HC Deb 16 April 1973 vol 855 c7W
41. Mr. Nicholas Edwards

asked the Secretary of State for Trade and Industry what measurements of Shockwaves were taken at St. David's in Pembrokeshire on Thursday 12th April during Concorde's supersonic flight.

Mr. Michael Heseltine

The overpressure measured at St. David's Cathedral was 1½ lb./square foot.

Mr. Biffen

asked the Secretary of State for Trade and Industry what representations he has received concerning permission to start productifion on Concorde aircraft numbers 17 to 22; to what extent such permission will depend upon receipt of firm orders; and if he will make a statement.

Mr. Michael Heseltine

The manufacturers have made no request for permission to start full production at this stage on aircraft 17–22. The decision on starting manufacture of further aircraft will take full account of the market situations but the Governments must also have regard to other factors, such as the need to preserve manufacturing continuity, employment and the control of costs.
