TUDOR PLANE'S SUCCESS.

BIG AVIATION ACHIEVEMENT (Special ( 'orrespondent.) Received Fridav, 7 p.m. LONDON, Alav 17. "An important occasion in history," ! was hpw Kt. Iloii. Joliu Wiliuot, Alinistor of Bupply, described Ihe Jirst. flight of Tudor Oue, carrying passengers. Tho l lirst British built airliner to be Jittyu with a pressure cabin for liigh altitude . Hying, tlie Tudor Oue reached 1 75,001) Ifeet in iifteen ttiinutes. At 2.7, 000 feet the pilot levelled olT and the pnssenget's breatlicd nornially without o.xygen mnsks and smoked if they desired. Thtpressur| inside the cabin at tliat hcight was equivalent to tl.viug conditions nornially found at S000 feet. The air in the cabin is takou in at intakes and leading edges of the wings so timi it is free of fiunos. Eaeh intake is protected froni ice and provided with a lilter to keep out dust wlien tlie aircraft is flying near the ground. The air is tlien passed to a blower on jhe engine ; and thcnce throngh a silencer and cooler i to a valve througli which it flows into tlie cabin. llere it is ducted to a lieater und.er tlie floor and the heated air is passed into tlie cabin througli mlets in the floor and in the sides of the seats, : and passes out througli tlie coiling. j Tudor Oue. which is designed for the i Xorth Atlautic service, will caify 21 : passengers in seats or twclve in bunks. j Tudor Two which will be used on j Empire routes, will be exactly the sanie ; niachine niechanically but will have a i larger fuselage and carrv less fuel and ! niore passengers. it is planned to carrv j 50 passengers just under 3000 miles and : 70 over a sliorter range. 1 The Tudor aircraft is claiined to be ! the most advanced of its tyye in tho . world and its pressure cabin is a not iable uchievenient. particularlv as 'Anui ! rican aeronautical exi>erts, wlio have | been experinienting with pressurisation, i have not yet been able to devise a i niethod whereby the aircraft c.an be ! takou higher t hau 20,000 feet withou; | the crew and passengers wearing j o.xygen nmsks. Afr. Wilinot declared 1 that pxporionco would prove tlie Tlidor I was the best pressurised airliner in tlie world. Twenty of these aircraft have been ordered by the C'overninent an-1 j will be out of the factory by .Tulv. By j the end of the yenr, .'10 Tudor Twos will I be delivered for Kinpiro routes. Britisli- aircraft const ructors are preparing a special ell'ort. tliis year 'to deinoust rate to the world tlie exceilenee of Britisli aviation niaterial, csppciully jet engines. The Society of Britisli Aircraft Const ructors is planning an aero show in Britain and Britisli aviation niaterials will be sliown at the fainous Paris Salon which is to reopen tliis vear. At Southainptou airport, tliere

will be an air display on .Tiiue 22, proceded by an aero exhibition froni June 15 to 21. The Paris show will be froni Xovomber 15 to Decenibor 1. .Tet engines will be sliown at botli places. Aiuorig tlie new Britisli units are some revolut ionarv designs giving Ijighei powers tlian anv other aero engines in production anv whare in Ihe world.
