§ 110. Mr. Brooksasked the Minister of Aviation where and when he proposes that tests be conducted into the long-term physical and psychological effects upon the British people of sonic bangs of the intensity and frequency of 220W occurrence likely to be associated with supersonic civil airliner fleets of the next decade.
§ Mr. MulleyI am considering whether it is necessary to carry out a series of sonic bang tests. Previous experiments and experience in this and other countries suggest however that there are unlikely to be long-term physical and psychological effects upon people of sonic bangs of the intensity and periodicity likely to be associated with supersonic civil airliner fleets of the next decade.
