__NOTOC__
British Army Dirigible No 1, christened ''Nulli Secundus'' (Latin: "Second to none") was a Semi-rigid airship. First flown on 10 September 1907, it was Britain's first powered military aircraft. ==Design== Built at the Army's Balloon Factory at Farnborough, the early design work was carried out by Colonel James Templer, and it was completed by Colonel John Capper of the Royal Engineers and Samuel Cody, who was mainly responsible for developing the steering gear and power installation.〔 It had a cylindrical envelope constructed from goldbeater's skin without internal ballonets,〔Higham, Robin (1961) ''The British Rigid Airship, 1908-1931'' Henley-on-Thames: Foulis. p. 13.〕 from which a long triangular-section framework of steel tubing was suspended by four silk bands. The control surfaces, consisting of a rudder and elevators at the rear, a pair of large elevators amidships and a further pair at the front, were attached to this framework, and a small gondola containing the crew and power installation suspended beneath it. It was powered by a Antoinette engine driving a pair of two-bladed aluminium propellers via leather belts.〔(Airship Pioneers )''Flight'' 9 November 1916, p. 979.〕
