asked the Under-Secretary of State for Air what steps his Department, take to prevent the erection of overhead electricity cables within one mile of any military aerodrome in this country; under what Acts such action is taken; and in how many cases schemes for the erection of such lines have had to be abandoned during the past five years on account of such refusal?

Administrative arrangements have been in existence for some years whereby all proposals for the erection of overhead electricity cables which may affect the safety of aircraft are referred to the Air Ministry for consideration. If there is any objection from this point of view, the matter is represented to the Electricity Commis- sioners, usually with an alternative suggestion, such as the diversion of the line or the placing of a section underground. The arrangements with the Commissioners are interdepartmental and administrative rather than statutory in their nature. So far as can be ascertained, no scheme for the erection of overhead cables has been abandoned as a result of Air Ministry objections, but a number of lines have been diverted or placed underground.

Is my right hon. Friend aware that the policy of his Department is stopping the development of electrical supplies in the villages north of Bicester at the present time, and does he not think that in future this will increase the difficulties of obtaining further sites for any aerodromes that may be wanted?

No, Sir. I am not aware of that fact, but I do know that it is the duty of the Air Ministry, both as regards the Air Force, and the State, to protect our pilots and aircraft from any unnecessary danger.

Will the right hon. Gentleman consider the suggestion that his Department should pay for the increased cost of laying these lines underground?
