HC Deb 25 May 1943 vol 389 c1407W
Mr. W. Brown

asked the Secretary of State for War whether his attention has been drawn to the Dufay air photo process which has recently been made available; and whether, in view of the moral value of this process, he will do everything possible to facilitate its development and use?

Sir J. Griǵǵ

I am having inquiries made into this.
