BEARDMORE AIRCRAFT FOR ABROADTHE advance in aerial righting machines in the six years since the Great War is well reflected in the design of a batch of two-seater military biplanes, the order for which has been secured by William Beardmore and Co., Ltd., Glasgow, for a Con-tinental Government. Each machine has a top speed of 14S miles an hour, andcan climb to 16,000 ft. in 20 minutes with full load. Three machine-guns, of the latest Beardmore-Farquhar type arecarried, two for the pilot and one for the gunner, the latter carried on a special Scarff mounting, balanced to obviate theterrific force of the wind in the back seat. A special form of under carriage, patented by the builders and incorporatingspiral springs in compression in conjunction with Ferodo- faced damping plungers, is employed. Technically, the structure is of interest in that it will beexceptionally difficult to cripple by machine-gun fire. No bracing wires whatever are used in any part of the machine.All controls are operated by direct-acting rods or torsion tubes, and no cables running over pulleys are employed.The tail, a semi-cantilever structure employing only one bracing tube, is thus particularly clear of obstructions, soas to allow a complete field of fire in this direction. Finally, the petrol is carried m tanks in the top plane, employing asimple gravity feed which is not easily put out of action, or likely to go wrong. The engine is a Rolls-Royce Eagle IX. Designs have also been completed for a single-seaterfighter and a two-seater reconnaissance seaplane. The former is a strntbraced parasol monoplane, and is fitted with theBristol " Jupiter " Mark V engine, incorporating the new variable timing gear for obtaining increased performance ataltitudes. An undercarriage of an entirely new design is fitted giving a wheel track of 9 ft. 6 ins. The machine has avery high top speed and a remarkable rate of climb. The seaplane is a low wing monoplane with strut bracing tofloats and wings, and is fitted with a Rolls-Royce " Eagle " IX, engine. m m 58 m The Secretary of State for AirIT is reported that the Government has decided to raise the status of the Secretary of State for Air. Sir SamuelHoare, to rank equally with the Secretaries of State for War, India, the Colonies, and Foreign Affairs. Sir Sefton Brancker's Homeward Flight SIR SEFTON BRANCKER. Director of Civil Aviation, whois flying home from India in the D.H. 50 biplane (230 h.p. Siddeley " Puma ") piloted by Alan Cobham, flew fromDelhi to Karachi on February 18, covering the 800 miles in about nine hours. Brussels-Congo Flight LIEUT. THIF.FFRY, who, accompanied by his mechanic,de Bruycker, who is flying a 3-engined Handiey Page biplane from Brussels to Kinshasa, in the Belgian Congo, has suc-ceeded, with great difficulty, in crossing the Sahara, and has arrived safely at Gao, on the Niger. Paris-Dakar Flight CAPTAIN LEMAITRE and Capt. Arrarchard, the FrenchArmy airmen who flew from Paris to Dakar on a Breguet XIX.A.2 (480 h.p. Renault), have reached Timbuctoo fromBamako. U.S. Airship " Los Angeles " Flies to BermudaTHE U.S. Zeppelin airship " Los Angeles " (Z.R.3), which flew from Germany to America last October, madeanother big flight last week-end. The airship left Lakehurst at 3.45 p.m. on February 20 for Bermuda, carrying a con-signment of U.S. mails. Capt. Steele was in command, assisted by Capt. Klein, and in addition to the crew of 40,Mr. T. D. Robinson, assistant secretary of the Navy, and Rear-Admiral Moffett were on board as passengers. On theoutward journey rain and fog was encountered, and in spite of a head wind the airship made an average speed of 56 m.p.h.The 676 miles from Lakehurst to Hamilton, Bermuda, was covered in 12 hours, but heavy weather prevented the airsh'pbeing moored to the Patoka (the converted tank-steamer fitted with a mooring mast), which was stationed at Hamiltonfor the purpose. The mails were therefore dropped from the airship on to the lawn in front of Government House,and the " Los Angeles " turned homewards, after having cruised around for several hours. The return journey wassuccessfully accomplished, and the airship was safely moored at Lakehurst early in the morning of February 22. Anotherattempt to fly to Bermuda and moor there will be made this week. It is reported that the " Los Angeles '' willmake a flight to Europe (London) and back, with special mails, this summer. FEBRUARY 26, 1925 Experiments with Pilotless AeroplaneAN interesting demonstration will take place at Istres next month with a wireless-controlled aeroplane which willhave neither pilot nor passengers on board. Tests have already been made with this system of wireless control—the invention of M. Max Boucher—in which a pilot, after taking the machine oft the ground, did not touch the controlsagain until about to land. An Ulster Air ServiceIN addition to the Carlisle-Belfast air service shortly to be operated by Northern Air Lines, it is proposed to establishanother service linking up Londonderry with Belfast. City Air Force SquadronIT is almost certain that the headquarters oi the City of London Auxiliary Air Force Squadron (No. 60(1 City ofLondon (Bombing) Squadron) will be Finsbury Barracks. Incidentally, the City Territorial Association -which hasaccepted the responsibility of raising volunteer air unit.-,— will in future be known as the Territorial Association andAuxiliary Air Force Association for the County <>1 the City of London.
