§ 86. Mr. Websterasked the Minister of Technology when he proposes to terminate the experimental sonic bangs in the neighbourhood of Bristol.
§ 88. Mr. Onslowasked the Minister of Technology, whether he has any plans to conduct sonic boom tests during the hours of darkness.
§ 89. Mr. Worsleyasked the Minister of Technology what is the correct procedure for members of the public who wish to complain of, or report on, sonic booms to his Department.
§ Mr. BennThey should write to the Ministry of Technology, St. Giles High98W Street, London, W.C.2, and mark the envelope "Sonic Bangs".
§ Mr. Brooksasked the Minister of Technology when he intends to instal an adequate number of telephone lines to receive the complaints over sonic booms being sent to his department.
§ Mr. BennThe number of lines available were increased substantially when it became apparent that many people preferred to telephone rather than write, and as a result the delays in getting through were reduced.
§ Mr. Brooksasked the Minister of Technology by what means he measures the true volume of public disquiet over sonic boom tests, when telephone lines to his Department are jammed for long periods.
§ Mr. BennThe recent tests did not create booms comparable to those that will be made by supersonic airliners; and a public opinion poll would have proved nothing. Later tests—if they are held—would provide an opportunity for a scientific survey of public reaction. No decision on future tests has yet been made.
