HC Deb 09 December 1946 vol 431 c743
36. Mr. Symonds

asked the Minister of Supply if he will investigate the claim, particulars of which have been sent to him, of the development by the Ryan Aeronautical Corporation in the U.S.A., of a light-weight stainless-steel muffler to eliminate 90 per cent, of the noise in 65-85 horsepower aircraft engines; and if he will arrange for the muffler, if successful, to be produced in this country and to be fitted to all training aircraft used near centres of population.

Mr. Wilmot

We have asked for particulars from America to enable us to make a full technical examination of this device.

Mr. Symonds

Will the right hon. Gentleman keep the Air Ministry informed, as most of the trouble is caused by Tiger Moths used by the E.F.T.S.?
