HC Deb 19 June 1973 vol 858 c109W
Mr. Nicholas Edwards

asked the Secretary of State for Trade and Industry how many more supersonic trial flights by Concorde are to take place down the West Coast route.

Mr. Onslow

It is not possible to give a precise estimate; this will depend on the progress made in the flight development programme. Fifty flights were envisaged when the West Coast route was announced and 25 have taken place so far.
