Bristol Standard Boxkite No. 12a.
The basic nature of aeroplane design is evident in this Bristol Boxkite. The first powered aeroplane flight had taken place in 1903 but in the absence of military interest (and therefore investment) development was slow and left to private venture. -

The other engine that did so much to advance the aeroplane's development was the 50hp Gnome rotary, seen here installed on Bristol Boxkite No 10 in May 1911, during demonstration flights in Australia.

A British-built "Bristol" biplane in flight on Salisbury Plain, piloted by Edmond. This machine was built entirely at their Filton works, near Bristol, by the British and Colonial Aeroplane Co., of which Sir George White, Bart., is a director. Needless to say, it has aroused considerable interest at the Company's flying school on Salisbury Plain, where Edmond has, we understand, been very successful in carrying passengers with it. This type of machine is now being turned out as rapidly as possible, and the Company's proficiency may be judged from the fact that the machine is seen in flight above the very first day it was erected.

The Bristol Boxkite
The Bristol biplane of 1910, familiarly but inaccurately dubbed 'the Boxkite', was an unashamed copy of the Henri Farman, using the same dimensions and scantlings, but introducing the more refined metal fittings, such as steel clips and cast aluminium strut sockets, of Zodiac practice. The quality of French-built Farmans was somewhat variable, but the Bristol biplane, though similar in general appearance, was equivalent to or better than the best that France had produced at that time. Indeed when the solicitors for Farman Freres proposed to sue the 'Bristol' Directors for infringement of patents, the Directors immediately entered a defence claiming substantial improvements, and no court proceedings ensued. The first two Boxkites were constructed at Filton to drawings made by George Challenger in June 1910, immediately after the abandonment of the Zodiac. They differed from all later Boxkites in having rear elevators with straight trailing edges and in having two, instead of one, intermediate vertical struts between each pair of upper and lower front booms. No. 7 was at first fitted with a 50 h.p. Gregoire four-cylinder engine and No.8 with a 50 h.p. eight-cylinder E.N.V., both being watercooled. A further point of difference was that No.8 had double-surfaced wings whereas No. 7 had a single fabric covering with pockets enclosing the ribs; the latter was standard Farman practice and was adopted on all later Bristol Boxkites, mainly to save weight. The Gregoire was unreliable and deficient in power, so Emile Stern's success in obtaining one of the first 50 h.p. Gnome rotaries released for export was particularly valuable. Fitted with this engine, No.7 was taken to Larkhill on 29 July 1910, assembled overnight, and flown the next day to a height of 150 ft. at the first attempt by Edmond, to the astonishment of beholders who had taken up prone positions on the ground in order to detect the first glimmer of daylight between the grass and the wheels.
With the efficiency of the design thus spectacularly confirmed, the two Boxkites were crated and dispatched to Lanark, where a six-day aviation meeting opened on 6 August at the race course. Only No.7 took part in any events, which Edmond completed without incident but with only one award, the second prize for the slowest lap, in which his speed was 45 m.p.h. Meanwhile, more Boxkites were laid down at Filton and Nos. 7 and 8 were allocated as initial equipment of the flying schools at Brooklands and Larkhill, respectively; No.8 retained the Lanark competition number 19 on its rudders for some months. As new aircraft were completed, the schools' complement was doubled, Larkhill receiving No. 9 in September and Brooklands No. 11 in November. Captain Dickson flew No.9 in the army autumn manceuvres in September and Lt. Loraine accompanied him on No.8, which had been equipped with a Thorne-Baker wireless transmitter. Nos. 10 and 12 were specially prepared for the Missions to Australia and India, respectively, the latter being the first to have upper wing extensions. The next two, Nos. 12A and 14 (No. 13 being unacceptable to any pilot of that date!) were flown from Durdham Down in the first public demonstration of the Company's activities; when these ended No. 12A was lent to Oscar Morison, who flew it in various demonstrations and competitions; No. 14 went on to Larkhill as a school aircraft, releasing No.9 for duty as the spare for the Indian Mission. Two further new Boxkites, Nos. 15 and 16, went to Brooklands, whence No. 11 was brought back for overhaul and packing as the spare for the Australian Mission. No. 16 was fitted with extended wings and a 60 h.p. E.N.V. water-cooled engine; the latter made it technically an 'All British' aeroplane for competition purposes, and thus it became the mount on which Howard Pixton, with Charles Briginshaw as mechanic, won the Manville Prize of ?500 for the highest aggregate time flown on nine specified days in 1911.
Both the Australian and Indian Missions arrived at their destinations in December, and on 6 January 1911 Jullerot demonstrated No. 12 before a Vice-regal party and a large crowd of spectators at the Calcutta Maidan. Invited to participate in the Deccan cavalry manceuvres, Jul1erot made several flights from Aurangabad, from 16 January onwards, carrying Capt. Sefton Brancker as army observer, and later took part in the Northern Manceuvres at Karghpur. Here conditions were very severe and both No. 12 and No.9 came to grief on the rock-strewn terrain, with a ground temperature of 100°F, but many flights were made and repairs kept pace with damage. When all the spares were used up, No. 9 was cannibalised to keep No. 12 flying and the latter survived to return to Larkhill as a school machine, being flown by many notable pupils, including Robert Smith-Barry, who was charged ?15 in October 1911 for repairs after a heavy landing on it.
In Australia, Hammond began flying on No. 10 at Perth late in December, going on to Melbourne, where 32 flights, many with passengers, were made. The Mission then moved to Sydney, whence Hammond went home to New Zealand leaving Macdonald as sole pilot. By 19 May 1911,72 flights totaling 765 miles had been completed without having had to replace a single bqlt or wire on No. 10. The spare machine, No. 11, still in its packing case, was sold to W. E. Hart, of Penrith, N.S.W., together with the unused spares, when the Mission left to return to England. Although this was the only direct sale made by both Missions, the Boxkite had by now begun to attract foreign buyers. The outcome of negotiations with the Russian Attache in Paris, William Rebikoff, was the first Government contract in the world for British aeroplanes, signed on 15 November 1910 for the supply of eight improved Boxkites having enlarged tanks and three rudders, which were called the Military model. The first three of these, Nos. 17, 18 and 19, were at first flown with 50 h.p. Gnomes, although 70 h.p. Gnomes had been specified for delivery in April 1911, when they were to become available. Meanwhile, No. 16, brought up to Military standard with three rudders but retaining its E.N.V. engine, was lent to Claude Grahame-White for an attempt to win the prize of ?4,000 offered by Baron de Forest for a flight from England to the most distant point along the Continental coast. No. 16 was damaged by a storm while waiting to take off from Swingate Downs, Dover, but was repaired in time for a second attempt on 18 December 1910, when Grahame-White was caught by a down-gust at the cliff-edge and crashed. No. 17, which was at Brooklands, was at once dispatched as a replacement, but caught fire soon after arrival at Dover, and Grahame-White then retired from the contest on his doctor's advice. Lt. Loraine had also entered the competition, flying No.8, but this too was badly damaged in the storm; No. 16 was eventually rebuilt and flown again at Brooklands. In April Nos. 18 and 19 were shipped to St. Petersburg together with Nos. 20 to 25 inclusive, after installation of 70 h.p. Gnome engines, but were later exchanged for two new machines, Nos. 26 and 30, in July 1911. No. 18 was damaged in transit back to Filton and written off, but No. 19 survived at Larkhill until May 1913, when it was dismantled and reconstructed as No. 134, which in turn was crashed at the Brooklands school in November 1913.
Still no contract came from the British War Office, and the next two Boxkites, Nos. 27 and 28, were standard school machines bought by the Belgian pilot Joseph Christiaens, who chose them for his flying displays in Malaya and South Africa. He took delivery of them on 19 January 1911, and after successful flights at Singapore on No. 27 went on to Cape Town and Pretoria, where he sold No. 28 to John Weston, who became the Company's agent in South Africa. A further school machine, No. 29, was sent to Brooklands in February 1911 and then two special exhibition models were built, having 70 h.p. Gnome engines, enclosed nacelles and increased span. The first, No. 31, was exhibited at Olympia in March 1911, and the second, No. 32, at St. Petersburg in April. The latter was inspected by the Czar and so impressed his military advisers that a gold medal and certificate of merit were awarded to the Company; and No. 32 was purchased in addition to the eight already ordered.
The War Office at last placed a contract, on 14 March 1911, for four Military Boxkites with 50 h.p. Gnomes as described in a specification submitted on 20 October 1910. Meanwhile Oscar Morison had damaged No. l2A while giving exhibition flights at Brighton, and No. 34 was taken from the production line to replace it. The first two War Office machines, Nos. 37 and 38, were delivered at Larkhill on 18 and 25 May, respectively, but then the War Office asked for the other two to be supplied with 60 h.p. Renault engines for comparison. This required a redesign of the engine mounting and carlingue, which resulted in a substantial nacelle structure in front of the pilot. No. 39, thus modified, was delivered at Larkhill on 9 July, by which time four more had been ordered, two with 50 h.p. Gnomes and two as spare airframes without engines. The latter (Nos. 40 and 41) were dispatched on 31 July, the second Renault machine (No. 42) on 2 August and the remaining Gnome machines (Nos. 48 and 49) during the subsequent fortnight. Nos. 43 and 47 were standard school Boxkites, the first being supplied to Larkhill while the second was taken to France by Versepuy when he returned in September 1911; he demonstrated it at Issy-les-Moulineaux and Vichy, where his mechanic was George Little; subsequently he sold it to the Bulgarian Government, to be flown by Lt. Loultchieff.
By this time the Boxkite production line had become well established and continued, mainly to supply wastage at the various schools, until 1914. In the standard models the wing extensions were retained but the third rudder was deleted. Strict interchangeability of components was maintained, and many later school machines incorporated serviceable parts from earlier aircraft. The 50 h.p. Gnome remained as the standard power unit except for No. 60 and No. 139, which had 70 h.p. Gnomes. The latter machine was supplied to R.N.A.S. Eastchurch in April 1913, receiving Naval serial no. 35, and was standard except for the engine, but No. 60 was similar to Nos. 31 and 32 with an enclosed nacelle, also incorporating longitudinal tanks and a push-pull handwheel control instead of the simple control-stick; this was demonstrated at Cuatros Vientos by Busteed in November 1911 and purchased soon afterwards by the Spanish Government, who ordered a similar spare airframe (No. 79) in which they fitted one of their own 70 h.p. Gnomes. Including rebuilds which received new sequence numbers, the total number of Boxkites built was 76, all at Filton except for the final six (Nos. 394-399), which were the first aeroplanes constructed at the Tramways Company's Brislington works. Although underpowered and out-dated at the end of their career, they survived mishandling often to the point of demolition, but the pupils emerged more or less unscathed and the mechanics performed daily miracles of reconstruction, so that school machines were constantly reappearing Phoenix-like from their own wreckage. Apart from the nine exported to Russia, three were sold to South Africa, two each to Australia, Germany and Spain, and one each to Bulgaria, India, Rumania and Sweden.
In addition to the Boxkite proper, there were two variants, both for competition work. The first of these was No. 44, which had wings of much reduced span and a small single-seat nacelle. This was for Maurice Tetard in the Circuit de l'Europe (racing no. 3) and was first flown on 30 May 1911; in the race it developed engine trouble and Tetard retired at Rheims, half-way through the first stage. The other was No. 69 and was a redesign in November 1911 by Gabriel Voisin using standard wings, but with the gap reduced and the front elevator and booms deleted; a single large tail plane and a single rudder replaced the normal biplane tail unit. It was sent to Larkhill for tests in February 1912. No photograph of this machine has survived and it was apparently soon rebuilt as a standard school Boxkite, in which form it was crashed at Larkhill by Major Forman on 3 November 1912.
