AUGUST 13, 1925 EGYPT-INDIA AIR SERVICE A PARLIAMENTARY White Paper was issued on July 28 by Sir Samuel Hoare, Secretary of State for Air, giving details of a supplementary estimate of ^10 (token vote) for the Air Service for the year ending March 31, 1926. The object of the vote is to obtain authority of Parliament for the establishment of a civil air transport service between Egypt, Iraq and India. In an explanatory note the Secretary of State for Air says: "I informed the House of Commons on June 11 that H.M. Government had approved in principle the institu- tion of a Civil Air Service between Egypt and India, and that it was their intention to grant a subsidy for this purpose. It is proposed to enter into a contract with a civil firm for a weekly air transport service between Kantara and Karachi, via Baghdad and Basra, to extend over a period of five years. In addition to the subsidy under this contract certain direct expenditure 'out of Air Votes will be involved for preparation of aerodromes, ground services, etc. " The total expenditure to be incurred out of Air Votes on capital services, maintenance and subsidy is estimated at an average of ^100,000 per annum over five years. " The institution of this service will, however, make it possible to terminate the fortnightly mail service at present performed by the Royal Air Force between Egypt and Iraq, and to withdraw in consequence from Iraq a squadron of the Royal Air Force, at a substantial net saving to the State (i.e., a reduction on gross Air Votes and a more than corresponding reduction on the Vote of Middle Eastern Services). In order that the saving referred to may accrue at the earliest possible date, it is desired to take steps to initiate the new service, i.e., to settle a contract and commence the necessary ground preparations. It is not anticipated that additional provision in respect of the subsidy will be required during the current financial year, but liabilities will be incurred on certain works services. " Any expenditure maturing this year will be accounted for under existing heads of charge. No excess on Air Votes generally is anticipated on this account, but, should it be necessary, Treasury authority will be sought under the terms of the Appropriation Act for the application of savings on other Air Votes to meet any excess occasioned on Air Vote 8. The terms of the subsidy agreement when concluded will be laid before Parliament in a White Paper." THE ROYAL AIR FORCE MEMORIAL FUND THE usual fortnightly meeting of the Grants Sub-Committee was held at Iddesleigh House on August 6. Lieut.-Commander H. E. Perrin was in the Chair, and the other members of the committee were :—Mr. W. S. Field, Squadron Leader E. B. Beauman. The committee considered in all eleven cases, and madegrants to the amount of ^63 10s. The next meeting was fixed for August 20. Some Fokker Type Corrections REFERENCE has been made in FLIGHT from time to time to the fact that with the Fokker welded-steel tube form of fuselage construction premature standardisation is avoided and changes in design are easily made. The result has been that the famous Dutch aircraft has been able in a short time to produce a large number of different types of machines. Special detachable engine mountings have also been stan- dardised, so that most of the Fokker types can be fitted with either of three or four different types of engine. From a practical point of view, all this is "naturally of great value, but to the journalist it is apt to present a stumbling block in that mistakes are easily made as regards types. Even FLIGHT has not altogether escaped such errors, and the Fokker firm has written to point out two which should certainly be corrected. In our article on Fokker construction in the July 16 issue of FLIGHT photographs were published of a machine which was described as a type C.VI, with B.M.W. engine. This should have read C.V. In the Fokker advertisement which appeared in last week's issue a photo- graph was given of a Fokker commercial monoplane withRo ifi?.™?££ine> while the text of the advertisement ' fo'-tKe achievement of a Fokker F.VII reaching La height of 19,000 ft. with a useful load of 1 ton. The com- bination might give the impression that this performance was attained with the machine shown in the photograph, while actually the F.VII in question was fitted with a Napier " Lion." We tender our apologies to all concerned, the error being due to the rush of producing a special issue. SOCIETY OF MODEL AERONAUTICAL ENGINEERS (London Aero-Models Association) THE attempt on the existing glider record of 53-4 sees, was held on the Sudbury ground on Saturday, July 25. Although this record was not beaten, a considerable amount of good flyinp was witnessed, the best duration being made by Mr. R. N. Bullock, with a glide of 42-6 sees., whilst Mr. F. de P. Green was a close second with 40-4 sees. The n^At competition is for the FLIGHT Cup, and will be held on Saturday, September 5, at Sudbury. For rules see FLIGHT of April 9. Attempts on hydro-aeroplane records will be held on the Welsh Harp, Hendon, on Saturday, September 19, at 3 o'clock. The Competition Secretary will be pleased to make arrange- ments of timing and judging any member's attempts on existing records if duly notified beforehand. A. E. JONES, Hon.
