OTHING is more refreshing, when one has been submerged, as it were, in a set of problems along accepted lines, than suddenly to have sprung upon one an entirely new view-point opening up fresh fields for thought and con- templation. The paper read by Mr. G. H. Dowty before the Institution of Aeronautical Engineers on October 26 was in the nature of such a surprise, at any rate that part of his paper which dealt with whatBl Newng he termed " Arrester gears." When Ground one comes to think of it, it is rather amazing, as Dr. Thurston pointed out during the discussion, that although we have made great strides as regards aeroplanes in the air, when it comes to alighting we are very much where we. were in the earliest days of flying. One might even compare an aeroplane with a motor-car without brakes. Such a thing would appear quite ridiculous ; yet that is roughly the position as regards the aero- plane attempting to land, and this in spite of the fact that the aeroplane, with its relatively greater speed, would seem to be even more in need of braking devices than any other form of vehicle. Yet we have continued to rest content with relying upon the deceleration due to the air forces on the aeroplane, and to the—fairly small—frictional resistance due to undercarriage and tail skid. Wheel brakes have been tried, it is true, but not with any great success, mainly, probably, because if the retarding effect of the brakes is to be worth while, there is a good deal of risk of locking the wheels and standing the machine on its nose. Mr. Dowty's suggestion of an arrester gear, capable of pulling a machine up in something like 300 ft., no matter, within reason, what its speed, is therefore interesting, to say the least of it. We are aware, of course, that something of the sort has been tried in America with a certain amount of success, but we gather that during the first attempts, which were admittedly made with somewhat crude apparatus, the brake mechanism seized, the aeroplane
