- JULY l6, I936. FLIGHT. 89 HERE and THERE A Woman Pilot's Altitude Record of 46,475 ft. : The Wakefield Models Contest : News of Forth coming Events The Potez sesquiplane in which Mile. Hilz (right) obtained her record. Maryse Hilz's 46,475 ft. Record SOME interesting additional information is now available regarding the two new altitude records, which, as reported in Flight recently, were established by Maryse Hilz, the French woman pilot, on June 23. Piloting a special Potez sesquiplane, with a Gnome-Rhone 14 Krsd. 900 h.p. twin-row radial, Mile. Hilz took off at 5.n a.m. from the Villacoublay aerodrome and climbed to 14,300 metres (46,475 ft.) in 36 min. , She thus broke the women's international record of 12,043 metres (39,140 ft.) made by the Italian aviatrice, Carina Negrone, on June 17, 1935, and also the French altitude figure of 13,061 metres (44,898 ft.) established on September 28, 1933, by the late Gustave Lemoine. Mile. Hilz carried a barograph of the new official F.A.I. type, which registers variations of temperature together with those of altitude and time. This instrument showed that the ascent took 36 min. and the descent 35 min. The lowest tem perature recorded was — 510 C, which was encountered at 10,000 metres (32,500 ft.). The temperature rose slightly above this altitude, and attained — 450 C. at 14,300 metres. No Qoggles Mile. Hilz wore a fur-lined suit, electrically heated, and an oxygen mask covered her nose and mouth. She did not wear goggles, as she feared that the moisture collecting on them would interfere with her vision. She declared on landing that everything went smoothly up to an altitude of 12,000 metres, out at this point .she began to experience sudden fatigue. As the machine climbed to 14,000 metres physical exertion became painful, her ears buzzed intensely and the fatigue threatened to overcome her will-power. ' The special altitude Potez is a variation of the type 50-A2, a military observation and day-bombing machine. The surface has been increased from 43 sq. metres (463 sq. ft.) to 57 sq. metres (614 sq. ft.), and the aspect ratio raised from 7.6 to 8.4. the upper wing span has also been increased by rather over 2 metres (6 ft. 6 in.). tracing wires and control cables were allowed a slight slack ness, so that their tension would not exceed the normal owing to the contraction due to a drop about 700 to 8o° C. in tem- perature. To avoid icing, leading edges and other parts were d with a mixture of oil and glycerine. The weight of he machine empty (including navigation instruments and per- Mumt fittings) is given as 1,470 kg. (3,234 lb.). the Onome-Rhonc supercharged 14 Krsd., tunning at 2,400 drove a three-bladed airscrew, geared 1:2. The corn-Press ii ratio was increased to 7.25: 1. R. C. W. In Other Spheres rTHE Yachting World (July 17)-deals fully with the inter national yacht racing during the Clyde Fortnight. Holiday touring and camping are excellently featured in The Motor Cycli (July 16) The Amateur Photographer (July 22) is a special Summer Open-Air N umber. To Try Again COMMENTING on the reports of structural defects in the wing of the Monospar Croydon, which last week-end re turned from Vienna, where it had landed in the course of an attempted record-breaking flight to Australia, General Air craft, Ltd., state that there was absolutely no evidence of such trouble. What did happen, it is stated, was that Lord Sempill, finding that the petrol feed from the auxiliary tank was not satisfactory, returned to Hanworth to have the defect remedied rather than undertake long "hops" under monsoon condi tions without the added safety afforded by the additional supply. It is proposed to make a fresh start, and everyone will wish Lord Sempill success. Death of Mr. John Carpmael CLIGHT regrets to record the death, on June 26, of Mr. •* John Carpmael, after a very short illness. Mr. Carpmael obtained his " A " licence at Hanworth on his seventeenth birthday. His sister and father were both learning to fly at the same time, and Mr. Carpmael, Sen., is a most enthusiastic Autogiro pilot. Mr. John Carpmael's ashes were scattered above Hanworth aerodrome last week by his instructor, Capt. Max Findlay. By Air to Tidworth Tattoo LAST year 48 visitors by air landed at High Post Aerodrome, Salisbury, to see the Southern Command Tattoo at Tid worth, twelve miles distant. This year the organisers hope to see still more, especially as High Post now has a hotel, where sleeping accommodation is available. The Tattoo Arena can be reached by bus or coach from the aerodrome. No night landing facilities are available, but a flare path can be laid for departures, provided notice is given. Intending visitors are asked to notify their requirements beforehand, if possible, to the Wiltshire School of Flying, Ltd., High Post Aerodrome, Middle Woodford, near Salisbury, Wiltshire. The Tattoo takes place on August 1, and from the 3rd to 8th. Seat reservations may be made at the Tattoo Box Office, Tidworth, or at the usual agencies.
