Beatrice Shilling Beatrice (Tilly) Shilling OBE PhD MSc CEng (8 March 1909 – 18 November 1990) was a British aeronautical engineer and motor racer. During the Second World War, she invented "Miss Shilling's orifice", a small metal disc similar to a metal washer that restricted fuel flow to the carburetor helping prevent engine stall in the Rolls-Royce Merlin engines of the Hawker Hurricane and Supermarine Spitfire fighters, which could lose power or even completely cut out during certain manoeuvres; a significant disadvantage in active service.

H2S (radar) H2S was the first airborne, ground scanning radar system. It was developed for the Royal Air Force's Bomber Command during World War II to identify targets on the ground for night and all-weather bombing, allowing attacks outside the range of the various radio navigation aids like Gee or Oboe, which were limited to about 500 km . It was also widely used as a general navigation system, allowing landmarks to be identified at long range.

Vickers machine gun The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The machine gun typically required a six to eight-man team to operate: one fired, one fed the ammunition, the rest helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft.

Hawker Tempest The Hawker Tempest is a British fighter aircraft primarily used by the Royal Air Force (RAF) in the Second World War. The Tempest, originally known as the "Typhoon II", was an improved derivative of the Hawker Typhoon, intended to address the Typhoon's unexpected fall-off of performance at high altitude by replacing its wing with a thinner laminar flow design. Having diverged considerably from the Typhoon, it was chosen to rename the aircraft "Tempest". The Tempest emerged as one of the most powerful fighters of World War II and was the fastest single-engine propeller-driven aircraft of the war at low altitude. The propeller-driven Dornier 335 was even faster, but it had two engines.

Zeppelin A Zeppelin was a type of rigid airship named after the German Count Ferdinand von Zeppelin (] ) who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874 and developed in detail in 1893. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word "zeppelin" came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I the German military made extensive use of Zeppelins as bombers and scouts, killing over 500 people in bombing raids in Britain.

Alcock Scout The Alcock Scout, a.k.a. A.1 and Sopwith Mouse, was a curious "one-off" experimental fighter biplane flown briefly during World War I. It was assembled by Flight Lieutenant John Alcock at Moudros, a Royal Naval Air Service base in the Aegean Sea. Alcock took the forward fuselage and lower wings of a Sopwith Triplane, the upper wings of a Sopwith Pup and the tailplane and elevators of a Sopwith Camel, and married them to a rear fuselage and vertical tail surface of original design (presumably by Alcock himself). It was powered by a 110 hp Clerget 9Z engine, and carried a .303 Vickers machine gun.

Bat bomb Bat bombs were an experimental World War II weapon developed by the United States. The bomb consisted of a bomb-shaped casing with over a thousand compartments, each containing a hibernating Mexican free-tailed bat with a small, timed incendiary bomb attached. Dropped from a bomber at dawn, the casings would deploy a parachute in mid-flight and open to release the bats, which would then roost in eaves and attics in a 20–40 mile radius. The incendiaries would start fires in inaccessible places in the largely wood and paper constructions of the Japanese cities that were the weapon's intended target.

Trimphone The Trimphone is a model of telephone designed in the 1960s in the UK. It was positioned as a more fashionable alternative to the standard telephones available from the GPO, the predecessor to British Telecom. The name is an acronym standing for Tone Ring Illuminator Model, referring to the then innovative electronic ringer ("warbling", as opposed to the traditional bell) and the illuminated dial. The luminous dial or betalight contained the mildly radioactive element tritium, which later caused some concern about safety. At one point during the 1990s the United Kingdom Atomic Energy Authority at Harwell was fined £5,000 by Wantage Magistrates Court for accumulating radioactive waste, having collected several thousand Trimphone luminous dials in a skip .

Enola Gay The Enola Gay ( ) is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction. "Enola Gay" participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in a secondary target, Nagasaki, being bombed instead.

Messerschmitt Me 262 The Messerschmitt Me 262, nicknamed Schwalbe (German: "Swallow") in fighter versions, or Sturmvogel (German: "Storm Bird") in fighter-bomber versions, was the world's first operational jet-powered fighter aircraft. Design work started before World War II began, but problems with engines, metallurgy and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944. The Me 262 was faster and more heavily armed than any Allied fighter, including the British jet-powered Gloster Meteor. One of the most advanced aviation designs in operational use during World War II, the Me 262's roles included light bomber, reconnaissance and experimental night fighter versions.

Operation Corona Operation "Corona" was a Royal Air Force (RAF) initiative to confuse German nightfighters during RAF bomber raids on German cities during World War II. Both native speakers and people who could speak German to a standard where they could be taken for a native speaker impersonated German Air Defence officers. They initiated communications via radio with German nightfighter pilots and countermanded previously given orders, thus reducing the efficiency of German air defence.

Biplane A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s.

Bristol Type 92 The Bristol Type 92, sometimes known as the Laboratory biplane, was an aircraft built by the Bristol Aeroplane Company to address the differences between wind tunnel cowling models and full scale cowling for radial engines and was designed as a scaled-up version of a wind tunnel model aircraft. One was built and flew in the mid-1920s.
