asked the Minister of Supply whether the prohibition on the deliberate creation of supersonic bangs extends to aircraft flying over Bitteswell aerodrome, near Rugby

:Supersonic flight, and the sound waves associated with it, is an essential part of the testing of high-speed modern aircraft, such as those manufactured at Bitteswell. However, within the limits of what is practicable, every effort is made to reduce disturbance to the public to the minimum.
