C-21 Learjet
The Learjet Model 35 and Model 36 are a series of American multi-role business jets and military transport aircraft manufactured by Learjet. When used by the United States Air Force they carry the designation C-21A. The aircraft are powered by two Garrett TFE731-2 turbofan engines. Its cabin can be arranged for six to eight passengers. The longer-range Model 36 has a shortened passenger area to provide more space in the aft fuselage for fuel tanks. The engines are mounted in nacelles on the sides of the aft fuselage. The wings are equipped with single-slotted flaps. The wingtip fuel tanks distinguish the design from other aircraft having similar functions. Development The concept which became the LJ35 began as the Learjet 25BGF (with GF referring to "Garrett Fan"), a Learjet 25 with a then-new TFE731 turbofan engine mounted on the left side in place of the 25's General Electric CJ610 turbojet engine. This testbed aircraft first flew in May, 1971.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Falklands War
The Falklands War ( es, link=no, Guerra de las Malvinas) was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict was a major episode in the protracted dispute over the territories' sovereignt ...

375th Airlift Wing
The 375th Air Mobility Wing (375 AMW) is a unit of the United States Air Force stationed at Scott Air Force Base, Illinois and assigned to Eighteenth Air Force under Air Mobility Command (AMC). The wing has four primary missions. It supports aeromedical evacuation within the United States. It provides operational support airlift for government officials. It offers direct security for U.S. community and nation. And it provides support for U.S. host units—making possible the command and control of the United States' entire military transportation effort.

Air Mobility Command
Air Mobility Command (AMC) is a major command (MAJCOM) of the U.S. Air Force. It is headquartered at Scott Air Force Base, Illinois, east of St. Louis, Missouri. Air Mobility Command was established on 1 June 1992, and was formed from elements of the inactivated Military Airlift Command (MAC) and Strategic Air Command (SAC). AMC melded MAC's worldwide airlift system of primarily C-5 Galaxy, C-141 Starlifter (later replaced by C-17 Globemaster III beginning in 1995), and C-130 Hercules airlift aircraft with SAC's tanker force of KC-135 Stratotanker and KC-10 Extender aerial refueling aircraft, the latter air refueling aircraft having been freed from their strategic nuclear strike commitment to SAC's B-52 Stratofortress and B-1 Lancer bomber fleet by the end of the Cold War and the dissolution of the Soviet Union. Overview Air Mobility Command's mission is to provide global air mobility. The command also plays a crucial role in providing humanitarian support at home and arou ...

Air National Guard
The Air National Guard (ANG), also known as the Air Guard, is a federal military reserve force of the United States Air Force, as well as the air militia of each U.S. state, the District of Columbia, the Commonwealth of Puerto Rico, and the territories of Guam and the U.S. Virgin Islands. It, along with each state's, district's, commonwealth's or territory's Army National Guard component, makes up the National Guard of each state and the districts, commonwealths and territories as applicable. When Air National Guard units are used under the jurisdiction of the state governor they are fulfilling their militia role. However, if federalized by order of the President of the United States, Air National Guard units become an active part of the United States Air Force. They are jointly administered by the states and the National Guard Bureau, a joint bureau of the Army and Air Force that oversees the United States National Guard. Air National Guard operating forces are structured wh ...

Litter (rescue Basket)
A litter is a stretcher or basket designed to be used where there are obstacles to movement or other hazards: for example, in confined spaces, on slopes, in wooded terrain. Typically it is shaped to accommodate an adult in a face up position and it is used in search and rescue operations. The person is strapped into the basket, making safe evacuation possible. The person generally is further protected by a cervical collar and sometimes a long spine board, so as to immobilize the person and prevent further injury. A litter essentially is a stretcher with sides (or just a raised edge) and a removable head/torso cover. They are most notably remembered from Korea and Vietnam images of United States Air Force Pararescue airmen or more recent Coast Guard video clips of helicopters rescuing injured people from isolated areas. Some will also recall the images from the TV shows ''Emergency!'' and ''M*A*S*H'' of fixed stretchers on either side of medical evacuation helicopters. One widel ...

Type Certificate
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, primary category aircraft, certification costs around US$1m, US$25m for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes. The TC reflects a determination made by a regulatory authority that the type desig ...

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ...
