HC Deb 15 February 1991 vol 185 c621W
Dr. Thomas

To ask the Secretary of State for Defence what proportion of low-flying activity over the United Kingdom since 1 October 1990 has been carried out by foreign air forces other than those of the United States.

Mr. Kenneth Carlisle

Between 1 October 1990 and 31 December 1991 (the most recent date for which statistics are available) flights by foreign aircraft, other than those of the United States Air Force based in this country, represented under 1 per cent. of the total number of flights in the United Kingdom low flying system.
