§ Sir F. SYKESasked the Under-Secretary of State for Air, in respect of the past 12 months, the ratio of man hours employed in the maintenance of aircraft and engines on the establishment of units of the Royal Air Force, other than store and repair depots, as compared with the number of machine and engine flying hours, respectively?
§ Mr. LEACHTo obtain this information would entail a great deal of detailed calculation by the units concerned, the value of which would not, I think, compensate for the time which would have to be devoted to it by commanding and other officers.
