERasked the Secretary of State for Air whether he is aware that night-flying practice is taking place at frequent intervals from the Biggin Hill aerodrome, and that this is causing serious inconvenience to the inhabitants of Bromley and district; and whether he will arrange for the necessary night-flying operations to be conducted away from large centres of populations?
§ Sir S. HOAREIf the defence of London by air is to be efficient, night-flying practice from the aerodromes allotted to units comprised in the scheme of defence is essential. It is, I fear, impossible entirely to avoid disturbance to people living in the vicinity of such aerodromes, but the disturbance is, and will he, strictly limited to that which is unavoidable if training is not to suffer.
