HC Deb 12 December 1949 vol 470 c2335
4. Mr. Erroll

asked the Minister of Supply what is the present cost of research on civil aircraft development and ground control problems for civil aviation.

Mr. G. R. Strauss

A large part of the expenditure on aeronautical research and development is of benefit to both civil and military aviation. It is not, therefore possible to give a separate figure for the former.

Mr. Erroll

Can the Minister answer that part of the Question relating to ground control problems?

Mr. Strauss

Ground control is common to both.
