HC Deb 12 December 1963 vol 686 c113W
61. Mr. Cronin

asked the Secretary of State for Air why photographs of the TSR2 aircraft and other information about it, hitherto secret, were released to the Press.

Mr. H. Fraser

It was considered that the stage had been reached, in the aircraft's development, when limited information could properly and usefully be made available to the public.
