asked the Minister of Supply what research is now being carried out, or is contemplated, in piloted super sonic flight.

A considerable programme of research into the problems of piloted supersonic flight is being undertaken and a number of different types of supersonic Service aircraft are in course of development. I am not, of course, free to give details.

Are we now engaged upon research into piloted supersonic aircraft?

Certainly. That is what the Question was about.

Will the Minister make it clear: are we now engaged in research on piloted supersonic aircraft?

Yes. That is what I said.
