IS THIS THE LARGEST CARBURETTOR ? We show above a carburettor constructed by the well- known Zenith firm, at their factory in England, for a new 1,500 h.p. aero engine. Some idea of its size may be gathered from the 12-in. rule and the small motor- cycle type carburettor placed alongside. Madrid-Manila Flight THREE Spanish airmen, Capts. Rafael Martinez, EduardoGonzalez, and Joaquin Loriga, left Cuatro Vientos aerodrome, Madrid in three Breguet machines in an attempt to fly toManila. The Slotted Wing in Germany A NEW commercial aeroplane has just been completed by the famous German aircraft firm the Albatros Works of Berlin-Johannisthal in which leading edge slots and slotted ailerons are incorporated. The machine has been designed as a newspaper carrier and ordered by the well-known publishing firm Verlag Ullstein. Dr. Ing. Gustav Lachmann, who invented the slotted wing in Germany simultaneously with its invention by Mr. Handley Page in this country, has been mainly responsible for the design of the new Albatros machine, which is known as the type L. 72a, and is fitted with a 220-h.p. B.M.W. engine. Although carrying a wing loading of over 11 lb./sq. ft., the Albatros L 72a is claimed to land at about 47 m.p.h., so that the slotted wings seem to give a lift coefficient of about 1 in " absolute " units. The machine is a single-bay biplane of fairly large span, and is generally of very clean design. British to Welcome Commandante Franco IN connection with the arrangements made to welcome Commandante Franco upon his return to Spain after his wonderful exploit in flying to South America, two British representatives have left London for Madrid. They are taking with them messages to Commandante Franco, from Sir Samuel Hoare, the Secretary of State for Air, and the Royal Aero Club of Great Britain. In addition, they are conveying to Commandante Franco and the other participants in this epoch-making flight, presentations from D. Napier & Son, Ltd., the makers of the engines fitted to the " Plus Ultra." Mrs. Eliott-Lynn's Parachute Drop MRS. ELIOTT-LYNN, the energetic lady member of the London Aeroplane Club, made a successful parachute drop from an aeroplane at Hereford on April 3. When attempting this feat the day previous, the machine carrying her developed engine trouble just as she was about to jump, and had to make a forced landing, with Mrs. Eliott-Lynn still clinging to the side of the aeroplane. R.A.F.
