| (2) E.W.Hives Esq continued More and more I note that the question of the Flying Machine and its importance as a weapon of War or as an adjunct to Commerce is forcing itself on the attention of the World and I am, as I always have been, pretty sure that the engine of the type I have invented is inevitably bound to supersede the present four-cycle type, more especially for working in the rarified atmosphere found at high altitudes. I can make it convenient at any time, now, to come up to DERBY but, in any case, I shall be glad of an early intimation of how the matter stands and if you have now completed your tests. Yours faithfully, E.M.Micklewood. | ||
