Wire recordingWire recording, also known as magnetic wire recording, was the first magnetic recording technology, an analog type of audio storage. It recorded sound signals on a thin steel wire using varying levels of magnetization. The first crude magnetic recorder was invented in 1898 by Valdemar Poulsen. The first magnetic recorder to be made commercially available anywhere was the Telegraphone, manufactured by the American Telegraphone Company, Springfield, Massachusetts in 1903.
Aviation accidents and incidentsA Bombardier CRJ900, operating as Delta Connection Flight 4819, after it crashed upon landing at Toronto Pearson International Airport on February 17, 2025An aviation accident is an event during aircraft operation that results in serious injury, death, or significant destruction. An aviation incident is any operating event that compromises safety but does not escalate into an aviation accident. Preventing both accidents and incidents is the primary goal of aviation safety.
David Warren (inventor)David Ronald de Mey WarrenAO (20 March 1925 – 19 July 2010) was an Australian scientist, best known for inventing and developing the flight data recorder and cockpit voice recorder (also known as FDR, CVR and "the black box"). Early lifeDavid was born to Reverend Hubert and Ellie Warren and was one of four children. He was born on a remote mission station on Groote Eylandt in the Northern Territory, becoming the first white child born on the island.
AircraftAn aircraft or aerial vehicle is a vehicle that can fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, drones, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons.
Malaysia Airlines Flight 370Malaysia Airlines Flight 370 (MH370 / MAS370) was an international passenger flight from Kuala Lumpur International Airport in Malaysia to Beijing Capital International Airport in China. On 8 March 2014, the Boeing 777 operating on the route disappeared from radar with 227 passengers and 12 crew members on board. The cause of its disappearance has not been determined. It is widely regarded as the greatest mystery in aviation history.
International Civil Aviation OrganizationThe International Civil Aviation Organization (ICAO) is a specialized agency of the United Nations that coordinates the principles and techniques of international air navigation, and fosters the planning and development of international air transport to ensure safe and orderly growth. The ICAO headquarters are in the Quartier international de Montréal of Montreal, Quebec, Canada.
Safety orangeSafety orange (also known as blaze orange, vivid orange, OSHA orange, hunter orange, or Caltrans orange) is a hue used to set objects apart from their surroundings, particularly in complementary contrast to the azure color of the sky. (Azure is the complementary color of orange, and thus there is a stark contrast between the two colors.) The high-visibility color is commonly used in hunting contexts and for construction site safety.
G-forceThe g-force or gravitational force equivalent is a mass-specific force (force per unit mass), expressed in units of standard gravity (symbol g or g0, not to be confused with "g", the symbol for grams). It is used for sustained accelerations that cause a perception of weight. For example, an object at rest on Earth's surface is subject to 1 g, equaling the conventional value of gravitational acceleration on Earth, about 9.8 m/s2.
MisnomerA misnomer is a name that is incorrectly or unsuitably applied. Misnomers often arise because something was named long before its correct nature was known, or because an earlier form of something has been replaced by a later form to which the name no longer suitably applies. A misnomer may also be a word that is used incorrectly or misleadingly.European Organisation for Civil Aviation EquipmentThe European Organisation for Civil Aviation Equipment (EUROCAE) is an international organisation that deals exclusively with aviation standardisation, for both airborne and ground systems and equipment. It was created in 1963 in Lucerne, Switzerland by a decision of the European Civil Aviation Conference as a European forum focusing on electronic equipment for air transport. The organisation's offices are based in Saint-Denis, France near Paris.
United States Army Air ForcesAerial warfare branch from 1941 to 1947Military unitThe United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and de facto aerial warfare service branch of the United States during and immediately after World War II (1941–1947).*As an Amazon Associate I earn from qualifying purchases.
