HC Deb 15 December 1938 vol 342 c2216W
Mr. Perkins

asked the Secretary of State for Air why the Royal Air Force Flying Training Manual, Part I, Land-planes, has been withdrawn from sale?

Captain Balfour

As a result of a recent review of Air Ministry publications the Flying Training Manual, Part I, Land-planes, was re-classified as "For Official Use Only," and has consequently been withdrawn from public sale.
