Women's Auxiliary Air Force
The Women's Auxiliary Air Force (WAAF), whose members were referred to as WAAFs (), was the female auxiliary of the British Royal Air Force during the World War II, Second World War. Established in 1939, WAAF numbers exceeded 181,000 at its peak strength in 1943, (15.7% of the RAF) with over 2,000 women enlisting per week. History A Women's Royal Air Force (World War I), Women's Royal Air Force had existed from 1918 to 1920 but had been disbanded in the wake of the end of the World War I, First World War, alongside the Queen Mary's Army Auxiliary Corps, Women's Army Auxiliary Corp (1917–1921) and the first iteration of the Women's Royal Naval Service (1917–1919). Second World War The Women's Auxiliary Air Force was created on 28 June 1939, absorbing the forty-eight RAF companies of the Auxiliary Territorial Service which had existed since 1938, following the Munich Agreement. Conscription of women did not begin until after December 1941 when the UK Government passed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plotter (RAF)
Plotters were employed on an early form of air traffic monitoring that played a vital role in World War II, including during the Battle of Britain, The Blitz and the bombing of British cities that followed. They worked at individual RAF stations' Sector Control Rooms or in the central Group Control Rooms that directed the operations of RAF fighters. The majority of plotters were female, members of the Women's Auxiliary Air Force (WAAFs). History Captain Philip Edward Broadley Fooks transferred from the Royal Garrison Artillery to the Anti-Aircraft Defences, Home Forces in June 1918 and he suggested displaying the latest information graphically on a large horizontal map at central London control near Horse Guards in Spring Gardens. This map was marked with a grid upon which different-shaped and annotated pieces representing the airborne forces were colour coded to the clocks to distinguish fresh from older information and were manipulated with wooden rakes by operators guided by ...

Intelligence (information Gathering)
Intelligence assessment, is a specific phase of the intelligence cycle which oversees the development of behavior forecasts or recommended courses of action to the leadership of an organization, based on wide ranges of available overt and covert intelligence (also known as "intel"). There are two types of assessment; * In the beginning of the intelligence cycle, during the direction phase (also known as tasking or planning), intelligence officers assess past intelligence, identify gaps in information, and determine what new intelligence is needed. * Intelligence assessment also occurs toward the end of the intelligence cycle, during the analysis & production phase. This phase comes after collection and processing but before dissemination to policymakers. Assessments develop in response to leadership declaration requirements to inform decision-making. Assessment may be executed on behalf of a state, military or commercial organisation with ranges of information sources availa ...

Photo Reconnaissance
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers. History Early developments After the French Revolution, the new rulers became interested in using the balloon to observe enemy manoeuvres and appointed scientist Charles Coutelle to conduct studies using the balloon ''L'Entreprenant'', the first military reconnaissance aircraft. The balloon found its first use in the 1794 conflict with Austria, where in the Battle of Fleurus they gathered information. Moreover, the presence of the balloon had a demoralizing effect on the Austrian troops, which improved the likelihood of victory for the French troops. To operate such balloons, a new unit of the French military, the French Aerostatic Corps, was established; this organisation ...

Codes
In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example is an invention of language, which enabled a person, through speech, to communicate what they thought, saw, heard, or felt to others. But speech limits the range of communication to the distance a voice can carry and limits the audience to those present when the speech is uttered. The invention of writing, which converted spoken language into visual symbols, extended the range of communication across space and time. The process of encoding converts information from a source into symbols for communication or storage. Decoding is the reverse process, converting code symbols back into a form that the recipient understands, such as English, Spanish, etc. One reason for coding is to enab ...

Telegraph
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined, so such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the Chappe telegraph, an optical telegraph invented by Claude Chappe in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephony
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunications services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs: each user had a separate telephone wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorology
Meteorology is the scientific study of the Earth's atmosphere and short-term atmospheric phenomena (i.e. weather), with a focus on weather forecasting. It has applications in the military, aviation, energy production, transport, agriculture, construction, weather warnings and disaster management. Along with climatology, atmospheric physics and atmospheric chemistry, meteorology forms the broader field of the atmospheric sciences. The interactions between Earth's atmosphere and its oceans (notably El Niño and La Niña) are studied in the interdisciplinary field of hydrometeorology. Other interdisciplinary areas include biometeorology, space weather and planetary meteorology. Marine weather forecasting relates meteorology to maritime and coastal safety, based on atmospheric interactions with large bodies of water. Meteorologists study meteorological phenomena driven by solar radiation, Earth's rotation, ocean currents and other factors. These include everyday ...

Catering
Catering is the business of providing food services at a remote site or a site such as a hotel, hospital, pub, aircraft, cruise ship, park, festival, filming location or film studio. History of catering The earliest account of major services being catered in the United States was an event for William Howe of Philadelphia in 1778. The event served local foods that were a hit with the attendees, who eventually popularized catering as a career. The official industry began to be recognized around the 1820s, with the caterers being disproportionately African-American. The catering business began to form around 1820, centered in Philadelphia. Robert Bogle The industry began to professionalize under Robert Bogle who is recognized as "the originator of catering." Catering was originally done by servants of wealthy elites. Butlers and house slaves, who were often black, were in a good position to become caterers. Essentially, caterers in the 1860s were "public butlers" as they orga ...

Barrage Balloon
A barrage balloon is a type of airborne barrage, a large uncrewed tethered balloon used to defend ground targets against aircraft attack, by raising aloft steel cables which pose a severe risk of collision with hostile aircraft, making the attacker's approach difficult and hazardous. Early barrage balloons were often spherical. The kite balloon, having a shape and cable bridling that stabilizes the balloon and reduces drag, could be operated at higher wind speeds than a spherical balloon. Some examples carried small explosive charges that would be pulled up against the aircraft to ensure its destruction. Barrage balloons are not practical at higher altitudes due in large part to the cable's weight. First World War France, Germany, Italy, and the United Kingdom used barrage balloons in the First World War. While the French and German forces developed kite balloons, early British barrage balloons were spherical. Sometimes, especially around London, several balloons were used t ...
