Corkscrew Landing
A corkscrew landing (also spiral landing) is a method of landing an aircraft that is intended to minimize the risk of the aircraft being hit by anti-aircraft fire from the ground as it approaches to land at a destination airport. Instead of slow descent towards the airport, in a corkscrew landing the aircraft is positioned at high altitude above the airport, then descends rapidly in a spiral. The maneuver is typically performed by pilots of military aircraft to avoid surface-to-air missiles. Technique A corkscrew landing involves positioning the aircraft over the landing site at altitude, then descending in a steeply banked spiral path. To do this the pilot of the aircraft banks the aircraft from the horizontal and begins a fast descent. Once closer to the airfield, the pilot will slowly level off and begin descent into the runway. History The corkscrew landing maneuver has been reported as being performed in the Vietnam War. It also became the standard method of landing by airli ...

Landing
Landing is the last part of a flight, where a flying animal, aircraft, or spacecraft returns to the ground. When the flying object returns to water, the process is called alighting, although it is commonly called "landing", "touchdown" or " splashdown" as well. A normal aircraft flight would include several parts of flight including taxi, takeoff, climb, cruise, descent and landing. Aircraft Aircraft usually land at an airport on a firm runway or helicopter landing pad, generally constructed of asphalt concrete, concrete, gravel or grass. Aircraft equipped with pontoons ( floatplane) or with a boat hull-shaped fuselage (a flying boat) are able to land on water. Aircraft also sometimes use skis to land on snow or ice. To land, the airspeed and the rate of descent are reduced such that the object descends at a low enough rate to allow for a gentle touch down. Landing is accomplished by slowing down and descending to the runway. This speed reduction is accomplished by r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. T ...

Bank Angle
A banked turn (or banking turn) is a turn or change of direction in which the vehicle banks or inclines, usually towards the inside of the turn. For a road or railroad this is usually due to the roadbed having a transverse down-slope towards the inside of the curve. The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal. Turn on flat surfaces If the bank angle is zero, the surface is flat and the normal force is vertically upward. The only force keeping the vehicle turning on its path is friction, or traction. This must be large enough to provide the centripetal force, a relationship that can be expressed as an inequality, assuming the car is driving in a circle of radius r: :\mu mg > . The expression on the right hand side is the centripetal acceleration multiplied by mass, the force required to turn the vehicle. The left hand side is the maximum frictional force, which equals the coefficient of friction \mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset.

Baghdad International Airport
Baghdad International Airport , previously Saddam International Airport from 1982 to 2003, () is Iraq's largest international airport, located in a suburb about west of downtown Baghdad in the Baghdad Governorate. It is the home base for Iraq's national airline, Iraqi Airways. History Interwar The Baghdad West Aerodrome was made available for civilian flights of Imperial Airways on April 1, 1929. It is unclear when the airport actually became the main airport of Baghdad, as it existed long before 1982, with what is now runway 15R/33L as the only runway. Until 1970, Al Muthanna Airport or Muthenna Air Base was the main airport of Baghdad. Construction and operation The airport was developed under a consortium led by French company Spie Batignolles under an agreement made in 1979. The Iran–Iraq War delayed full opening of the airport until 1982. It opened as Saddam International Airport, bearing the name of then- Iraqi President Saddam Hussein. Most of Baghdad's civ ...

2003 Baghdad DHL Attempted Shootdown Incident
On 22 November 2003, shortly after takeoff from Baghdad, Iraq, an Airbus A300B2-200F cargo plane, registered OO-DLL and owned by the Belgian division of European Air Transport (doing business as DHL Aviation), was struck on the left wing by a surface-to-air missile while on a scheduled flight to Muharraq, Bahrain. Severe wing damage resulted in a fire and List of airliner crashes involving loss of control, complete loss of hydraulic flight control systems. Because outboard left wing Fuel tank#Aircraft, fuel tank 1A was full at takeoff, no fuel-air vapour explosion occurred. Liquid jet fuel dropped away as 1A disintegrated. Inboard fuel tank 1 was pierced and leaking. Returning to Baghdad, the three-man crew made an injury-free landing of the seriously damaged A300, using differential engine thrust as the only pilot input. This was despite major damage to a wing, total loss of hydraulic control, a faster-than-safe landing speed, and a ground path that veered off the runway surface ...
