HC Deb 03 February 1943 vol 386 c874
18. Sir Leonard Lyle

asked the Secretary of State for Air whether members of the Royal Air Force Regiment are authorised in all cases to fire on low-flying enemy aeroplanes or whether, to avoid drawing return fire, they leave such firing to units of the Regular Army posted away from the airfields?

Sir A. Sinclair

The Royal Air Force Regiment fires on all aircraft identified as hostile.
