The University Of The South
The University of the South, familiarly known as Sewanee (), is a private Episcopal liberal arts college in Sewanee, Tennessee. It is owned by 28 southern dioceses of the Episcopal Church, and its School of Theology is an official seminary of the church.

History Beginning in the 1830s Bishop James Otey of Tennessee led an effort to found an Episcopal seminary in the Deep South. Following the Mexican War the Episcopal Church saw tremendous growth in the region, and a real need for an institution "to train natives, for natives" as Otey put it arose. Up to that point only the Virginia Theological Seminary in Alexandria, Virginia existed south of the Mason-Dixon Line and other den ...

Academic Tenure
Tenure is a category of academic appointment existing in some countries. A tenured post is an indefinite academic appointment that can be terminated only for cause or under extraordinary circumstances, such as financial exigency or program discontinuation. Tenure is a means of defending the principle of academic freedom, which holds that it is beneficial for society in the long run if scholars are free to hold and examine a variety of views. By country United States and Canada Under the tenure systems adopted by many universities and colleges in the United States and Canada, some faculty positions have tenure and some do not. Typical systems (such as the widely adopted "1940 Statement of Principles on Academic Freedom and Tenure" of the American Association of University Professors) allow only a limited period to establish a record of published research, ability to attract grant funding, academic visibility, teaching excellence, and administrative or community service.

Ninety-Nines
The Ninety-Nines: International Organization of Women Pilots, also known as The 99s, is an international organization that provides networking, mentoring, and flight scholarship opportunities to recreational and professional female pilots. Founded in 1929, the Ninety-Nines has 153 chapters and 27 regional 'sections' across the globe as of 2022, including a 'virtual' chapter, Ambassador 99s, which meets online for those who are too busy or mobile to be in one region for long. Amelia Earhart was elected as their first president in 1931, and the organization has continued to make a significant impact supporting the advancement of women in aviation since its inception. In 1982, the Ninety-Nines received the National Aviation Hall of Fame Spirit of Flight Award, and were inducted into the Oklahoma Air Space Museum Hall of Fame in 2001. In 2002, the organization was selected as the recipient of the Frank G. Brewer Trophy by the National Aeronautic Association, and in 2014 became induc ...

Federal Aviation Administration
The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrounding international waters. Its powers include air traffic management, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. Created in , the FAA replaced the former Civil Aeronautics Administration (CAA) and later became an agency within the U.S. Department of Transportation. Major functions The FAA's roles include: *Regulating U.S. commercial space transportation *Regulating air navigation facilities' geometric and flight inspection standards *Encouraging and developing civil aeronautics, including new aviation technology *Issuing, suspending, or revoking ...

Aircraft Owners And Pilots Association
The Aircraft Owners and Pilots Association (AOPA) is a Frederick, Maryland-based American non-profit political organization that advocates for general aviation. AOPA's membership consists mainly of general aviation pilots in the United States. AOPA exists to serve the interests of its members as aircraft owners and pilots and to promote the economy, safety, utility, and popularity of flight in general aviation aircraft. With 384,915 members in 2012, AOPA is the largest aviation association in the world, although it had decreased in membership from 414,224 in 2010, a loss of 7% in two years. AOPA is affiliated with other similar organizations in other countries through membership in the International Council of Aircraft Owner and Pilot Associations (IAOPA). In 2015, AOPA was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum. History The organization started at Wings Field in Blue Bell, Pennsylvania.

The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station.

University Of Tennessee Space Institute
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Spin (aerodynamics)
In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a crash may require a specific and counter-intuitive set of actions. A spin differs from a spiral dive, in which neither wing is stalled an ...
