Doubtless, there are many who believe that if we have not reached anything like finality in air craft design, we have, at any rate, come to the stage in development when further progress must necessarily be slow and chiefly in the nature of relatively small detail improvements. And for all that has been proved up to the present, that opinion may be correct. Some recent experi- The Rotor ments carried out in Germany—in a Aviation totally different direction—may, how ever, ultimately prove to be the innova tion, the radical change, which those who believe that we are unable to proceed much farther along the present lines have been hoping for. Herr Flettner's " rotor ship " has already made the shipping world " sit up and take notice," and if the rough estimates made by a correspondent, and published elsewhere in this issue of FLIGHT, are even very approximately correct, it may well be that before long the aviation world will be at least as interested. In fact, if the principles of Herr Flettner's invention are applicable to aviation, it would seem that the invention will mean even more to aviation than to shipping, for whereas in the case of the latter it can only mean an improvement, possibly a very great improvement, in the case of aviation it may mean the difference between a commercial proposition and—shall we say ? —a subsidised monopoly company ? Our correspondent, not being in possession of any " aerodynamical " data relating to the Flettner invention, has had to argue in a general way, and to some extent, therefore, the figures at which he arrives may easily be open to criticism. For all that, the speculations are of the very greatest interest, and it is difficult to see where any very great error can have been made. Our correspondent, who is, by the way, a well-known aircraft designer, has obtained the dimensions of the " rotor ship " from Lloyd's List, and starting with the total displacement of the " Buckau," he has estimated that the gross horse power necessary to drive the ship at the speed claimed to have been attained would be somewhere in the
