HC Deb 25 July 1967 vol 751 cc97-8W
86. Mr. Webster

asked the Minister of Technology when he proposes to terminate the experimental sonic bangs in the neighbourhood of Bristol.

Mr. Benn

The current series of tests has now ended.

88. Mr. Onslow

asked the Minister of Technology, whether he has any plans to conduct sonic boom tests during the hours of darkness.

Mr. Benn

None, at present.

89. Mr. Worsley

asked 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. Benn

They should write to the Ministry of Technology, St. Giles High Street, London, W.C.2, and mark the envelope "Sonic Bangs".

Mr. Brooks

asked 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. Benn

The 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. Brooks

asked 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. Benn

The 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.
