72. Mr. PERKINS

asked the Under-Secretary of State for Air which Royal Air Force aerodromes are equipped with facilities for fog landings, such as are in use at Heston airport; and how many pilots in the Royal Air Force have any experience of this new invention?

Sir P. SASSOON

The equipment referred to is not in use in the Royal Air Force, but certain aircraft are now being fitted with fog-landing apparatus for experimental purposes.
