7 . / PERSONALS- 7 1 Obituary Lieut.-Col. OSWALD WATT was accidentally drowned, whilst surf-bathing, in Sydney Harbour on May 21 last. He obtained his pilot's certificate in 1911 on Salisbury Plain, "a*nd later did much flying in Egypt on a Bleriot. He joined the French Air Service when War broke out, and later trans- ferred to the Australian Flying Corps, in which he commanded a scouting squadron. With this squadron he distinguished himself in attackingthe enemy with machine guns at Cambrai in 1917. In recognition of his services with the Fiench he was awarded the Legion of Honour and the Croix de Guerre, To be Married The engagement is announced between Capt. CHARLES PHILIP OLDFIELD BARTLETT, D.S.C. and Bar, R.A.F., son of the Rev. C. O. and Mrs. Bartlett, of Minsterworth Vicarage, Glos., and JOAN AIKIN-SNEATH, daughter of Mr. F. Aikin- Sneath, J.P., and Mrs. Aikin-Sneath, of Tibberton Court, Glos. The engagement is announced between Capt. PHILIP BATEMAN, London Irish Rifles and R.A.F., son of the late Alfred George Bateman and Mrs. Bateman, of 7, Queen Anne Street and Feltham Court, Middlesex, and MARIE LOUISE BLANC, eldest daughter of Mme. IRHNE PROCOPIXJ, Lady-in-Waiting to H.M. the Queen of Rumania. Death of Professor Schoukovsky IT is reported that the well-known Professor Schoukov- sky has died at Moscow at the age of 74. His name will be most familiar to British readers from the deep-section, high- lift aerofoil which bears his name. This aerofoil gave some extraordinary results in the way of high lift, results which appeared quite fantastic until it was pointed out that they were obtained by fitting vertical baffle plates at the end of the wing so as to stop, or at any rate greatly reduce, end losses. Professor Schoukovsky first of all made hydrodynamics his speciality, and from this it was not a far step to aero- dynamics. In the latter branch of science he attacked and simplified the problem of the surface of infinite size, and he visualised a circular movement of the air around the aerofoil, which formed the basis upon which Prandtl, of the Gottingen laboratory, later built up his theory. In this country a similar theory was formulated by Lanchester. It is said that the Bolsheviks realised the eminent position held by Professor Schoukovsky, and allowed him to arrange special courses in aerodynamics. They are even stated to have gone so far as to allow him to draw increased food rations, which should probably be looked upon as a very great compliment to the famous scientist. Fatal Accident at Hamble A SA.D occurrence has to be recorded in the fatal accident Q.n the afternoon of April 25, at Hamble, Hants. The machine was privately owned by Mr. P. J. Pinckney, an Argentine ranch-owner, and was being piloted by Mr. T. L: Tebbitt, late R.A.F., from Lymington to Hamble, with Mr. Pinckney and his niece, Miss Frances Pinckney, they having in the morning flown from Croydon to Lymington. Appa- rently when landing the machine crashed, although at the subsequent inquest little light was thrown upon the cause of the mishap. The owner was killed instantly, and Pilot Tebbitt survived only a short time. Miss Pinckney, who sustained severe injuries to the legs and arms, is in hospital, and not likely to be able for some months to help to elucidate the cause of the accident. • American Ambulance 'Plane Comes to Grief ' FROM New York it is reported that a machine which had been converted into an ambulance, carrying pilot and si^ passengers, came to grief in West Virginia during a violent thunderstorm. The machine was returning from the air station at Langley Field, Hampton, Virginia, to Washington, when it encountered the storm which caused it to crash. Other machines which were in the air at the same time had the greatest difficulty in weathering the storm, and the famous pilot Rickenbacker, who was on his last stage of a flight across the Continent, had to make a forced landing on the side of a mountain. It is stated that the opinion has been expressed that the wrecked machine was probably somewhat heavily loaded, and that, in consequence, she was rendered less controllable, which fact, coupled with the extremely violent gusts, may have helped to bring about the accident which cost the lives of seven people, among whom was Col. Archie Miller, who commanded the United States Air Forces in France. JUNE 2,1921 The U.S. Navy Service "Messenger" Biplane THE Lawrence Sperry Aircraft Co., Inc., of Long Island, N.Y., write us as follows :—" It has been brought to our attention that through some mistake the impression has gone out that we were responsible for the design of the little Messenger machine, which has been described in articles in your paper as the Sperry Messenger. We wish to correct this impression by advising you that this machine was designed by the Engineering Division of the U.S. Air Service at M'cCook Field, Dayton, Ohio, and that the credit of the general design of this remarkable little machine is due to the McCook Field Organisation. We presume that in view of the fact that our plant was the one chosen to turn some of these machines out that the name Sperry was added to the description of this machine in the absence of the facts." In our description of this machine on February 17 last, FLIGHT made the position quite clear, as referred to above.] m m m m . .- PUBLICATIONS RECEIVED Les Moteursd'Aviation " Bristol."
