The Royal Aircraft Factory B.E.9 was a British experimental reconnaissance aircraft of World War I.
The intention of the designers was to combine the high performance of tractor configuration aircraft with a good field of fire for the observer's machine gun, as provided by pushers. It was therefore decided to modify an example of the B.E.2c by adding a small wooden box (which soon gained the nickname "pulpit") in front of the aircraft's propeller, which would accommodate a gunner armed with a Lewis gun on a trainable mount. The normal observer's cockpit of the B.E.2c was removed, allowing the engine (the standard air-cooled RAF 1a of the B.E.2) to be moved rearwards, while the wingspan was increased, and a larger fin was fitted. [1]
A general layout of this kind had various drawbacks - the most obvious being the perilous situation of the gunner - who was liable to injury by the propeller, or to be crushed by the engine in the mildest of crashes. The type was not developed further by the Royal Aircraft Factory (although the French SPAD S.A, of similar concept, saw service) and was soon rendered superfluous by the availability of synchronization gears.
The single prototype built (serial 1700) first flew at Farnborough on 14 August 1915. Early testing indicated that performance was little different from the B.E.2c upon which it was based, although the "difficulty" (surely an understatement) in communicating between the pilot and observer, separated by both engine and propeller, was reported. [2] and in September that year the B.E.9 was sent for testing in the field in France by a number of units, including No. 6 Squadron, 8 Squadron and 16 Squadron. [3] [4] While the B.E.9 carried out a few operational patrols in France, including one encounter with a German Fokker Eindekker, the opinion of those testing it was generally negative, with Major Hugh Dowding, at the time commander of 16 Squadron, stating that the B.E.9 was "...an extremely dangerous machine from the passenger's point of view", [5] while Hugh Trenchard, head of the RFC in France said that "this type of machine cannot be recommended". [6] It was sent back to the United Kingdom early in 1916. [5] In his memoirs, Lt Duncan Grinnell-Milne recalls his gratitude that initial combat experience with the type proved inconclusive and that it was not ordered into mass production. [7]

The Royal Aircraft Factory B.E.2 was a British single-engine tractor two-seat biplane designed and developed at the Royal Aircraft Factory. Most production aircraft were constructed under contract by various private companies, both established aircraft manufacturers and firms that had not previously built aircraft. Around 3,500 were manufactured in all.
The Airco DH.2 was a single-seat pusher biplane fighter aircraft which operated during the First World War. It was the second pusher design by aeronautical engineer Geoffrey de Havilland for Airco, based on his earlier DH.1 two-seater.
The SPAD S.VII was the first of a series of highly successful biplane fighter aircraft produced by Société Pour L'Aviation et ses Dérivés (SPAD) during the First World War. Like its successors, the S.VII was renowned as a sturdy and rugged aircraft with good climbing and diving characteristics. It was also a stable gun platform, although pilots used to the more manoeuvrable Nieuport fighters found it heavy on the controls. It was flown by a number of the famous aces, such as France's Georges Guynemer, Italy's Francesco Baracca and Australia's Alexander Pentland.
Between 1911 and 1914, the Royal Aircraft Factory used the F.E.2 designation for three quite different aircraft that shared only a common "Farman" pusher biplane layout.
The Royal Aircraft Factory R.E.8 was a British two-seat biplane reconnaissance and bomber aircraft of the First World War designed and produced at the Royal Aircraft Factory. It was also built under contract by Austin Motors, Daimler, Standard Motors, Siddeley-Deasy and the Coventry Ordnance Works.
The Royal Aircraft Factory S.E.5 is a British biplane fighter aircraft of the First World War. It was developed at the Royal Aircraft Factory by a team consisting of Henry Folland, John Kenworthy and Major Frank Goodden. It was one of the fastest aircraft of the war, while being both stable and relatively manoeuvrable. According to aviation author Robert Jackson, the S.E.5 was: "the nimble fighter that has since been described as the 'Spitfire of World War One'".
The Sopwith 1+1⁄2 Strutter was a British single- or two-seat multi-role biplane aircraft of the First World War. It was the first British two-seat tractor fighter and the first British aircraft to enter service with a synchronised machine gun. It was given the name 1+1⁄2 Strutter because of the long and short cabane struts that supported the top wing. The type was operated by both British air services and was in widespread but lackluster service with the French Aéronautique Militaire.
The Vickers F.B.5 was a British two-seat pusher military biplane of the First World War. Armed with a single .303 in (7.7 mm) Lewis gun operated by the observer in the front of the nacelle, it was the first aircraft purpose-built for air-to-air combat to see service, making it the world's first operational fighter aircraft.
The Armstrong Whitworth F.K.3 was a British two-seat general-purpose biplane built by Armstrong Whitworth Aircraft during the First World War. By the end of the war it was considered obsolete for combat.
The Armstrong Whitworth F.K.8 was a British two-seat general-purpose biplane built by Armstrong Whitworth during the First World War. The type served alongside the better known R.E.8 until the end of the war, at which point 694 F.K.8s remained on RAF charge.
The Royal Aircraft Factory B.E.12 was a British single-seat aeroplane of The First World War designed at the Royal Aircraft Factory. It was essentially a single-seat version of the B.E.2.
The Royal Aircraft Factory F.E.8 was a British single-seat fighter of the First World War designed at the Royal Aircraft Factory. It could not escape the drag penalty imposed by its tail structure and was no match for the Albatros fighters of late 1916.
The Nieuport 12 was a French sesquiplane reconnaissance, fighter aircraft and trainer used by France, Russia, Great Britain and the United States during World War I. Later production examples were built as trainers and served widely until the late 1920s.
The SPAD S.A was a French two-seat tractor biplane first flown in 1915. It was used by France and Russia in the early stages of the First World War in the fighter and reconnaissance roles. It was a unique aircraft that carried its observer in a nacelle ahead of both wing and engine.
The Royal Aircraft Factory B.E.8 was a British two-seat single-engined general purpose biplane of the First World War, designed by John Kenworthy at the Royal Aircraft Factory in 1913. Small numbers were used by the Royal Flying Corps over the Western Front in the first year of the war, with the type being used as a trainer until 1916.
The Royal Aircraft Factory R.E.7 was a British two-seat light bomber and reconnaissance biplane designed by the Royal Aircraft Factory and built under contracts by the Coventry Ordnance Works, Austin, Napier and Siddeley-Deasy for the Royal Flying Corps.
The Royal Aircraft Factory R.E.5 was a British two-seat reconnaissance and artillery observation biplane designed and built by the Royal Aircraft Factory for the Royal Flying Corps.
The Royal Aircraft Factory N.E.1 was a prototype British Night fighter of the First World War. A single-engined pusher biplane, it was a development of the Royal Aircraft Factory's earlier F.E.9 fighter, but was not successful, only six being built.
The Royal Aircraft Factory S.E.2 was an early British single-seat scout aircraft. Designed and built at the Royal Aircraft Factory in 1912–13 as the B.S.1, the prototype was rebuilt several times before serving with the Royal Flying Corps over the Western Front in the early months of the First World War.
The Royal Aircraft Factory C.E.1 was a prototype British flying boat of the First World War. It was a single-engined pusher configuration biplane intended to carry out coastal patrols to protect shipping against German U-boats, but only two were built, the only flying boats to be designed and built by the Royal Aircraft Factory.
