asked the Under-Secretary of State for Air (1) whether the Lorenz system, now installed at Croydon airport, is proving entirely satisfactory when used by Douglas aeroplanes belonging to Swiss Air;(2) whether the Lorenz system now installed at Croydon airport is proving entirely satisfactory when used by Douglas aeroplanes belonging to the K.L.M. Company?

I understand that the Douglas aircraft belonging to Swiss Air and K.L.M. that are fitted with Lorenz receivers find the Lorenz beacon at Croydon airport quite satisfactory.
