My advisers are fully aware of the possibilities of various methods of grass-drying, including the Newton process; but, as explained in the course of the Debate on Air Estimates at the Committee stage, technical and operational requirements preclude the use on any large scale of grass mown from aerodromes as cattle food.
My right hon. Friend is in close touch with the Minister of Agriculture in connection with this matter. Unfortunately, for aerodrome surface purposes we have to grow a particularly hard sort of grass which does not lend itself to drying. On the other hand. I shall be glad to look into any case of any particular aerodrome.
As indicated in the course of the Debate on Air Estimates at the Report stage, the desirability of obtaining as complete a film record of the air war as operational and technical considerations permit is fully recognised, and arrangements to this end have been made. As regards the second part of the Question, the formation of a special R.A.F. film unit is not at present contemplated.
Can the Minister say whether the recent reports in the Press to the effect that the Royal Air Force were to take operational films in colour were issued with the authority of his Department, and, if so, is there any reason why that statement could not have been made in the Debate on the Air Estimates?
I have not seen the statement. Film cameras have been installed in certain Royal Air Force aircraft, and these cameras are on loan from various sources. It is proposed that these cameras should be operated by Royal Air Force personnel, who are fully qualified to handle them as well as to fulfil their Royal Air Force duties. I cannot say anything about colour films, but I should have thought it was extremely doubtful whether they could be used with much benefit during night-bombing raids.
