HC Deb 20 February 1978 vol 944 c533W
Mr. Gwynfor Evans

asked the Secretary of State for Defence what is the mileage flown over Wales in authorised flights by low-flying jet military planes from whatever airfield within or without Wales; and what this is expressed as a percentage of the total mileage flown by such aircraft over Great Britain

Mr. Wellbeloved

I regret that my Department does not maintain records of this nature, but I can say that on average some 10 per cent. to 11 per cent. of military low flying takes place over Wales, which occupies about 9 per cent. of the land area of Great Britain.
