In an essay written in the first part of 1914 by Captain H. C. L. Cock, R. A., published in The Journal of the Royal Artillery, we read:
No limit can well be placed to the ultimate development of airships and aeroplanes as new discoveries are made and applied to their construction. To look too far ahead, to anticipate problems which we may some day have to face, but which are not yet with us, is only to complicate an already sufficiently difficult question; and it may well be that by thinking too much of the possibilities of the future we may overlook some of the actual problems of the present. . . .
