§ 61. Mr. Montague
asked the Under-Secretary of State for Air how many hours of flying for the purpose of advertising commercially took place over the built-up area of London in 1937?
§ Lieut.-Colonel Muirhead
I would refer the hon. Member to the first part of the reply given to him on 3rd February, to which I am afraid I can add nothing.
§ Mr. Grant-Ferris
Is my hon. and gallant Friend convinced that these aircraft will always fly at a safe height?
