vhich will suffice to give the operating authorities u
sufficient security of tenure to warrant the exceptional
financial outlay and risKS which the scheiTie will entail fi
The scheMe offers such financial terms ar
should enable the luno sum payments to be Xept within
limits which will preclude any substantial increase in the
normal postal rate. The full details arc elaborated in
the printed memorandum, enclosed herewith, although it is
realised that this is not in a form suitable for direct
presentation to the Government of a country outside the
British Empire. In addition to the Empire Governments
served by the routes, the Governments of the Gudun, Egypt,
Palestine ana Ira^ ore being invited to participate.
It is, however, an inevitable corollary of the
Scheme that the various participating Governments should,
as indicated in the printed memorandum, accept
responsibility for providing adequate night flying
facilities and all other adjuncts for an efficient ground
organisation, to ensure the successful application of the
proposals. It will be obvious that the journey time
schedules can only be achieved if night flying is fairly
continuous unless machines are to be used which provide
an exceptionally high rate of speed and give longer periods
upon the ground. His lajesty's Government, however, as
the result of an exhaustive review of the whole situation,
are convinced that excessively high speeds can be purchased
at too daar a price, for instance, if the average cruising
speed under the Scheme were to be increased to 200 miles
per hour (as is within the limits of technical
practicability) the total costs involved would be increased
