In the meantime, without the use of balloons, the factory s workcontinued as best as it could; and in mid 1904 work had been carried out to try anddetermine the effectiveness of man-lifting kites. The idea was not new; in mid 1894 aman-lifting-kite-section had been added to the Balloon School using equipment whichhad been designed by Captain B F S Baden-Powell, but the stability of these kites wasnot adequate enough in gusty conditions and the experiments were new type of kites were designed by Samuel Franklin Cody and were of bi-planebox form and used a number of these varying size kites flown on a common proved considerably superior to previously tried systems and observers werelifted to over 1000 ft on many occasions with high levels of stability.

2 The primaryadvantage of the kite was that it could be used in wind conditions in which tetheredballoons were un-useable; and this capability made it an attractive proposition for theArmy. Cody worked hard with his kites and in April 1906 his diligence resulted in himbeing appointed the Chief Kite Instructor to the Factory in full time this next year or so, the Factory carried out a great amount of experimental andtraining work on spherical and elongated balloons, kites, aerial photography, signalingdevices and balloon winches. In this way it extended its scope to include theaccessories of aircraft as well as the aircraft 1906 J W Dunne had arrived at Farnborough to construct and test his tailless designaircraft the D1 biplane.

3 On completion it was taken to Blair Atholl in Scotland so thattests could be carried out in secrecy (see picture overleaf). Although it was originallyfitted with two 12hp Buchet engines, it was tested both under power and as a , like many of its contemporaries, it was heavily damaged on landing and,having been repaired and fitted with its engines, crashed again. Not an unusualoccurrence with these early attempts to KitesFAST is developing a series of briefingon key aspects of Farnborough sAviation briefing notes are not intendedto be a complete and comprehensivehistory of the subject of the title, but areintended to stimulate the imaginationand encourage further reading.

4 To thatend, a further reading list is included atthe end of each briefing. By reading anumber of different histories, written byvarying authors over a range oftimescales, a balance of the differencescan be achieved and the reader sown opinions formed. But we hope thatthese briefings will be an is a continuing process and a numberof further briefings are SERIES1-6 A Brief History of the FarnboroughAviation Site(1901 to 1991) The Early Days2. 1914-18 World War I3. 1918-39 The Inter War Years4. 1939-45 World War II5. 1945-90 The Cold War Period6. 1991 The Demise of Engineers Balloon School8. royal Flying Corps9.

Briefing No. 9 Page 2 of 7On 10 October, still moored at Crystal Palaceto avoid damage in high winds, she wasbuffeted so severely that some of the guy ropestore free. Hydrogen was released throughescape valves and a slit was made in theenvelope to speed up the process. Deflatedand partially dismantled, the remains weretaken back to Farnborough where they wereused in the manufacture of Nulli Secundus at the Factory, Cody was urging Capperto allow him to convert one of his kites to apower-driven machine.

7 The War Office wouldnot allow this approach, but consented for himto design the power train for Nulli Secundus -its similarity in design concept being seen in hisfirst aeroplane. In 1907, Cody modified one ofhis kites to be driven by the 12 hp Buchetengine and this was flown on a long wiresuspended between two 100 ft poles. Later itwas flown unmanned on Cove Common whichwas generally recognised as the first poweredflight at Farnborough (see Briefing No 12).Above : Nulli Secundus over Farnborough CommonNulli SecundusAbove : The Dunne D1 on the moors at Blair Atholl testing as a gliderIn September 1907 much of the experimental work of the Factory culminated in Nulli Secundus (Latin meaning second tonone ) - the first British Army Dirigible.

8 Nulli Secundus became Britain's first military aircraft when she flew on 10 September1907. She was built at the balloon factory at RAE Farnborough , and powered by a 50 hp (37 kW) Antoinette engine. On 5thOctober - piloted by Col. Capper, Lt Waterlow and Cody - she flew some 35 miles from Farnborough to London, averaging 16mph. She completed a tour over the city and, after circling St Paul's Cathedral, attempted to return to Farnborough , but 18mph (29 km/h) headwinds forced her to land at the Crystal Palace. Taking off at 11:00pm, the flight lasted for 3 hours and 25minutes and covered 50 miles (80 km) Science & Development at FarnboroughHistory and Learning BriefingsNo.

Briefing No. 9 Page 3 of 7In spite of these triumphs, dark clouds were ahead and in the spring of 1909, the War Office decided that the costs of this typeof flight - they had already funded all the aeroplane experiments to the tune of 2,500 - was excessive for the results Cody and Dunne were dismissed. Subsequently Dunne formed a company at Eastchurch and Cody moved to the otherend of Farnborough /Cove Common - South West of the Factory - to Laffans Plain.

10 With much perseverance and courage Codybuilt a number of aircraft (see Briefing No 12) winning many awards and competitions, but was killed in an aircraft accident the same spring of 1909 that had dispersed Dunne and Cody, the Secretary of State for War, R B Haldane, took twoimportant steps by forming the Advisory Committee for Aeronautics and making preparation for re-organisation of the BalloonFactory - which was chiefly meant for the production of Army dirigibles. Thus, in December of that year, this process causedthe separation of the Balloon Factory and the Balloon Section into manufacturers and users.
