§ 32. Mr. Walkden
asked the Secretary of State for War what progress has been 2839 made in the provision of effective rangefinders or predictors for use with antiaircraft guns; whether such appliances have been thoroughly tested on robot aeroplanes or by other means; and whether he can give any assurance that an air force attacking this country could now be broken by anti-aircraft artillery working with such supplemental equipment?
§ Mr. Hore-Belisha
The hon. Member can hardly expect me to make public information of this character.
