FLIGHT, JUNB 20, 1929 The fine range of Armstrong-Siddeley aero engines exhibited at the Canadian Aero Show in Montreal. An' Armstrong-Whitworth " Siskin " (Jaguar) with uncovered fuselage and wing, and the Genet-Avian were also shown. NON-STOP TO INDIA FLIGHT (Concluded from page 502.) The pilots had no practical alternative for avoiding the strong and persistent head winds from Baghdad to Karachi. They did test certain altitudes but without success, and were obliged to climb again. They could not afford to waste fuel in seeking other altitudes anyway. Meteorological experts told them afterwards that a more favourable passage prevailed below 2,000 ft., but you cannot fly safely down the Persian Gulf at that low altitude. They climbed at Cranwell with their engine running at 2,340 revolutions, which was gradually reduced throughout the flight until at Baghdad they were running at 2,180 revs. and 2,120 revs, at Karachi. They flew guided by prepared graphs, taking their weight every hour. Had the speed been maintained at the rate at which they reached Baghdad, calculations prove they would have reached the extreme south of India, where an aerodrome was actually prepared, and even Ceylon. The Fairey monoplane will be flown south, to Northolt or Martlesham, and be dismantled for the Olympia Aero Show in July. Afterwards it is probable that another attempt on the long distance record will be made with the same machine, although whether with the same pilots we do not know. It is the practice of the R.A.F. to share important flights amongst their best pilots. m m m m Auto Auctions, Ltd. AUTO AUCTIONS, LTD., who are the sole world distributors for the Blackburn " Bluebirds," are exhibiting one in their new showrooms at Burlington Gardens, Old Bond Street. It is the machine which Sqd.-Ldr. Ridley and Flight-Lieut. D'Arcy Greig will fly in the King's Cup Race, on July 5 and 6. Auto Auctions, Ltd., as previously stated, have taken one of the showrooms at Heston Aerodrome, where they will also give instruction on the "Bluebirds." .•-:- « <u sfe & IMPORTS AND EXPORTS AEROPLANES, airships, balloons and parts thereof (not shown separately before 1910.)
