VERY great deal, quite possibly a great deal more than one can realise at the moment, may depend upon the deci- sions made and the action taken by the Air Ministry during the next few weeks on the subject of light 'planes. If the right course is followed we believe that 1925 wrill go down in history as marking the real beginning of popular aviation. A false step may easily result in retarding progress and render the work of the last few years futile. w« *!L t i We mav truly be said to be at the partingWonderful . ,. - , .. r „ ,, r Opportunity °* tne ways- and u we follow the wrong road the delay may be far-reaching. The position is already well known to readers of FLIGHT, and there is little need to go into details concerning the development of the light 'plane during the last couple of years. Put very briefly the whole history may be summed up telegrammati- cally as follows": Rhon gliders, 1921-22; Itford gliders, 1922 ; Lympne light 'plane single-seaters, 1923; Lympne light plane two-seaters, 1924. Logically the next entry should read: Lympne " not- quite-so-light 'planes," 1925, and from all indications that is what is about to happen. In a way it is deplorable, as it seems to indicate the burial of an ideal, but those of us who have followed flying since its beginning have had to bury a good many ideals. There is surely nobody who can fail to regret that the ideal which we had set ourselves : that of flying small aeroplanes with engines of really low power<s should have been found unattainable. Technically it has been demonstrated that, whatever official statements to the contrary, it is possible to fly with very small engines, but it seems to be an incontrovertible fact that as the size of the engine decreases so the cost of the machine increases. This is, of course, to be expected from first prin- ciples, since a reduction in weight entails much greater care in design and workmanship. The English Electric Company's " Wren," with 400 c.c. A.B.C. engine, flew extremely well at Lympne in 1923, and really, in spite of its almost ridiculously small engine, had quite a good power reserve. The machine was, structurally, an extraordinarily clever piece of work,
