HC Deb 11 February 1975 vol 886 cc95-6W
25. Sir David Renton

asked the Secretary of State for Defence whether he is aware that there has been no effective method of noise suppression for the ground testing of aircraft at Alconbury air base since midsummer 1974; and whether he will consult with the United States Air Force and other authorities concerned in order to ensure that such noise suppression equipment is installed as quickly as possible.

Mr. John

Yes. The United States Air Force authorities are fully aware of the problem and have taken steps to reduce engine testing at Alconbury until noise-suppression equipment is installed.
