FLIGHT, JOLY 22, 1932 CORRESPONDENCE J he Editor does not hold himself responsible for opinions expressed by correspondents. The names and addresses of the writers, not necessarily for publication, must in all cases accompany letters intended for insertion in these columns. ENGINE MOUNTING STRESSES [2797] Whilst I can readily follow Mr. Roger's explana tion of the method by which he has obtained the thrust and gravity components referred to in the issue of FLIGHT for July 1, I can see no justification for his assumptions (1) that the whole of the aft gravity component is carried at A and a, and (2) that the only thrust components carried by B and C are those due to a moment of the thrust load about a line A«. Norwich. J. F. Cuss. July 4, 1932. FAST FLIGHT FROM IRELAND [2798] I notice in your issue of July 1, under the head ing " From Heston," that a quick-time flight was made from Finglas to Heston in 2 hours 32 minutes. Whilst fully appreciating that this flight was accom plished in very good time, I should like to draw your attention to the three flights made by Hillman's Airways on Sunday last, June 26. The flights carried out were as under: — 1. Baldonnel to Heston, by Capt. E. D. Crundall, D.F.C., in " Puss Moth " G-ABSB. Time, 2 hours 30 minutes. 2. Finglas to Croydon, by Mr. T. W. Morton, in " Puss Moth " G-ABVX. Time, 2 hours 42 minutes. 8. Baldonnel to Stag Lane via Barton (where a landing was made), bv Mr. V. E. Flowerdav, in " Puss Moth " G-ABSO. Time, 3 hours. H. WOOD, Chief Pilot, Hillman's Airways. Romford Aerodrome, Essex. July 2, 1932. PUBLIC ATTENDANCE AT THE KING'S CUP [2799] I was much disappointed at the public attend ance for-the start of the King's Cup race this year. My wife and I were apparently the only two members of the general public who attended, and we were sorry to see such lack of enthusiasm, due, we feel, to the fact that the race was not enough advertised, Last year, at an earlier hour, there seemed to be much more attendance. Perhaps " the rabbits on the ground " are not out at dawn as formerly! Anyhow, " the public " had the pleasure of seeing the winner of the Siddeley Cup both start and finish, and sup ported their club. JOSE PEASE. Richmond, Yorks. July 15, 1932. * ft m m Aeromodellists' Rally at Shoreham A GRAND RALLY of Aeromodellists will be held on Shoreham Aerodrome on Sunday afternoon, July 24, at the invitation of the 9th Wing, the Model Aircraft Club (T.M.A.C). Air Mail Profits THE Postmaster-General, replying to questions in the House on July 4, stated that the profits on air mail ser vices in 1930-31 amounted to about £1,000, and that the charges for Imperial mails are fixed at so low a figure that the profits were quite inadequate to afford an indirect subsidy for the encouragement of new air lines. Savings on Air Expenditure THE Under Secretary of State for Air stated in the House on July 12 that the original recommendations of the May Committee covered specific savings on air expen diture (exclusive of research and inspection) of £299,000. The actual savings, partly permanent and partly non recurrent, ultimately effected under all heads of 1932 Air Estimates (including research and inspection) amounted to approximately £900,000. In addition, £50,000 was saved on expenditure on air services borne on the Colonial and Middle East Votes, making a grand total of £950,000 savings. R.A.F. Night Flying THE Under Secretary of State for Air was asked on July 12 what action he proposed to take about complaints of night flying in the neighbourhood of Hornchurch Aero drome. Sir Philip Sassoon replied that the night-flying exercises were essential if the defence of London was to be efficient, and the Air Minister felt justified in the public interests in asking for the forbearance of the community for the limited period of the exercises. High Masts in Somerset AIR MINISTRY Notice to Airmen (Special), Series A, No. 39, of 1932, is a notification that radio masts approxi mately 500 ft. high are being erected at Washford Cross, If miles S. by W. of Watchet, in North Somerset. Ignition of Holt Flares AN Air Ministry Notice to Ground Engineers, No. 26, of 1932, warns owners of aircraft and proprietors of civil aerodromes to ensure that the leads of Holt flares fitted to any aircraft should be disconnected before the aircraft are placed in a hangar. This notice has become necessary owing to the increasing use of night landing installations on private aircraft and owing to the possibility of accidental ignition of these flares.
