HC Deb 06 April 1982 vol 21 c311W
Mr. Wigley

asked the Secretary of State for Defence how many aircraft exercises at (a) about 200 ft or less and (b) under 500 ft on overland flights in Wales have been authorised over the last six months; and how many of these exercises took place between 1700 hours and 0800 hours.

Mr. Wiggin

In the six months ending 31 January 1982, 8,366 miltary training flights were conducted over Wales at heights below 500 ft. None of these flights was lower than 250 ft. It is impossible to define the precise times without disproportionate effort, but almost all of these flights took place between 0700 and 2300 hours, the normal daily period for low level training.
