دانلود کتاب Space, gravity and the flying saucer

THIS book is an attempt to introduce a theory of propulsion in space, other than by way of rocket, which has been suggested by the behaviour of the so-called flying saucer and supported by the author’s own observations over a number of years. Though the approach may be new, the theory involves no hypothesis with which we are unaccustomed. Rather, the arguments raised could present for debate yet another facet of a very old and familiar phenomenon.

The book is intended for both the interplanetary expert and the amateur enthusiast in this subject. The author, therefore, asks for patience from the more technically-minded reader, particularly where attempts have been made, by means of simple analogies, to clarify the more abstruse of his ideas. Some readers of this book may not believe in the existence of flying saucers. Even if flying saucers are not accepted, the author hopes that this book will suggest to believers and non-believers the possibility of a new and better way for earth-men to achieve their dreams of interplanetary flight. It may well be, even in our own time, that men will discover the key with which to unlock a force that is all about us and so enable us to use it for all our industries, transport, and, finally, space travel.
