NOVEMBER 6, 1924 TECHNICAL details of the machine are not available, but the photographs give a very good idea of the general lines. Built by the Bahnbedarf A.-G., of Darmstadt, the " BAG E.l " is a pure cantilever monoplane with plywood covered fuselage. It has the high aspect ratio wing so beloved by German designers, and the attachment to the fuselage is one of the most interesting features. It will be seen that the deck fairing is fairly narrow, so as to give a good view forward, and to the top of this fairing the wing spars are secured. The width over supports is very small, and it would appear that the attachment, unless it is very heavy, must be rela tively weak as regards resisting torque loads. The under carriage is of the type in which the axle projects through the sides of the fuselage and is enclosed in streamline fairings. * * * ANOTHER German light monoplane which has been doing a good deal of flying lately is the Caspar C.L.E. 17 with A.B.C. Scorpion " engine. This machine, designed by Herr Dipl. Ing. Ernst Ritter von Loessl and built by the Caspar Werke of Trawemiinde, is a low-wing cantilever monoplane two- seater, and one of the most interesting features is the flexibly- mounted wings. Springs are incorporated at the points where the wing spars attach to the wing roots, and it is stated that the machine is extremely steady in gusty weather. The top speed of the Caspar is about 115 km./h'. (72 m.p.h.). * * * LAST week we gave a brief account of the two light 'plane races at Dayton, of which one was won by the Driggs- Johnson monoplane and the other by the Mummert low-wing monoplane. In the race for the Rickenbacker Trophy, E. Dormoy's " Bath Tub " was first, with the Driggs-Johnson second. The Mummert forced-landed and retired. * * * THE Dormoy " Bath Tub " was designed by one of the designers at McCook, Field, Mr. Dormoy, and is, it will be seen, in some ways reminiscent of the BAT " Crow " designed and built by Mr. Fritz Koolhooven some years ago. It is a parasol monoplane with open tail girder, and in view of the number of struts and bracing, it is not surprising to lean, that the machine is somewhat slow. THE Mummert is a low-wing monoplane of fairly normal design, its most unusual feature being the wide-track under carriage, whose compression struts are attached to the wing some distance out from the fuselage. The chances of turning the machine over onto a wing tip should, therefore, be remote. * * * THE Driggs-Johnson is a parasol monoplane in which the space between the top of the fuselage and the undcrsurface of the wing is enclosed in a celluloid casing forming the upper portion of the pilot's cabin. The view is said to be par ticularly good, although most pilots would probably prefer to be seated out in the open. A <•> NEW " AVRO A. V. ROE AND Co., LTD., the pioneer aeroplane manu facturers, have purchased a large tract of land, approxi mately 163 acres, at Woodford, Cheshire, for a new aerodrome. The new aerodrome will, when completed, be one of the finest in the country, and its acquisition by A. V. Roe and Co., Ltd., undoubtedly marks another forward step in avia tion. Flying will commence in about two months' time, but it is expected that the aerodrome will not be really completed for about a year. The firm have just vacated the aerodrome at Alexandra Park, Manchester, which, whilst it has answered the purpose for a number of years, has certain disadvantages which will be absent in the one just acquired. In the first place atmo spheric conditions are considerably better at Woodford than in Manchester. Woodford is outside the smoke ring. It is situated between the Macclesfield hills and .Alderley Edge, and even when there is fog in Manchester and in Maccles field it is usually clear in Woodford. It will be recognised that this is a tremendous advantage from a flying point of view. Another point is the roominess of the new aerodrome. The area at Alexandra Park was approximately 88 acres, of which 33 were taken up by hangars and other smaller buildings, leaving a flying ground of 55 acres. Further, AERODROME this area is being rapidly closed in by buildings, another decided disadvantage. At Woodford there are 163 acres available, and the surrounding country is open. The three largest hangars and certain other equipment at Alexandra Park aerodrome have been purchased by A. V. Roe and Co., Ltd., and are being removed to Woodford. The removal of the hangars presents considerable difficulty owing to size. In each hangar there are 18 roof trusses, measuring 105 ft. in length and weighing between 3aand 4 tons. These 54 roof trusses have to be moved by road, and the problem of their transport has been solved by Mr. W. Kayley, who is employing a steam tractor and three trailers for the job. The future of the new aerodrome should be a very bright one. It will in all probability become the recognised aero drome for the area, and it is within the bounds of possibility that it may be used under the Air Ministry scheme for training of Reserve Pilots. It is interesting to note that the aero drome is well situated from the point of view of connecting up with the railway or for travelling to Manchester on alighting from a 'plane at Woodford. Stockport is only five miles from the aerodrome, Wilmslow two miles. Both are main line stations. Alternativelv a car will reach Manchester in about half an hour. • <$> <S> <C> vT Jitt^l^B J^R^PS1^^ V ••^ - v m 3 m* ^MkJLA MAJOR ZANNI'S WORLD FLIGHT : The above photograph shows Major Zanni's Fokker-Napier arriving at Hinandi, Iraq. The Argentine airman has got as far as Tokio, but owing to the lateness of the season he has decided to abandon the flight. Major Zanni has taken 19 flying days for his Amsterdam- Tokio flight—one day less than Pelletier d'Oisy's Paris-Tokio flight. The first 7,500 miles (Amsterdam- Hanoi) was accomplished in 17 flying days and with one Napier " Lion." Then the machine stuck in the mud and was crashed. The rest of the journey was completed on a new Fokker-Napier. Major Zanni, in a cable from Tokio, says :—" Very delighted state two Napier engines worked admirably until now without slightest indication trouble wear, and without any necessity change or touch parts." 709
