§ Mr. RedmondTo ask the Secretary of State for Defence how many of the aircraft observed by Skyguard radar since June 1989 were flying at medium level within the meaning of his answer of 14 July,Official Report, column 560.
§ Mr. HanleyIn my answer of 14 July—Official Report, column 560—medium level was intended to refer to aircraft operating at heights above 2,000 ft above ground level. Reports on Skyguard deployments prior to November 1992, during which 1,175 military aircraft were observed, do not distinguish between aircraft operating at low and at medium level. Of the 627 aircraft observed by Skyguard since that time, 243 were operating at medium level.
