§ 40. Mr. Anthony Greenwoodasked the Secretary of State for Air what steps are taken to prevent unauthorised persons trespassing upon Royal Air Force airfields and endangering the lives of aircrews.
§ Mr. A. HendersonR.A.F. airfields are generally enclosed by natural field boundaries and fencing of various types. Suitable warning notices are exhibited at intervals and some airfields are patrolled with police dogs at night. With an airfield perimeter of up to eight miles it is impossible to prevent trespass and the safety of aircrews must of necessity rest finally with the air traffic control staff responsible for the take off and landing of aircraft. In general trespassing is not a serious problem from the point of view of endangering the lives of aircrews.
