А.Шепс Самолеты Первой мировой войны. Страны Антанты
Этой машине практически не пришлось принимать участие в боевых действиях, так как их поступление в дивизионы "Индепендент Эйр Форс" совпало с окончанием войны. Однако необходимо отметить конструктивные особенности машины, предназначавшейся для решения стратегических задач. Самолет создавался для нанесения бомбового удара по Берлину и другим важным объектам на территории Германии.
Создание подобной машины подстегнули участившиеся налеты германских бомбардировщиков "Гота", "Фридрихсгафен" и "Штаакен" на Лондон и другие города южной Англии.
Это был четырехместный двухмоторный биплан. Фюзеляж коробчатого прямоугольного сечения представлял собой деревянный каркас из стрингеров и шпангоутов, имел в носовой части обшивку из фанеры, а в задней части полотняную. Съемный гаргрот за кабиной пилота имел полотняную обшивку по реечному каркасу и крепился к фюзеляжу стальными лентами. В носовой части устанавливалась турельная установка и бомбовый прицел, причем впервые кабина бомбардира имела остекление. За ней располагалась кабина пилотов с двойным управлением, а затем, по задней кромке крыла, хвостовая турельная установка. Далее в нижней части фюзеляжа устанавливалась кинжальная пулеметная установка для обстрела нижней задней полусферы. Вооружение обеспечивало довольно надежную значительную защиту от истребителей противника.
Крыло двухлонжеронное. Нервюры имели ферменную конструкцию и усиление в местах крепления стоек. Элероны устанавливались на верхнем и нижнем крыле и имели деревянный каркас. Вся конструкция обшивалась полотном и покрывалась аэролаком. Оперение представляло из себя двухстоечную бипланную коробку с двумя рулевыми поверхностями. Конструкция была аналогична конструкции крыла. Стойки крыла и оперения имели трубчатую конструкцию и обтекатели из дерева. Над нижним крылом между стойками в шестигранных мотогондолах устанавливались два двигателя Роллс-Ройс "Игл-VIII" мощностью по 360 л. с. Это были 12-цилиндровые V-образные двигатели жидкостного охлаждения с лобовыми радиаторами, оборудованными регулирующими жалюзи. В мотогондоле располагались топливные баки и маслобак. Каждые шесть цилиндров имели отдельный выходной патрубок. Шасси имело жесткую конструкцию из металлических труб и четыре главных колеса, оборудованных шнуровой резиновой амортизацией. Под носовой частью устанавливалась противокапотажная лыжа, а в хвостовой части - костыль. Вооружение состояло из трех-пяти пулеметов 7,62-мм "Льюис" с комплектом до 500 патронов на ствол. Самолет мог нести более 1 т бомб на внешней подвеске под фюзеляжем и центропланом. Стандартная бомбовая нагрузка - 4 бомбы по 115 кг и 8 бомб по 56 кг.
"Вими" Mk I - первая серия машин с двигателями Роллс-Ройс "Игл-VIII" (360л. с.).
"Вими" Mk II - развитие серии Mk I, отличался более мощными двигателями Роллс-Ройс "Игл" (400 л. с.) с носовым колесом вместо противокапотажной лыжи. На вертикальном оперении появились два киля.
"Вими-Парашют-тренер" - машина на базе переделанного Mk I, оборудованная для обучения пилотов пользованию парашютом, было снято вооружение и установлена специальная лестница.
"Вими-Трансатлантик" - машина, оборудованная для перелета через Атлантику. Максимально облегченная, с закрытой кабиной и дополнительными топливными баками.
"Вими-Коммершл" - грузопассажирский самолет на базе Мк II с круглым фюзеляжем монококовой конструкции и уширенного сечения, оборудован пассажирской кабиной с окнами и дверью в левом борту.
"Вими" так и не совершил ни одного налета на Берлин, но свою известность он получил благодаря двум знаменитым перелетам, совершенным на нем.
14-15 июля 1919 года два пилота RAF капитан Джон Алкок и лейтенант Артур Виттен Браун совершили впервые перелет из Сент-Джона на о. Ньюфаундленд через Атлантический океан в Ирландию, совершив посадку у городка Клифден. В октябре-ноябре этого же года братья Росс и Кейт Смитт совершили многоэтапный перелет из Великобритании в Австралию, пролетев за 135 летных часов 18250 км со средней скоростью 120,7 км/ч.

C.Andrews Vickers Aircraft since 1908 (Putnam)
The E.F.B.8, which appeared in November 1915, powered by two Gnome monosoupapes, was smaller than its predecessor and carried only a single light Lewis gun, which could be accommodated equally well in single-engined types. This redesign was entrusted to Pierson, who stored the knowledge gained and revived it when a new twin-engined bomber was called for from Vickers by the Air Board in 1917, in the following circumstances.
Capt Peter D. Acland, at the time assistant manager in the Aviation Department of Vickers, gave the following account, in 1944, of the inception of the Vimy:
'The initiation of the design of the Vimy by Rex Pierson was the result of a conversation I had with Alec Ogilvie (Holding a position corresponding later to the Director of Technical Development) at the old Hotel Cecil in July 1917. At the time a large number of Hispano engines was surplus to fighter requirements for which they (the Air Board) were seeking a use. At that same time they were not getting sufficient Rolls-Royce Eagles to fulfil all their bombing requirements, and it was suggested to me that Vickers should attempt to build a bomber around the Hispano engine to the same specification as the Handley Page O/400.
'Pierson rapidly produced general layout designs, and an immediate order for prototypes was given. The first of these was flown by Gordon Bell at Joyce Green on 30 November, 1917. There was a different type of engine fitted into each of the other prototypes, including B.H.P., Fiat, Salmson and, subsequently, the Rolls-Royce Eagle.
'When the time came to place the production orders in April 1918, the Rolls was decided upon. History tells us the rest. The designing, building and flying of the machine in a period of four months was, to my mind, one of the highest spots of co-operative effort I have come across in many years in the industry.'
Pierson had related this story in a broadcast talk in 1942, when he said that with Maj J. C. Buchanan of the Air Board (later Air Ministry) he drew up the outline of the proposed Vickers bomber on a piece of foolscap paper in the Hotel Cecil, the Board's headquarters.
The four F.B.27 prototypes were fitted with 200 hp geared Hispano Suizas (later re-engined with 260 hp Salmsons), 260 hp Sunbeam Maoris, 300 hp Fiat A-12 and 360 hp Rolls-Royce Eagle VIIIs. These prototypes were conveniently referred to as Marks I to IV, but surviving Weybridge drawings do not confirm this early nomenclature, and official evidence on the subject seems to be conflicting. The Mark number system was never received with much enthusiasm on the production side until recent history, when it came to mean a lot more than merely airframe or engine modifications.
In the first F.B.27, called Vimy when the official naming of aircraft was introduced in 1918, the Hispanos were changed to Salmsons; the second, with Maoris, was lost soon after trials began because of engine failure; and the third, with the Fiats, also was lost by stalling on take-off at Martlesham and blowing up in the resulting crash as its bombs were armed (presumably for live practice over the nearby Orfordness armament and bombing ranges). The fourth Vimy prototype, with Eagles, went to Martlesham on 11 October, 1918, and confirmed the impression of exceptional performance for the period earned by the original F.B.27 in the previous January, also under test at Martlesham, the then newly established Aeroplane Experimental Establishment (Later renamed Aeroplane and Armament Experimental Establishment).
The original Vimy, with its geared Hispanos of dubious reliability, had lifted a greater load than the much larger and more powerful Handley Page O/400. The Eagle-powered Vimy prototype had a speed of 100 mph and endurance of 11 hours with full crew and a load of nearly 5,000 lb (including fuel) out of a take-off weight of 12,500 lb, a remarkable achievement in its day.
Behind the scenes in official quarters a controversy had raged between the protagonists of tactical and strategic bombing. This seems to have been resolved because of the need to retaliate against the night bombing of targets in Britain by German aeroplanes, which began in September 1917. In consequence, the Vimy was one of the new heavy bombers selected for production. The first contract, for 150, received by Vickers was on 26 March, 1918, and was followed shortly afterwards by another for 200, the first batch to be made at Vickers' Crayford works and the second at Weybridge. With contracts to other firms, the order book reached 1,130, with variations as to the specified power units. Production during 1918 was to be reserved for aircraft for anti-submarine duties (carrying two torpedoes) and subsequent deliveries for night-bombing aircraft.
The urgency of combating the U-boat menace with a more devastating weapon than the Blackburn Kangaroo, then operating, probably dictated the priority for anti-submarine work, but no Vimy was in fact ever used in that role.
In October 1918 one Vimy bomber was flown to Nancy, in northeast France, to stand by for a series of long-range raids deep into Germany, including Berlin. The Armistice of 11 November, 1918, cancelled this plan, and consequently the Vimy was not used operationally in the first world war.
Following the cessation of hostilities, the Government drastically reduced all orders for military aircraft, including those for Vimys, after Crayford had made seven and Weybridge six, but subsequently Weybridge made 99 Vimys for the peacetime Royal Air Force. Components already completed were purchased from certain of the former outside contractors, which aided production, and special aircraft were modified from the military versions to undertake long-distance pioneering flights. Indeed, the first aeroplane to make a trans-oceanic flight non-stop was the now famous Vimy crewed by Capt Jack Alcock (Among his colleagues in the pioneering days of pre-1914 Brooklands, Alcock was known as 'Jack') and Lt Arthur Whitten-Brown on 14-15 June, 1919, across the Atlantic.
The production Vimy followed the conventional design trends of its time, having a wire-braced biplane wing structure and stabiliser, also of biplane form, with twin fins and rudders. The front fuselage was of steel tube and the rear fuselage was of wood with steel end-fittings and swaged tie-rod bracing. The rear longerons were hollow spars to the McGruer patent, devised by a Clyde yacht designer and consisting of wrapped shims machined circumferentially from spruce logs. Recently examined by the inventor, the longerons on the transatlantic Vimy now in the Science Museum in London were found to be in perfect condition. Rudders and ailerons were aerodynamically balanced by extensions forward of the hinge points. The whole design was well proportioned, and upon this factor depended its success. Its Rolls-Royce engines were admirably suited to it, which was a new experience as far as Vickers were concerned, for their designers had suffered miserably from the allocation of unsuitable engines for previous aircraft, as has already been emphasised.
The use of Vickers' own wind tunnel at St Albans, the first commercially owned example anywhere, helped considerably in predicting aerodynamic performance and configuration, and Pierson cleverly exploited the reduction in scale from contemporary designs (as represented by the Handley Page O/400) to reduce structure weight. He also introduced refinements in detail design to achieve maximum strength factors.
Provision was made in the fuselage for part of the bomb load, the rest being carried under the bottom planes, with simple release gear. Two gunners could be carried, one in the nose with a Lewis on a Scarff ring, another similarly armed aft of the wings, with provision for shifting the gun to a pivot mount on the bottom of the fuselage for firing aft under the tail, with side windows for light when changing ammunition drums.
Maximum range was 1,880 miles, and the Vimy was easily capable of carrying what was for its time quite a respectable bomb load to Berlin. Various figures of speed have been quoted, from 98 mph to the 112 mph which Capt Broome, a Vickers pilot, was able to record on one test flight. Climb to 6,000 ft took 18 minutes, and the Vimy's ceiling, when fully loaded, was not more than 12,000 ft. Within this performance envelope, Alcock and Brown had to fly through the weather across the Atlantic. This led them into icing troubles and flying attitudes of the most unfamiliar character, in weather conditions which today's high-flying airliners can usually avoid.
The Ross and Keith Smith brothers' flight to Australia at the end of 1919 in a specially prepared Vimy proved the soundness of the design from another angle. It showed that the aeroplanes of the time could be operated across continents to far distant places and foreshadowed the day when scheduled services would be operated between Europe, the Far East and Australia, just as Alcock and Brown had presaged regular Atlantic air routes. The attempts to reach Cape Town by air by the Vimy of Van Ryneveld and Quintin Brand, and the other, sponsored by The Times and flown by Vickers' test pilots, Cockerell and Broome, did not experience complete success. But a far-reaching discovery had been made. Technical progress was needed to overcome the combined effect of high operating temperatures and greater altitudes on engine behaviour and performance, and on improvements in airframes, for wood and fabric and tropical conditions did not agree with one another.
Although the three pioneering flights undertaken by Vimys soon after the first world war have been fully documented, including a book (The Flight of Alcock and Brown, Graham Wallace (Putnam)) on Alcock and Brown's Atlantic conquest, the essential details are included here to keep the record complete.
For the Atlantic flight all the military equipment was removed from a standard Vimy (The 13th airframe off the post-war production line at Weybridge) and extra tankage installed in its place, thus increasing the fuel capacity from 516 to 865 gallons to give an optimum range of 2,440 miles. Actually, enough fuel for another 800 miles remained in the tanks after the flight had terminated in the Derrygimla bog at Clifden, County Galway, for the prevailing westerly wind had been of some assistance, as is normal in scheduled operations today. The engines were the standard Rolls-Royce Eagle VIIIs of 360 hp each, and they functioned reliably except for an occasional icing-up of the air intakes. In the twin-engined configuration it was possible for the crew to see the radiators and air intakes; with a single-engined tractor aeroplane this was not possible, and one theory now advanced for the failure of Hawker to complete the Atlantic flight on the Sopwith single-engined tractor machine was that his radiator shutters were partially closed through a control maladjustment, thus causing the engine temperature to rise. Had he been able to see his engine, this would not have occurred, and some weight is lent to this conjecture by the fact that the Sopwith also had the Rolls-Royce Eagle VIII engine, the type which did so well in the Vimy.
From take-off near St John's, Newfoundland, to landing in Ireland, the Vimy took 16 hr 27 min on the 1,890 mile non-stop flight, which included the night of 14 June. Visibility was too poor most of the time for the navigator to take sights and the weather anything but good for such an adventure virtually into the unknown. Their objective was Galway Bay, the conditions of the Daily Mail ?10,000 prize having specified 'anywhere in the British Isles' as the terminating point. Whitten-Brown, with his improved nautical methods of navigation, devised while he was a prisoner of war, crossed the Irish coast at Clifden, only a few miles north of his flight plan.
The Vimy was partially wrecked on landing in the bog; had the two airmen but known, the green pasture next to the one they had selected was quite solid, according to eye-witnesses at the time. The omission of the nosewheel in Newfoundland to reduce drag and weight was probably a sound idea, but that wheel might have saved the aircraft from nosing into the bog. The Vimy was rebuilt at Weybridge after recovery, and now is a treasured exhibit in the Science Museum in London, where one can engage in an interesting exercise in comparing it with modern aircraft, particularly with regard to its primitive navigational aids, and to its structure, now partially exposed to public view.
The next major event which was to concern the Vimy was the offer of a prize of ?A10,000 by the Australian Government for the first flight by Australians from Britain to Australia, to be completed within 30 days and before the end of the year 1919. Maxwell-Muller had engineered the Vimy at Weybridge for the Atlantic flight and prepared another for this fresh challenge. It was more or less of the standard military type with few changes apart from the provision of additional stores, to cope with tropical flying, in place of the normal military load.
The pilots chosen were the Smith brothers, Ross and Keith, of the Australian Air Force, as were the two mechanics, Sgts W. H. Shiers and J. M. Bennett. A considerable amount of pre-flight planning had to be done, petrol, oil and essential stores laid down at strategic points en route, and landing grounds carefully surveyed by agents in advance.
As far as Calcutta the air route was fairly well known, but eastwards from there the flight took on the form of trail blazing. The Vimy, valiantly flown and serviced by its Australian crew, won through, like Sir Francis Drake, 'after many vicissitudes', including vile weather, and reached Darwin from Hounslow in just under 28 days on 10 December, 1919, having covered 11,130 miles in 135 hr 55 min elapsed flying time. The aeroplane, G-EAOU, is now preserved in a memorial hall on the airport at Adelaide, home of the pilots, for the building of which the Australian public subscribed some ?A30,000.
The third great flight attempted by the Vimy was for a flight from England to Cape Town. Several efforts were made, but two Vimys achieved the greatest success. One was a standard military type, called the Silver Queen, flown by Lt-Col Pierre Van Ryneveld and Maj C. J. Quintin Brand of the South African Air Force. They left Brooklands on 4 February, 1920, but crashed at Korosko between Cairo and Khartoum a week later, a mishap caused by a leaking radiator. A second Vimy was loaned by the Royal Air Force in Egypt and named Silver Queen II. This one reached Bulawayo in Southern Rhodesia. There it failed to lift off from the high-altitude aerodrome in high temperature with a failing engine, caused by dirty oil, and was put out of action. The crew borrowed a D.H.9, completed the flight to Cape Town and were awarded ?5,000 each by the South African Government. They were knighted by King George V, as were the Smith brothers and Alcock and Brown, after their respective efforts.
Height and heat also defeated the other attempt by a Vimy, chartered from Vickers by The Times, with Dr Chalmers Mitchell as their Press representative on the flight. The aeroplane was the prototype Vimy Commercial G-EAAV (originally K-107). It left Brooklands on 24 January, 1920, and crashed at Tabora, Tanganyika, on 27 February, failing to takeoff in tropical conditions. It was found that the water in the cooling system of one of the engines was contaminated. It was clear that further engine and airframe development would be needed to operate in such conditions if the lessons of these African flights were to be fully applied. Judging from the successful use of the Vimy and its family successors in Egypt, the Middle East and India in later years, it seems clear that these troubles in African flying were taken to heart.
No. 58 Squadron RAF, in Egypt in July 1919, was the first to receive the Vimy bomber, as the Handley Page O/400 replacement, and operated the Vickers type until disbanded in February 1920. Subsequently, the type equipped other Middle East squadrons, and No. 216, with Vimys, ran some of the first mail services between Cairo and Baghdad. No. 7 Squadron at Bircham Newton was equipped with Vimys in June 1923, although 'D' Flight of 100 (the nucleus of 7 Squadron), had previously operated them at Spittlegate. Nos. 9 and 58 home-based Squadrons received Vimys in April 1924, on the re-forming of those units.
After replacement by the larger and more powerful Virginias in 1924 and 1925, the Vimy remained in service with 502 Squadron at Aldergrove, Northern Ireland, until 1929. Subsequent to their withdrawal from firstline service as standard heavy bombers, Vimys were re-engined with aircooled radials, either Bristol Jupiters or Armstrong Siddeley Jaguars, in place of the water-cooled Rolls-Royce Eagles. These were used in flying training schools such as No. 4 F.T.S. at Abu Sueir, Egypt, and for parachute training at Henlow. From Biggin Hill a night-flying unit equipped with Vimys operated long after the type had disappeared from the rest of the Royal Air Force; in fact, the Vimy was used right up to the time of the Munich crisis in 1938 as target aircraft for the searchlight crews of the Royal Engineers training at Blackdown, Hants.

O.Thetford Aircraft of the Royal Air Force since 1918 (Putnam)
The Vimy, together with the D.H. 10 Amiens and the Handley Page V/1500, was one of the new generation of bombers which, if the First World War had continued, would have been used by the R.A.F. for the bombing of Germany. However, the Vimy, unlike its contemporaries, enjoyed long service with the R.A.F. in the post-war years and until the introduction of the Virginia was the standard heavy bomber. Afterwards it served in various training roles until 1931.
The prototype Vimy (B 9952) made its initial flight in November 1917 with two 207-h.p. Hispano-Suizas and was followed by the Mk. II with 280-h.p. Sunbeam Maori engines, the Mk. III with 310-h.p. Fiat engines and the Mk. IV with 360-h.p. Rolls-Royce Eagle VIII engines. The Vimy IV became the standard production version and 240 were built, though many contracts were cancelled at the end of the First World War. The last of about 30 post-war Vimy IVs was the batch J 7701 7705 ordered by the Air Ministry in March 1925. On 31 October 1918 only three Vimy bombers had reached the R.A.K, and the type did not enter full service until July 1919, when it superseded O/400 bombers with No 58 Squadron in Egypt. It subsequently equipped other squadrons in Egypt and remained with No. 216 Squadron, operating some of the mail services between Cairo and Baghdad, until August 1926.
At home, Vimys of 'D' Flight of No. 100 Squadron at Spittlegate were the only twin-engined bombers in service until the formation of No. 7 Squadron at Bircham Newton in June 1923. No. 7's Vimys represented the R.A.F.'s entire home-based heavy bomber force until joined by Nos. 9 and 58 Squadrons in April 1924. In 1924 and 1925 the Vimy was replaced by the Virginia in first-line squadrons, but it remained on bomber duties with No. 502 Squadron in Northern Ireland until January 1929. From 1925 about 80 Vimys were re-engined with Jupiter or Jaguar radials (see three-view) and served at F.T.S.s and as parachute trainers at Henlow.
No account of the Vimy would be complete without reference to Alcock and Brown's epic Atlantic flight in 1919. This, however, was by a nonstandard Vimy owned by Vickers and cannot be credited to the R.A.F.

F.Manson British Bomber Since 1914 (Putnam)
Vickers F.B.27 Vimy
It is perhaps reasonable to speculate that, had a Vickers Vimy, flown by Alcock and Brown, not been the first aeroplane to fly non-stop across the Atlantic, the aircraft might have remained relatively obscure in the annals of the Royal Air Force; it was, after all, too late to give service during the First World War and, in the first half-dozen years of peace thereafter, it served on only five home-based squadrons.
Following hard on the heels of the decision to increase substantially the number of light bomber squadrons in the RFC, the Air Board opened discussions to investigate the possibility of introducing new heavy bombers into service with which to extend the offensive against German targets well beyond the Western Front. It has been told how large orders were quickly placed with Handley Page to hasten deliveries of the O/400, an excellent aeroplane, yet one that apart from the Eagle engines was already a long-established design.
The basic proposals for new heavy bombers were discussed at the Air Board's meeting of 28 July 1917 and, in response to the subsequent memorandum sent to Handley Page and Vickers, both companies embarked on new designs, three prototypes of each being ordered. The Vickers company was approached as it was known that its chief designer, Reginald Kirshaw Pierson, was already working on the preliminary design of a heavy bomber intended to meet the requirements set out in Air Board Specification A.3(B), issued in April, calling for an aircraft able to carry a 3,000 lb bomb load. In this he followed the general configuration of his previous F.B.7 and F.B.8 gun carriers (twin-engine biplanes), though of course the new bomber was to be much larger. The new requirements, in contrast to those of Specification A.3(B), placed less emphasis on bomb load and more on cruising speed and range, the former being reduced to around 2,200 lb and the latter increased to 90 mph and 400 miles respectively; an earlier demand for folding wings was also waived.
Reflecting the urgency attached to the new aircraft, the first Vickers F.B.27 prototype, B9952, was flown by Gordon Bell at Joyce Green on 30 November, only four months after the requirement had been first discussed, but made possible by use of the company's established steel construction.
Power was provided by two geared 200hp Hispano-Suiza engines and, with these, B9952 was delivered to the Aeroplane Experimental Station at Martlesham Heath in January 1918 where, despite some trouble with the engines, at an all-up weight (ballasted for a bomb load of 2,200 lb) it returned a sea-level maximum speed of 90 mph, thereby meeting the Specification's main requirements. This prototype featured horn-balanced ailerons on upper and lower wings, extending outboard of the square-tipped mainplane structure.
By then, however, all Hispano-Suiza engines were being allocated to production S.E.5A fighters, and the second Vickers prototype, B9953, was flown in April with a pair of 260hp Sunbeam Maori II engines, and delivered to Martlesham on the 25th. This aircraft featured inversely tapered ailerons, whose outer ends blended with the curved tips of the wings; it also introduced a ventral hatch through which a Lewis gun was mounted to fire, in addition to the upper gun positions in the nose and midships. B9953 was, however, to be destroyed in a crash in May.
At about this time the first aircraft was returned to Joyce Green, where the Hispano engines were replaced by a pair of 260hp Salmson 9Zm nine-cylinder water-cooled radials (though these engines never succeeded in producing more than about 230hp, and gave constant trouble with the cooling system).
The last o f the original Vimy prototypes, B9954, was fitted with 300hp Fiat A.12bis engines with octagonal frontal radiators, these having been scheduled to power the proposed 'Vimy Mark III' in production. Arriving at Martlesham on 15 August, this prototype demonstrated a maximum sea level speed of 98 mph while carrying 2,124 lb of bombs. This aircraft, however, was also destroyed when, on 11 September, it crashed on take-off for a bombing test from Martlesham and its bombs exploded.
Meanwhile an initial production order for 150 Vimys had been raised with Vickers Ltd for production at the cornpany's Crayford works, the engines being specified as the 230hp BHP, 400hp Fiat or the 400hp Liberty 12 - according to availability. In the event, only twelve of these aircraft were completed, and it is not known what engines were installed, although it is unlikely that any were fitted with Liberties as deliveries from America of these engines were temporarily halted in August.
With uncertainty surrounding the delivery of engines already flown in the Vimy, two further prototypes were ordered in August, it now being intended to fit 360hp Rolls-Royce Eagle VIII engines, whose production and delivery was assured. The first of these aircraft, F9569, arrived at Martlesham on 11 October for brief Service trials, returning a maximum speed of 103 mph at sea level. The aircraft was fitted with a single 452-gallon fuel tank in the fuselage bomb bay, sufficient for an endurance of about eleven hours while carrying two 520 lb bombs on external racks. This Vimy was then delivered to No 3 Aircraft Depot of the Independent Force in France, where it remained until after the Armistice. There is little doubt but that half-formed plans had existed for this aircraft to attempt a bombing raid on Berlin - involving a round flight of about 1.000 miles from the closest Independent Force aerodrome. Such a raid would have been marginally within F9569's capabilities.
The other new Vimy prototype, F9570, was destroyed by fire at Joyce Green before completion on 11 January 1919, but it is not known what engines were intended for this aircraft.
Production of the Vimy was severely reduced following the Armistice and, of the 776 then on order from Vickers and six other contractors, only 199 came to be built for the Royal Air Force, and contracted delivery dates were relaxed considerably owing to the postwar reductions in factory labour forces.
An order for 30 Fiat-powered Vimys (often referred to as Mark IIIs) was placed with the Royal Aircraft Establishment, but delivery of engines was erratic and only twenty aircraft were completed. As far as is known, only Eagle-powered aircraft were delivered to the RAF, and these became officially known as Mark IVs, simply to differentiate from the possible future use of the American Liberty engines in later aircraft (bearing in mind that many D.H.9As were to be powered by this powerplant). 150 Liberty-Vimys were ordered from Westland Aircraft Works, that company having been given the resposibility of designing the Liberty installation in the D.H.9A, but the superiority of the Eagle VIII in the Vimy caused this contract to be changed to the Rolls-Royce engine in the Westland-built Vimys, and the number of aircraft reduced to 25.
The first three production Mark IVs (one aircraft each from Vickers, Clayton & Shuttleworth and Morgan) were delivered in Februarv 1919. No homebased squadrons were yet scheduled to re-equip with Vimys and most of the early aircraft were shipped out to Egypt where they began to re-equip No 58 Squadron at Heliopolis in July that year, joining, and later replacing Handley Page O/400s.
Meanwhile, Vickers had begun the modifications to enable a Vimy to attempt an east-west non-stop crossing of the Atlantic, under conditions stipulated before the War for a prize of ?10,000 offered by the Daily Mail. The thirteenth aircraft in the production line at Vickers' new factory at Weybridge was modified to carry 865 gallons of fuel and all military equipment was omitted. The aircraft was shipped out to Newfoundland and, crewed by Capt John Alcock (later Sir John, KBE) and Lieut Arthur Whitten-Brown (later Sir Arthur, KBE) took off near St John's on 14 June 1919, landing 16 hours 12 minutes later near Clifden, Co Galway in Ireland, a distance flown of 1,890 miles.
The next long-distance Vimy was an aircraft prepared for the first aeroplane flight by Australians from Britain to Australia completed before the end of 1919, for which the Australian government was offering ?A 10,000. The flight was made by the two brothers, Capt Ross Smith and Lieut Keith Smith (later Sir Ross KBE and Sir Keith, KBE) of the Australian Air Force with crew members Sgts W H Shiers and J M Bennett. The flight was made between Hounslow, Middlesex, and Darwin, Australia, and took place between 12 November and 10 December, a distance of 11,294 miles being covered in 135hr 55min elapsed flying time.
The third of the great trail-blazing flights by Vimys was an attempt to fly from England to Cape Town by Lieut. Col Pierre Van Ryneveld (later Gen Sir Pierre, KBE, CB, DSO, MC) and Maj Christopher Joseph Quintin Brand (later Air-Vice Marshal Sir Christopher, KBE, DSO, MC, DFC, RAF). Setting off from Brooklands on 4 February 1920, their aircraft, however, crashed south of Cairo with a leaking radiator, and another attempt was made in a second Vimy, whose flight also ended prematurely, this time at Bulawayo in Southern Rhodesia. They completed their journey in a D.H.9, to be awarded ?5,000 each by the South African government.
At Heliopolis No 58 Squadron was renumbered No 70 in February 1920, this Squadron's role being that of bomber-transport, the Vimys being replaced by Vickers Vernon transports in November that year. The next Squadron to fly Vimys (including some of the aircraft just discarded by No 70) was No 45, reformed at Helwan as a bomber unit on 1 April 1921. This Squadron was tasked with route-proving flights throughout the Middle East in preparation for the introduction of commercial air travel in the region.
The first home-based Vimy Squadron to be equipped was No 100, newly returned from Ireland to become a day bomber squadron flying a mixed complement of D.H.9As and Vimys at Spittlegate (Grantham), and continuing in this role until May 1924 when it was re-equipped with Fairey Fawns.
The next Squadron to receive the Vimy was No 216, at the time regarded as the RAF's premier bomber squadron, having flown O/400s with great distinction during the War, and later equipped with D.H. 10s in Egypt. On receiving Vimys at Heliopolis in June 1922, the Squadron was declared a bomber-transport unit, dividing its efforts between practice bombing and carrying passengers (in some discomfort) and mail throughout the Middle East. No 216 Squadron continued to fly the Vimy until January 1926.
All the remaining four Vimy squadrons were home-based, No 7 re-forming at Bircham Newton in Norfolk with the aircraft on 1 June 1923, and continuing to fly them until April 1927. Most of the aircraft received on the Squadron from mid-1924 onwards were from a new production batch ordered in December 1923 (J7238-J7247). Nos 9 and 99 Squadrons, at Upavon and Netheravon respectively, began receiving Vimy IVs in April 1924, the former moving to Manston in the following month and the latter to Bircham Newton.
The last Squadron to receive Vimys was No 502 of the Special Reserve formed at Aldergrove on 15 May 1925, being declared a dedicated heavy bomber squadron and retaining these aircraft until July 1928.
Second-line duties performed by the Vimy included training, the type becoming the standard heavy bomber training aircraft during the early and mid-1920s. Many ex-squadron aircraft were converted with dual controls and issued to No 2 Flying Training School at Duxford and No 4 FTS in Egypt, and remained with these schools until the earlv 1930s. Others were used by the Parachute Training School at Henlow and by the Night Flying Flight at Biggin Hill. Many of these aircraft were re-engined late in their lives with air-cooled Bristol Jupiter and Armstrong Siddeley Jaguar radial engines when supplies of Eagle VIIIs became exhausted.

H.King Armament of British Aircraft (Putnam)
Vimy. That the armament of the Vimy twin-engined bomber (1917) was given high priority during development is suggested by the melancholy fact that the third prototype was blown up by its own bombs at Martlesham Heath. Several alternative loadings appear to have been possible. For the Fiat-engined aircraft, declared obsolete by an Air Ministry Order of 1921, the following stowages appear to have been planned: eight 250-lb + four 112-lb internal (bombs nose-up); two 520-lb under lower longerons; four 230-lb under lower centre-section. The most common variant had Eagle engines, and this appears to have had provision for twelve 112-lb or 250-lb bombs internally; eight 112-lb under lower centre-section; four 112-lb under fuselage; two 230-lb under lower longerons. A loading of eighteen 112-lb + two 230-lb has been recorded and consideration appears to have been given to the earning of two torpedoes.
The heaviest military' load quoted by the makers was 3.410 lb, and in this condition the Eagle-Vimy had a petrol capacity of 1.670 gal, giving a range of 550 miles at 6.000 ft. cruising at 90 mph. The military load instanced probably corresponded to a bomb load of twelve 250-lb. Four Lewis guns and ammunition would account for only about 130 lb. so the rest of the military load would presumably be made up of gun mountings, bombing gear, flares, etc.
Although a load of two 520-lb bombs has been recorded for the Fiat-powered Vimy, similar provision appears to have been made, in post-war years at least, on Eagle-powered aircraft. The sight fitted to production Vimys was the Drift Bomb Sight, High Altitude, Mk.IA, bracket-mounted on the nose. Some post-war Vimys used for training had a modified bomb-aimer's station, in a lengthened nose.
Standard defensive armament of production Vimys comprised a Scarff ring-mounting in the nose, carrying a single Lewis gun; a similar installation on top of the fuselage, roughly in line with the trailing edges (an accompanying photograph confirms twin guns in this position); and a third station in the floor, lit by side windows. A single rear gunner manned the two last-named stations. For the nose gun(s) a 4 1/2-in Neame No.1 illuminated sight was specified, together with four spare ammunition drums; for the ventral gun there was a 2-in Neame No.2 sight, and the two rear positions shared six spare drums between them. A contemporary account stated of the ventral gun:
'The gunner is able to fire through the bottom of the fuselage in a horizontal direction towards the rear. He can thus aim at a machine following at the same level without hitting the tail plane of his own machine.'
A notable experimental installation on one Vimy was made by the fixing of a trunnion-mounted 37-mm Coventry Ordnance Works gun to a pillar mounting, attached externally somewhat lo starboard on a specially modified nose section.

VICKERS "VIMY" TWIN-ENGINED BIPLANE.
The Vickers "Vimy" biplane was designed as a long-distance bomber, and, following the usual practice in twin-engined machines, has a single fuselage, carrying the pilot and two gunners, one in the nose and the other just aft of the trailing edge of the main planes.
The engines arc housed in " power eggs," each containing one complete power unit with its respective petrol and oil tanks, carried halfway bet ween the planes, one on either side of the fuselage.
Under each engine-housing is a separate under carriage consisting of two vees of steel tube, between which an axle and two wheels are slung on shock-absorbers.
To prevent the machine standing on its nose after too fast a landing, a skid is fitted under the nose of the fuselage.
Four large balanced ailerons are fitted to the main planes. The empennage consists of a biplane tail unit with two unbalanced elevators, and turn rudders with no fixed fin-area.
It was on a Rolls-Royce engined Vickers " Vimy" that Capt. John Alcock, D.S.C, and Lieut. Arthur Whitten Brown made the first direct flight across the Atlantic ocean.

A.Jackson British Civil Aircraft since 1919 vol.3 (Putnam)
Vickers F.B.27 Vimy and Vimy Commercial
The Vickers F.B.27 Vimy twin engined bomber of 1918 saw no war service but was the fastest weight lifter of its age. Designed by R. K. Pierson as a three bay, fabric-covered biplane of mixed construction, powered by two 360 h.p. Rolls-Royce Eagle VIIIs, it found employment in many peacetime Service roles and six became famous as civil aeroplanes. The first of these was the 13th Weybridge-built machine which was shipped to Newfoundland in April 1919 to be made ready for its historic Atlantic crossing. This was some weeks before civil flying was permitted officially and it was therefore too early to receive a registration. Piloted by Jack Alcock and Lt. Arthur Whitten Brown, it took-off from St. John’s, Newfoundland on 14 June 1919 with 865 gallons of petrol and 50 gallons of oil at an all-up weight of 13,300 lb. and touched down 1,890 miles away at Clifden, Ireland, 15 hr. 57 min. later, bogged and broken at the end of the world’s first transatlantic flight. After reconstruction at Weybridge it was presented to the Science Museum in London.
The first prototype Vimy, B9952, with 260 h.p. Salmson engines was allotted markings G-EAAR on 1 May 1919 but these were never carried and during its short career - a flight from Brooklands to Amsterdam in August 1919 for static display at the First Air Traffic Exhibition - wore the constructor’s number C-105. Active flying by the Vickers contingent was done by K-107, the Vimy Commercial prototype which had first flown at Joyce Green on 13 April and used the standard Vimy wing structure and tail unit mated to a rotund, oval section, plywood monocoque front fuselage seating 10 passengers. Entry was via a narrow opening in the port side, closed by a roller blind, and two pilots sat in an open cockpit high in the nose.
First flown on 20 September 1919, the next civil Vimy, G-EAOL, was a three seat bomber which left Brooklands in the following month for demonstration to the Spanish Government at Madrid. Although it disappeared into obscurity, its sister ship, G-EAOU, achieved immortality as winner of the Australian Government’s £10,000 prize for the first England-Australia flight. Piloted by Capts. Ross and Keith Smith and carrying Sgts. W. H. Shiers and J. M. Bennett as engineers, ’OU left Hounslow on 12 November 1919 and landed 11,340 miles away at Darwin, N.T., 27 days 21 hr. later on 10 December having averaged 75 m.p.h. for 350 flying hours, an incredible feat for those days and for which both pilots were knighted. After Sir Ross Smith’s 'death in the Viking IV accident at Brooklands (see page 206), the Vimy was stored for 35 years but in 1957 it was taken south from Canberra on two R.A.A.F. trailer vehicles for permanent exhibition in a glass memorial hall specially erected at Adelaide airport. Mainplanes, airscrews and cowlings were damaged by fire at Keith, 160 miles east of Adelaide while in transit on 3 November 1957 necessitating lengthy repairs which delayed final display for two years.
Inspired by the Australia flight, the Daily Mail put up a £10,000 prize for a flight from Cairo to the Cape for which three aircraft competed including Handley Page O/400 G-EAMC (Volume 2, page 226) and Vimy G-UABA ‘Silver Queen’ manned by Lt. Col. P. Van Ryneveld and Flt. Lt. C. J. Quintin Brand who left Brooklands on 4 February 1920 but crashed at Korosko in Upper Egypt. They continued in a borrowed R.A.F. Vimy named ‘Silver Queen II’ which crashed at Bulawayo.
After its success with the F.B.5 Gunbus replica (see page 351), the Vintage Aircraft and Flying Association built a Vimy replica, G-AWAU, powered by two Eagle VIIIs found in Holland, to commemorate the 50th anniversary of the first Atlantic flight. It was first flown at Wisley on 3 June 1969 by B.A.C. test pilot D. G. Addicott who flew it to the Paris Air Show a few days later. Repainted in R.A.F. colours as H651 it then went to Ringway for exhibition to Alcock and Brown’s fellow Mancunians but was seriously damaged by fire due to the heat of the sun on 16 July. After repair it was donated to the R.A.F. Museum, Hendon, bearing a different R.A.F. serial, F8614.

THE TRANSATLANTIC CONTEST
DURING the past week the principal development in connection with the Transatlantic contest has been the accession of the Vickers-Rolls-Royce machine to the list of entries. Details of this machine are given below, and two photographs are reproduced on the next page.
The four-engined Handley Page machine, with Rolls-Royce engines left Liverpool on May 2, and it is not expected that it will be ready to leave Newfoundland before the June full moon.
With a view to giving them a better chance of getting away in certain winds, Messrs. Hawker and Raynham have been searching the island for an auxiliary aerodrome, but so far they have not met with any success. The weather has been so unsettled as to prevent any attempt at the flight.
Dr. Alexander Robinson, the Postmaster-General there, has sealed a second mail and handed it to Mr. Raynham for conveyance across the Atlantic. The stamps are specially surcharged "First Transatlantic Aerial Mail" on the ordinary three-cents stamps. To prevent forgery each stamp is initialled by the Postmaster-General.
While preparing to start for Newfoundland on May 5, two of the United States flying-boats were damaged. Two wings of the N.C. 1 were completely destroyed, and the lower elevator and tail plane of the N.C. 4 were badly damaged. The fire was caused by a spark from an electrically-driven pump falling on a drum of petrol, which took fire. It is expected, however, that N.C. 2 will be sent to Newfoundland as soon as the weather permits. The N.C. type of boat has a span of 126 ft. The lower wing span is 94 ft. The wings are 12 ft. chord. The length of the hull is 44 ft. 9 ins. Its gasoline capacity is 1,890 gallons, contained in 10 separate tanks. Four 400 h.p. Liberty motors are fitted.
The Vickers "Vimy" - Rolls-Royce
THE following information concerning the "Vimy-Rolls" entered for the Transatlantic flight has come to hand, and should prove of considerable interest. - ED.
The construction of the Transatlantic "Vimy" has now been completed at the Weybridge aeroplane works of Messrs Vickers, Ltd. This aeroplane is practically similar in every respect to the standard "Vimy" as supplied to His Majesty's Government. Two standard 350 h.p. Rolls-Royce engines are installed. The capacity of the petrol tanks has been increased to 865 gallons, and the lubricating oil tanks to 50 gallons. With this quantity of fuel the machine has a range of 2,440 miles. The maximum speed is over 100 mile per hour, but, during the flight across the Atlantic the engines will be throttled down to an average cruising speed of 90 miles per hour. The span of the "Vimy" is 67 ft., and overall length 42 ft. 8 ins. The chord of the planes is 10 ft. 6ins. A wireless telegraphy set, capable of sending and receiving messages over long distances, will be carried, and the pilot and navigator will wear electrically heated clothing.
The pilot, Capt. J. Alcock, D.S.C., was born at Manchester in 1892, and received his technical engineering education at the Empress Motor Works, at Manchester. He became interested in aviation in its early days, and adopted it as a profession. He took the Royal Aero Club's Flying Certificate at Brooklands in 1912, and rapidly rose to the head of his profession, taking part in a large number of the early competition flights, amongst others the well-remembered race London to Manchester and return in 1913, in which he secured second place.
At the outbreak of War he immediately joined the R.N.A.S., and was posted to Eastchurch as an instructor. Later he became the Chief Instructor of the Aerobatic Squadron. He did valuable work on the Turkish front, where he won the D.S.C., and held the record for long-distance bombing raids. He was eventually taken prisoner by the Turks owing to an engine failure, and remained as such until the end of the War.
The navigator, Lieut. Arthur Whitten Brown, A.M.I.E.E. M.I.M.E., A.M.F A.I.E., who will be known to our readers as the author of a recent article in FLIGHT on elementary navigation, was born in Glasgow in 1886, and his parents were American citizens. He is an engineer by profession, and received his practical training with the British Westinghouse Co., which is now allied with the Vickers Co. He received a thorough knowledge of surveying, and being interested in aviation, naturally devoted study to aerial navigation as applied to surveying. He enlisted in the University and Public Schools Corps in 1914, later receiving a commission in the Manchester Regiment, and served with the 2nd Battalion in France during 1915. He then transferred to the Royal Flying Corps as an observer, and was wounded and taken prisoner of war in the same year. He was later interned in Switzerland, and repatriated in December, 1917, since which time he has been engaged with the Ministry of Munitions on the production of aero engines, and has put in a considerable amount of flying at home stations. He is also a pilot of some experience, and has flown many types of machines.
Lieut. Brown, after duration tests in the Transatlantic "Vimy," considers he will have no difficulty in making a successful Atlantic flight. He intends to rely upon a system of navigation similar to that employed in marine navigation, and will carry wireless instruments capable of receiving and despatching messages for a distance of 250 miles, and be able to communicate with passing vessels.
The preliminary nights were successfully carried out at Brooklands Aerodrome, Surrey, by these two officers, who expressed themselves completely satisfied with the tests. The Rolls-Royce engines ran perfectly, and the aeroplane left the ground with its load of four tons of petrol and oil after running a very short distance on the ground.
The aeroplane has now been dismantled and packed in cases. It is awaiting shipment to Newfoundland, and will be accompanied by the pilot, navigator, and mechanics, with their full equipment.

THE TRANSATLANTIC CONTEST
IN our issue of April 10 we published scale drawings of the Sopwith and Short Transatlantic machines. At the time no further drawings were available, and other machines have been entered since then. This week we are able, through the courtesy of the various constructors who have given us facilities for obtaining particulars of their machines, to place before our readers scale drawings of three other entrants and a photograph of a fourth, as well as scale drawings of one of the American flying-boats which will attempt the crossing hors de concours.
The Vickers "Vimy-Rolls"
A BRIEF description and two photographs of this machine were published in last week's issue of FLIGHT. The "Vimy-Rolls," as the Transatlantic type is called, is very similar in general arrangement to the standard "Vimy." Minor changes have naturally been made, but the general appearance is the same. Among the changes made the most important is the substitution of larger tanks, which now have a capacity of 850 gallons of petrol and 50 gallons of oil. A further alteration which has been made is the addition of a turtle back to the fore part of the fuselage, resulting in a cleaner outline with, presumably, smaller resistance. Two standard Rolls-Royce "Eagle" engines are fitted, which at full throttle give the machine a speed of over 100 m.p.h. The cruising speed is, however, in the neighbourhood of 90 m.p.h., and at this speed the machine has been estimated to have a range of 2,440 miles. Of other alterations reference may be made to the substitution, in the "Vimy-Rolls," of a front wheel mounted on a pyramid of steel tubes, instead of the front skid fitted on the standard "Vimy." The general arrangement drawings of the machine published herewith will give a good idea of the lines of the "Vimy-Rolls." As announced last week, the pilot is Capt. J. Alcock, D.S.C., who will be remembered by our readers from the days before the War, when he did a great amount of flying on a Maurice Farman biplane with Sunbeam engine. The navigator, Lieut. A. W. Brown, recently wrote a very interesting article for FLIGHT, dealing with elementary navigation for aircraft pilots.

THE VICKERS MACHINES
The F.B. 27 "Vimy." (Nov., 1917)
In June, 1917, Messrs. Vickers, Ltd., were invited by the Air Board to submit designs for a twin-engined night bombing machine. Having already had considerable experience with twin-engined machines, and the firm's designs being approved, the construction of F.B. 27 was immediately proceeded with. The first flight was made on November 30, 1917, by the late Captain Gordon Bell, who was then the firm's chief testing pilot, and who, after a few slight modifications, pronounced the machine satisfactory and highly promising.
In January, 1918, this machine was flown to Martlesham Heath, fitted with two 200 h.p. Hispano-Suiza engines, and, in spite of the low power, lifted about one-third of a ton more load than other much larger twin-engined machines fitted with the 300 h.p. Rolls-Royce engines. Needless to say, the test pilots at Martlesham Heath were very pleased with it on all points. During this time a second machine was constructed with two 260 h.p. Maori-Sunbeam engines, which slightly improved the climb. Very few tests were carried out owing to the machine being crashed, the cause of which was officially stated to be engine failure. A third machine was then fitted with Fiat engines. This machine was crashed shortly after arrival at Martlesham, owing to the pilot stalling shortly after leaving the ground. Unfortunately it had been loaded with live bombs, which exploded on reaching the ground, causing fatal injuries to the pilot.
An order was then received by Messrs. Vickers, Ltd., for 350 of these machines, and many large orders were also given to several firms, making a total of well over 1.000, the Air Board intimating that the machines delivered during 1918 were to be utilized for anti-submarine work, and that subsequent deliveries were earmarked for night bombing in France.
In October, 1918, the fourth experimental "Vimy" was sent to Martlesham Heath, fitted with two 400 h.p. Rolls-Royce engines, where it carried a load of 12,500 lbs. (nearly 6 tons) at a speed of 100 miles per hour, and an endurance of 11-12 hours; a remarkable performance for a machine of only 68 ft. span.
During the tests, instructions were received by the firm to send a pilot to Martlesham Heath to fly this machine to Nancy, whence it was the intention of the authorities to send it on very long bombing raids into the heart of Germany, including Berlin. However, the Armistice was signed before a suitable opportunity occurred, and the machine has been returned to Martlesham Heath for the continuation of the official tests.

The Conquest of the Atlantic
IT is with the profoundest satisfaction that we are able to record the fact that the first direct flight across the Atlantic has been accomplished by British aviators, flying a British machine, which is British in design and construction down to the last detail - not forgetting the engine. By their successful crossing of the wild Atlantic Capt. Alcock and Lieut. Brown have achieved a performance which will remain a landmark in history throughout the ages, and have placed to the credit of Britain and her sons a record second to none in the story of achievement by land, sea and air. For a parallel we have to go back to the days of the daring navigators of the Middle Ages, who ventured their lives in frail craft on the uncharted seas of the world, impelled by the thirst for discovery and by that subtle and indefinable desire to blaze out new trails which has created pioneers in every age.
In paying tribute to the wonderful performance of Alcock and Brown, we do not discount for a moment the almost equally glorious failure of Hawker and Grieve, or the more successful though less spectacular performance of Lieut.-Commander Read and his crew. Indeed, in so far as the latter is concerned, nothing can alter the fact that to America belongs the glory of having been first to throw an aerial bridge across the Atlantic. That her representatives succeeded as a result of meticulously careful organization and that the actual journey occupied more days than Alcock's did hours, does not for a moment alter the fact that to America belongs the credit of the first Atlantic flight. Still, it is the names of Alcock and Brown which will be for ever associated with the first direct crossing, and we scarcely think it is claiming too much to ask that they should be credited with the first real Atlantic flight. The two crossings are really not comparable at all, for reasons that must be perfectly apparent, and therefore need not be recapitulated.
The incomparable skill shown by the two companions of the flight is beyond all praise. It is apparent from their accounts of the crossing that the atmospheric conditions from start to finish could scarcely have been more unfavourable. Fog, rain, sleet and low-lying cloud's obscured their vision, so that only three times were they able to get observations of any kind, and only once, by climbing to 11,000 feet, did the sun become visible. Once they came down sheer from 4,000 feet to within 20 feet of the sea, and only by the exercise of superb airmanship, aided by marvellous presence of mind, was sudden disaster avoided. There are no words in the language which suffice to do justice to the combination of pluck, skill and judgment which in face of all these adverse circumstances brought the machine safely across to a point no more than 10 miles from its objective. It is more than unfortunate that the treachery of an Irish bog meadow led to a bad landing, and caused such damage to the machine as to make it impossible for the intrepid pair to set the final seal on their accomplishment by flying to London, as we believe was the intention. We most heartily congratulate Alcock and his skilful navigator on their brilliant success at the first time of asking, and at the same time we feel it is but fitting that we should express the feeling of profound satisfaction they have given their fellow-countrymen by thus at the same time placing to the credit of Britain the record of the first direct Atlantic crossing and the world's long-distance aerial record.
THE TRANSATLANTIC FLIGHT
WITH a British-designed and British-built aeroplane and engine, piloted by British officers, rests the honour of having made the first non-stop flight across the Atlantic. In an Editorial note on page 791 we have dealt with some phases of this magnificent achievement of Capt. J. Alcock and Lieut. A. Whittem Brown on their Vickers-Vimy-Rolls-Royce biplane, which has won for them the Daily Mail prize of L10,000, the 2,000 guineas from the Ardath Tobacco Co., and L1,000 from Mr. Lawrence R. Phillips for the first British subject to fly the Atlantic, and it only remains to record the material facts.
The news that the machine had definitely started on its voyage came in the form of the following message from Lieut. Clements, R.A.F., the official starter at Newfoundland :-
"Capt. Alcock and Lieut. Brown left St. John's, Newfoundland, in a Vickers-Vimy machine on a flight to England to-day, June 14, a t 4.13 p.m., Greenwich mean time."
Then followed a silence of a little over sixteen hours, ending by the following message from Capt. Alcock and Lieut. Brown to the Royal Aero Club, sent off from the wireless station at Clifden :-
"Landed Clifden, Ireland.fat 8.40 a.m., Greenwich mean time, June 15; Vickers-Vimy Atlantic machine, leaving Newfoundland Coast 4.28 p.m. (G.M.T.), June 14. Total time 16 hours 12 minutes. Instructions awaited."
The Royal Aero Club representative, Maj. R. H. Mayo, was in Dublin, but he immediately set out for Clifden, and by a friendly lift in an aeroplane and the aid of a motor car he got across Ireland in the quickest possible time. After an examination of the machine he wired the following message to the Royal Aero Club :-
"The official time of arrival in Ireland (crossing the coast) was 9.25 a.m., British summer time, actual landing time 9.40 a.m., B.S.T. I have examined the machine and found everything in order."
As soon as the formalities were completed Capt. Alcock and Lieut. Brown dismantled the instruments from their machine and prepared to make for London as quickly as possible. It was soon made clear to them, however, that Ireland wished to accord them a real welcome. They were given a civic reception at Galway, and all the way to Dublin on Monday afternoon they had ti most enthusiastic greeting. On arriving at Dublin it was intended that Capt. Alcock and Lieut. Brown should go to the Royal Irish Automobile Club, but the students of Trinity College carried Capt. Alcock into "commons" where there was much cheering with some speeches. Eventually the provost rescued the pilot and he and Lieut. Brown were able to go to the Automobile Club for dinner, afterwards proceeding to the Chief Secretary's Lodge where they spent the night as the guests of Mr. Macpherson.
Capt. Alcock and Lieut. Brown crossed to Holyhead on Tuesday morning, their progress from there to London being largely a repetition of the proceedings on the occasion of Mr. Hawker's homecoming. At Holyhead they were met by Mr. Pierson, the designer of the Vickers-Vimy, and by Capt. Vickers. There was a very large gathering to see them off, and at Chester, Crewe, and Rugby there were cheering crowds. At Crewe Mr. Claude Johnson, managing director of Messrs. Rolls-Royce, Ltd., joined the train and at Rugby Miss Kennedy, Lieut. Brown's fiancee, and her father, were waiting.
Profiting by their experience when Hawker came home, the authorities made arrangements to deal with a "big push" in London. At Euston the platform was crowded, so much so that Genl. Sir Capel Holden, the Vice-Chairman of the Royal Aero Club, was unable to get close enough to shake hands with Capt. Alcock.
Among others present on the platform were Maj.-Genl. E. D. Swinton, Col. S. G. Partridge, and Lieut. C. P. Robertson (of the Air Ministry), Brig.-Genl. R. M. Groves (Deputy Chief of the Air Staff, and representing Maj.-Genl. J. E. B. Seely), Sir Andrew Caird, K.B.E. (Vice-Chairman of the Associated Newspapers, Ltd.), Brig.-Genl. Sir Capel Holden, and members of the Committee of the Royal Aero Club, Sir Trevor Dawson, Sir Vincent Caillard, and Sir Francis Barker (representing Messrs. Vickers, Ltd.), and Mr. and Mrs. Hawker.
After some difficulty Capt. Alcock and Lieut. Brown made their way to the car of Col. McClean. Genl. Groves then handed to them, amid renewed cheering, messages from Genl. Seely (Under-Secretary of State for the Air Department) and Maj.-Genl. Sir Hugh Trenchard.
Genl. Seely wrote :-
"This letter, which is brought by Genl. Groves, is to convey to you, Capt. Alcock and Lieut. Brown, the most cordial congratulations on your splendid achievement, not only on my own, but also on behalf of the Air Council, the Air Ministry, and, I know, your comrades of the Royal Air Force. We rejoice that your skill and courage surmounted all difficulties, and enabled you to cross direct from one continent to another by air. I hope to meet you personally, and in the meantime I know that you will be glad to receive this letter at the hands of Genl. Groves."
Genl. Trenchard's notes to each officer ran :-
"On behalf of the Royal Air Force I wish to congratulate you on the first successful crossing of the Atlantic Ocean by air without a stop."
The car then led the procession to the Royal Aero Club, outside which a large number of people had gathered to give Capt. Alcock and Lieut. Brown a very hearty reception. They were welcomed by Gen. Holden, who said he did not think either of them appreciated as yet what they had done, and it would take them some time to do so. "They appreciate that we appreciate what they have done, but they do not appreciate themselves what they have done," he added. It was one of the most remarkable feats of this century, and one which would be remembered as long as the world lasted. It was nine years since Bleriot crossed the Channel, a distance of 20 miles. Everybody thought that a magnificent exploit at the time; but here they were welcoming men who had crossed nearly 2,000 miles.
Three cheers having been given for the airmen, there were repeated calls upon them to speak.
Capt. Alcock, standing on a chair, said :-
"I should like to thank Gen. Holden for the kind words he has said about Lieut. Brown and myself. I must say the flight has been quite straightforward. Although we had a little difficulty in keeping our course, Lieut. Brown did very well and steered a wonderful course. With regard to the flight itself all the credit is due to the machine, and particularly the engine - that is everything. If the engine went well there was nothing to prevent us getting across so long as Lieut. Brown was able to get his sights, and here we are."
Lieut. Brown, who also was loudly cheered, said :-
"Thank you very much indeed for your extremely kind welcome and for the kind words you have said about us. In a flight like this the essentials to success are, first, the design of the machine, for which our thanks are due to Messrs. Vickers and to the workmen who built it; second, the engines, the Rolls-Royce engines; third, the instruments with which the machine is equipped, and for these we have to thank the Air Ministry, who helped us to obtain the most modern apparatus which had been designed; and last, but not least, the pilot, Capt. Alcock. For with all these things the machine could not have made a successful flight without such a pilot as Capt. Alcock."
Afterwards Capt. Alcock and Lieut. Brown stepped out on to the balcony, where they were greeted with loud cheers by the crowds still waiting outside, Lieut. Brown ultimately driving off to Ealing where a further reception by the local authorities was gone through, whilst Capt. Alcock, after dinner at the Club went to Olympia to witness the great boxing match.
The following is the story of the crossing as given to the Daily Mail by Capt. Alcock :-
"WE have had a terrible journey.
The wonder is we are here at all. We scarcely saw the sun or the moon or the stars. For hours we saw none of them. The fog was very dense, and at times we had to descend to within 300 ft. of the sea.
For four hours the machine was covered in a sheet of ice carried by frozen sleet; at another time the fog was so dense that my speed indicator did not work, and for a few seconds it was very alarming.
We looped the loop, I do believe, and did a very steep spiral. We did some very comic "stunts," for I have had no sense of horizon.
The winds were favourable all the way: north-west and at times south-west. We said in Newfoundland we would do the trip in 6 hours, but we never thought we should. An hour and a half before we saw land we had no certain idea where we were, but we believed we were at Galway or thereabouts. Our delight in seeing Eashal Island and Turbot Island (5 miles west of Clifden) was great. People did not know who we were when we landed, and thought we were scouts on the look-out for the 'Vimy.'
We encountered no unforeseen conditions. We did not suffer from cold or exhaustion except when looking over the side; then the sleet chewed bits out of our faces. We drank coffee and ale and ate sandwiches and chocolate.
The flight has shown that the Atlantic flight is practicable, but I think it should be done not with an aeroplane or seaplane, but with a flying-boat. We had plenty of reserve fuel left, using only two-thirds of our supply.
The only thing that upset me was to see the machine at the end get damaged. From above, the bog looked like a lovely field, but the machine sank into it up to the axle and fell over on to her nose."
It certainly was unfortunate that what looked like a good meadow from above should have turned out to be a bog. Not only did the "Vimy" bury her nose in it but a R.A.F. machine which flew over from Oranmore to render assistance also came to grief. Later advices indicate that the Vickers machine is not so seriously injured as was at first supposed.
Although Capt. Alcock arrived in Ireland before anxiety had had time to develop some mystification was caused by the absence of any wireless messages. It appears, however, that the little airscrew driving the wireless generator blew off five minutes after leaving St. John's.
During the greater part of the flight of 1,950 miles the machine was at an average altitude of 4,000 ft. but at one time - about 6 a.m. - in an endeavour to get above the clouds and fog, it went up to 11,000 ft. Lieut. Brown was only able to take three readings for position, one from the sun, one from the moon and one from the Pole Star and Vega. On passing Signal Hill, Lieut. Brown set out a course for the ocean on 124 deg. compass course and at 3 a.m. from an observation on Polaris and Vega he found he was about 2 deg. south. He then set a course of 110 deg.
Between 4 and 5 a.m. the machine ran into a very thick fog bank, and the air speed indicator jammed, through sleet freezing on it, at 90 m.p.h. It was then that Capt. Alcock thinks the machine looped, at any rate it went into a steep spiral which only ended with the machine practically on its back about 50 ft. from the water. The machine was covered with ice, and it continually became necessary to chip ice off the instruments, etc.
Capt. Alcock says that he nursed the engines all the way, and had one-third of his petrol supply left when he landed One of the exhaust pipes blew off, but otherwise there was no trouble from the engine installation.
Apparently the start from St. John's provided an anxious time for the onlookers. The machine had a hard job to get away with her heavy load. The aerodrome level was only 500 yards long, but the machine took off at 300 yards, and just managed to clear the trees and houses. However she climbed steadily if very slowly, and when she passed over the harbour a t St. John's had reached a height of 1,000 ft.
Flight, August 21, 1919.
THE E.L.T.A. SHOW
THE AIRCRAFT EXHIBITION
The British Section
The greatest attraction on this stand is, undoubtedly, a Vickers Vimy with two Rolls-Royce engines, similar to the machine on which Capt. Sir John Alcock and Lieut. Sir A. W. Brown flew across the Atlantic in 16 hours. Used as they are to slow water transport, it is inevitable that a machine which has to its credit a sea voyage of such length accomplished in such incredibly short time should appeal to the Hollanders. Also in a sense they felt that the achievement was to a certain extent their own, as there is a Dutch branch of Vickers, Ltd., known as Nederlandsch-Engelsche-Technische Handel Maatschappij, with offices at Vickers House, Hague. The Vickers Vimy has already been described in FLIGHT, under Vickers "Milestones," to which we would refer readers for details.
Of other items on view on the Vickers stand mention may be made of a model of the "Vimy" standing inside a model Richards hangar, and of a larger scale model of a Vickers "Valentia" flying boat. In addition there are numerous samples of various kinds of Vickers high-speed steels, parts of a Wolseley "Viper" engine, and finally a number of excellent photographs. Out on the aerodrome is a Vickers Vimy-Commercial, to which reference will be made later.
Flight, November 6, 1919.
THE FLIGHT TO AUSTRALIA
In addition to the Sopwith "Wallaby" three other machines are now all but ready for the attempt, and are mainly waiting for an improvement in the weather before making a start. These are: A Martinsyde, an Alliance, and a Vickers-Vimy. As all the machines must start from Hounslow it would appear that the arrival of better weather will mean the start of all three machines more or less together, and an exciting race may therefore be looked to.
The Vicker's Machine
The machine entered by Messrs. Vickers, Ltd., is a standard Vickers-Vimy-Rolls bomber, which will be piloted by Capt. Ross Smith, M.C., D.F.C., A.F.C., and by his brother, Lieut. Keith Macpherson Smith. The machine is identical to those supplied to the Royal Air Force. It will be remembered that one of these machines was earmarked for the bombing of Berlin just previous to the Armistice. It is also similar to the machine used by Capt. Sir John Alcock, K.B.E., D.S.C., for his Transatlantic flight, except that for this flight a smaller petrol capacity is required. The engines used are the Rolls-Royce "Eagle," Mark VIII. The petrol is drawn from the main petrol tanks by two Vickers Mark II centrifugal petrol pumps, and delivered to the service tank, which forms a section of the top plane, from which it runs by gravity to the engines.
The maximum speed is over 100 m.p.h., but Capt. Ross Smith intends to throttle the engines down to a cruising speed of about 90 m.p.h. The weight of the machine empty is three tons; when carrying her full load on this flight, consisting of 4 men, 516 gallons of petrol, 40 gallons of oil and 10 gallons of water, together with spares, kit, tools and sundries (adding another 800 lbs.), the total weight fully loaded will be nearly 5 1/2 tons.
Capt. R. Smith and his brother, Lieut. K. M. Smith, were both born and educated at Adelaide, South Australia. At the outbreak of War, Capt. Ross Smith enlisted in the 3rd Australian Light Horse Regiment as a private, and sailed with the first Australian Expeditionary Force, landing in Egypt in December, 1914. After four months on Gallipoli he gained his commission, but later on contracted enteric fever and was invalided to England. He rejoined his regiment in March, 1916, was afterwards sent back to the Sinai Desert, and took part in the battle of Romani during the last Turkish attack on the Suez Canal in August, 1916. In October of the same year he joined the 6 ch (Australian) Squadron, Royal Flying Corps, as an observer, qualifying as a pilot in Egypt in July, 1917. He then rejoined his old squadron, now known as No. 1 Squadron, Australian Flying Corps, stationed in Southern Palestine, and remained there until the Armistice.
In December, 1918, he accompanied Air Vice-Marshal Sir W. G. H. Salmond, K.C.M.G., C.B., D.S.O., and Air Commodore A. E. Borton, C.M.G., D.S.O., A.F.C., on the first flight from Cairo to Calcutta, and after arriving at Calcutta, proceeded with Air Commodore A. E. Borton on his reconnaissance for aerodromes in Burma, Siam, Malay States and the Netherland East Indies. He returned to England about a month ago.
His brother, Lieut. Keith Macpherson Smith, R.A.F., will act as reserve pilot and observer. After leaving school, Lieut. K. M. Smith joined the staff of Messrs. Elder, Smith & Co., Ltd., of Adelaide, and on the outbreak of War offered his services for Overseas with the Australian Imperial Force, but was rejected. Several renewed attempts to enlist in 1915 and 1916 met with the same result, but subsequently he underwent an operation which considerably improved his health, and afterwards proceeded to England by the P. & O. steamship Medina, which was torpedoed and sunk in the English Channel during the voyage.
On arrival in England he joined the Royal Flying Corps as a cadet, shortly after becoming a pilot of unusual ability, and was serving as an instructor in the North of England until the Armistice.
Capt. Ross Smith and his brother will be accompanied by Sergt. J. W. Bennett, A.F.M., M.S.M., and Sergt. W. H. Shiers, A.F.M., who will act as engineers.
Sergt. W. H. Shiers was also born and educated at Adelaide, and spent his early life on a farm. Later on he went to Broken Hill, New South Wales, and worked at the North Mine as an electrical engineer. He was a student at the Technical College at Broken Hill, studying engineering and mechanics in his spare time, and seven years afterwards proceeded to Barren Jack Irrigation Scheme in New South Wales as an electrician for the Yanks-Leeton area in connection with Government contracts. In March, 1915, he enlisted in the 4th Divisional Artillery at Sydney, and was sent to Egypt, where he transferred to the 1st Australian Light Horse Regiment. He took part in the battle of Romani, and in October, 1916, was posted to the 67th (Australian) Squadron, Royal Flying Corps, as a mechanic. He rapidly gained promotion, and owing to his ability and resourcefulness he was on many occasions sent out in the Desert to bring in crashed or damaged machines, which was at times a most difficult and arduous task. He has handled almost every type of engine, and for the last 12 months of the War was working on Rolls-Royce engines.
Sergt. J. W. Bennett was born at St. Kilda, Melbourne, in 1892, and spent 14 years of his early life at Hawthorn, Melbourne, where he received a public school education, and attended night technical classes. He took great interest in all things connected with the early progress of the internal combustion engine, both for car and aviation use, received a thorough and early training with Salway motor engineers, and was employed for a considerable time with other prominent motor firms in Australia. At the outbreak of war in 1914, he was on the mechanical staff of Messrs. Denny Lascells, Motor Department, Melbourne, but enlisted in the Mechanical Transport, Australian Imperial Forces, sailing as a 1st Class Air Mechanic in No. 1 Squadron, Australian Flying Corps, with which he served in Egypt and Palestine until the Armistice.
On account of the excellent records of these two sergeants, they were specially selected to accompany Air Vice-Marshal Sir W. G. H. Salmond, K.C.M.G., C.B., D.S.O., Air Commodore A. E. Borton, C.M.G., D.S.O., A.F.C., and Capt. Ross Smith, M.C., D.F.C., A.F.C., on t he first Cairo to Calcutta flight, and Air Vice-Marshal Sir W. G. H. Salmond stated in India that the success of the flight was largely due to their skill and knowledge. They were subsequently awarded the Air Force medal for their work in connection with this flight, and accompanied Air Commodore A. E. Borton and Capt. Ross Smith on their reconnaissance for aerodromes in Burma, Siam, Malay States and Netherland East Indies. On returning to India, they both served with the North-West Frontier Forces in the late Afghan War.
