HC Deb 26 June 1968 vol 767 c100W
Mr. Nott

asked the Minister of Technology to what extent the Land's End area has been the site for British or foreign testing of sonic booms within the past 10 days; and why the local population was not forewarned in accordance with normal practice.

Mr. Stonehouse

No tests of public response to sonic bangs have taken place in the Land's End area. Any such test would be preceded by a public announcement in accordance with the undertaking given last year. Nor have Ministry of Technology aircraft carried out any R. & D. flights at supersonic speed in the area.
