HC Deb 09 March 1966 vol 725 c544W
99. Mr. Allaun

asked the Minister of Aviation if he will prohibit the testing of military aircraft at supersonic speeds over thickly populated areas.

Mr. Mulley

A complete prohibition would be impracticable, but the testing of military aircraft at supersonic speeds is, in fact, usually carried out over the sea or over sparsely populated areas.
