We would urge that it is possible to pay too high a price for this co-operation and that the time has come T has frequently been said that what aviation has to offer to the for the Government—for presumably this, in these days of nationali travelling public is speed. Vis-â-vis other forms of transport zation, is a matter of national policy—to have the strength to I this is no doubt true but it must never be forgotten that it is a say that British Air Services at least should be made safe by the special requirement superimposed upon the demands made on all adoption of devices with which British airports and aeroplanes can forms of locomotion—that they should be safe and reliable. be equipped. If other countries do not choose to take advantage of In view of recent experiences it can, we suggest, scarcely be urged these facilities by installing reciprocal equipment in their aeroplanes that a form of transport which, in its present inchoate stage of ex that is their lookout.

A Matter of Equipment In considering the causes of these accidents it is reasonably clear that the fault lies not in the aeroplanes themselves, nor in the piloting Available Aids —though some of the blame may be attachable in some instances to So far as the approach to an airport is concerned the putting into the navigation. The responsibility lies with the organization and operation of Ground Control Approach would be of at least some provision of equipment for taking off, flying and landing in condi assistance to a pilot coming in to land ; pending a settlement of the tions of low visibility.

The mind has only to be cast for this purpose. There must be any quantity of the various pieces of back a couple of years for it to recall innumerable occasions when a equipment available in R.A.F. stores ; from which we suggest they steady stream of R.A.F. bombers could be heard passing overhead should be dug out.
