§ Mr. J. Johnsonasked the Minister of Supply if he is aware that the engine testing of the Armstrong Siddeley Motors Limited at Ansty Aerodrome continues to cause annoyance to local residents; and what further discussions he has had to seek a reduction of the noise.
§ Mr. MaudlingDuring the past year. Messrs. Armstrong Siddeley have installed a further test house with mufflers and are about to install two more. No jet engines will in future be tested without muffllers. Some brief testing of other engines which cannot, as yet, be effectively silenced is necessary, but is confined to the day-time.
