HC Deb 13 March 1940 vol 358 c1175
17. Mr. Levy

asked the Secretary of State for Air whether air-liners of the age and type of the missing Hannibal are being replaced by up-to-date aircraft; and how many semi-obsolete types are still engaged in civil air service?

Sir K. Wood

Air liners of the Hannibal class employed on the Empire Air Services are to be replaced by more up-to-date aircraft as soon as these can be made available. There are in addition 13 aircraft in use on those services which can be described as of semi-obsolete types, but are completely airworthy, having to pass the necessary airworthiness tests and periodic inspections. They have given excellent service on those routes and can continue to do so until it is possible for them to be replaced.
