HC Deb 28 July 1937 vol 326 c3091
73. Mr. Chorlton

asked the Under-Secretary of State for Air whether, in view of the safety against fire risks from the use of the heavy oil engine in aircraft, he can report what expansion in their use for civil aircraft has taken place, and give the number now in use as compared with six months ago; also whether there are any in use for military aircraft?

Lieut.-Colonel Muirhead

There are at present no heavy oil engines in use in civil aircraft registered in the United Kingdom or in Royal Air Force squadrons, but experiments have been carried out with such engines, and these will be continued.

Mr. Chorlton

If these engines have been successful so long ago as Airship 101, is it not a gross neglect on the part of the Ministry that nothing has been done to employ them?

Lieut.-Colonel Muirhead

I do not think so.
