United States Air Force

The United States Air Force (USAF) is the aerial warfare service branch of the United States Armed Forces and one of the seven American uniformed services. Initially part of the United States Army, the USAF was formed as a separate branch of the military on 18 September 1947 under the National Security Act of 1947. It is the most recent branch of the U.S. military to be formed, and is the largest and one of the world's most technologically advanced air forces. The USAF articulates its core functions as Nuclear Deterrence Operations, Special Operations, Air Superiority, Global Integrated ISR, Space Superiority, Command and Control, Cyberspace Superiority, Personnel Recovery, Global Precision Attack, Building Partnerships, Rapid Global Mobility and Agile Combat Support.

The U.S. Air Force is a military service organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force is headed by the civilian Secretary of the Air Force, who reports to the Secretary of Defense, and is appointed by the President with Senate confirmation. The highest-ranking military officer in the Department of the Air Force is the Chief of Staff of the Air Force, who exercises supervision over Air Force units, and serves as a member of the Joint Chiefs of Staff. Air Force combat and mobility forces are assigned, as directed by the Secretary of Defense, to the Combatant Commanders, and neither the Secretary of the Air Force nor the Chief of Staff have operational command authority over them.

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.

Fourth Air Force

The Fourth Air Force (4 AF) is a numbered air force of the United States Air Force Reserve (AFRC). It is headquartered at March Air Reserve Base, California.

4 AF directs the activities and supervises the training of more than 30,000 Air Force Reservists. If called to active duty, 4 AF's ready reserve units would be assigned to Air Mobility Command.

One of the four original pre–World War II numbered air forces, 4 AF was activated on 18 December 1940, at March Field, California with a mission of air defense of the Southwestern United States and Lower Midwest regions. During the war, its primary mission became the organization and training of combat units prior to their deployment to the overseas combat air forces.

4 AF is commanded by Maj Gen Mark A. Kyle.

Overview

Fourth Air Force is dedicated to ensuring its units and personnel are fully prepared to accomplish all assigned missions in support of national objectives. The sixty person staff consists of Traditional Reservists, Air Reserve Technicians and civilian employees. They direct the activities and supervise the equipping and training of more than 30,000 Air Force reservists in unit programs located across the continental United States, Alaska, Hawaii and Guam. Reservists from 4 AF units are routinely deployed to Air Expeditionary units in combat areas of Central and Southwest Asia as part of the Global War on Terrorism.

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.

USAir Flight 427

USAir Flight 427 was a scheduled flight from Chicago's O'Hare International Airport to Pittsburgh International Airport, with a final destination of West Palm Beach, Florida. The flight crashed on Thursday, September 8, 1994, killing all 132 people on board. The Boeing 737-3B7 flying the route, registered N513AU, and previously registered as N382AU, was approaching runway 28R of Pittsburgh International Airport, located in Findlay Township, Allegheny County, Pennsylvania, which was at the time the largest hub for the airline.

Flight crew

The crew of Flight 427 were Captain Peter Germano, 45, hired by USAir in February 1981, and First Officer Charles B. "Chuck" Emmett III, 38, hired in February 1987 by Piedmont Airlines (which merged into USAir in 1989). Both the captain and first officer were regarded as excellent pilots. They were both very experienced, with approximately 12,000 flight hours and 9,119 flight hours respectively. Flight attendants Stanley Canty and April Slater were hired in 1989 by Piedmont Airlines. Flight attendant Sarah Slocum-Hamley was hired in October 1988 by USAir.

US Airways Flight 1549

On January 15, 2009, US Airways Flight 1549 (AWE1549), an Airbus A320 piloted by Captain Chesley B. "Sully" Sullenberger and First Officer Jeffrey Skiles, made an unpowered emergency water landing in the Hudson River after multiple bird strikes caused both jet engines to fail. All 155 occupants, the passengers and crew, successfully evacuated from the partially submerged airframe as it sank into the river; they were rescued by nearby watercraft. Several occupants suffered injuries, a few of them serious, but only one required hospitalization overnight. The incident came to be known as the "Miracle on the Hudson", and Captain Sullenberger and the crew were hailed as heroes.

The aircraft was an Airbus A320-200, registered N106US, operating as a US Airways scheduled domestic commercial passenger flight from LaGuardia Airport in New York City to Charlotte Douglas International Airport in Charlotte, North Carolina. About three minutes into the flight, at 3:27 p.m. EST, the plane struck a flock of Canada geese during its initial climb out from LaGuardia, just northeast of the George Washington Bridge. The bird strike caused both jet engines to quickly lose power.
