Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

Coast guard

A coast guard or coastguard is a maritime security organization of a particular country. The term implies widely different responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue functions and lacking any law enforcement powers. However, a typical coast guard's functions are distinct from typical functions of both the navy (a pure military force) and a transportation police (a civilian law enforcement agency).

History

The modern Her Majesty's Coastguard of the United Kingdom was established in 1809 as the Waterguard, and was originally devoted to the prevention of smuggling as a department of the HM Customs and Excise authority. It was, however, also responsible for giving assistance to shipwrecks.

Each Water Guard station was issued with Manby's Mortar which was invented by Captain George William Manby in 1808. The mortar fired a shot with a line attached from the shore to the wrecked ship and was used for many years up and down the coastline. This began the process in which the Coastguard assumed a life saving role. In 1821 a committee of inquiry recommended that responsibility for the Preventative Water Guard be transferred to the Board of Customs. The Treasury agreed and in a Minute dated 15 January 1822, directed that the preventative services, which consisted of the Preventative Water Guard, cruisers, and Riding Officers should be placed under the authority of the Board of Customs and in future should be named the Coast Guard. In 1845 the Coastguard was subordinated to the Admiralty.

US Airways

US Airways was a major American airline that ceased operations on October 17, 2015 after merging with American Airlines. It operated an extensive international and domestic network, with 193 destinations in 24 countries in North America, South America, Europe and the Middle East. The airline was an affiliate member of Oneworld and utilized a fleet of 343 mainline jet aircraft, as well as 278 regional jet and turbo-prop aircraft operated by contract and subsidiary airlines under the name US Airways Express.

The carrier operated the US Airways Shuttle, a US Airways brand which provided hourly service between Boston, New York City and Washington, D.C. As of October 2013, US Airways employed 32,312 people worldwide and operated 3,028 daily flights (1,241 US Airways Mainline, 1,790 US Airways Express) Roughly 60% of US Airways flights were operated by US Airways Express.

In 1979, after passage of the Airline Deregulation Act, Allegheny Airlines changed its name to USAir and began seeking to expand its operations. A decade later, it had acquired Piedmont Airlines and Pacific Southwest Airlines, and was one of the U.S.'s seven remaining transcontinental legacy carriers. In 2005, America West Airlines carried out a reverse merger, acquiring the assets and branding of the larger US Airways while putting the America West leadership team largely in charge of the merged airline.

Air Crew

Air Crew (Russian: Экипаж, translit. Ekipazh) is a movie produced by Mosfilm in 1979. Inspired by Airport movies series, it was the first catastrophe movie shot in the Soviet Union.

Plot

The first part of the film concentrates on the personal lives of the air crew, including their problems and relationships. For family reasons, one of the pilots has had to give up a promising career for a much less ambitious one. Despite this, his wife senses that he is not happy, which makes her a conflicted and angry spouse. Though both the parents love their son, it is not enough to prevent them from divorcing. Subsequently, the pilot resumes his career piloting the large passenger planes he had been hankering after. One of his pilot colleagues does not believe in family at all — his flat is full of impressive self-constructed light effects and son et lumière equipment that he uses to impress the parade of women he has one-night stands with.

Special operations

Special operations (S.O.) are military operations that are "special" or unconventional and carried out by dedicated special forces units using unconventional methods and resources. Special operations may be performed independently of or in conjunction with conventional military operations. The primary goal is to achieve a political or military objective where a conventional force requirement does not exist or might adversely affect the overall strategic outcome. Special operations are usually conducted in a low-profile manner that aims to achieve the advantages of speed, surprise, and violence of action against an unsuspecting target. Special ops are typically carried out with limited numbers of highly trained personnel that are adaptable, self-reliant and able to operate in all environments, and able to use unconventional combat skills and equipment. Special operations are usually implemented through specific, tailored intelligence.
