Suicide
Suicide is the act of intentionally causing one's own death. Mental disorders (including depression, bipolar disorder, schizophrenia, personality disorders, anxiety disorders), physical disorders (such as chronic fatigue syndrome), and substance abuse (including alcoholism and the use of and withdrawal from benzodiazepines) are risk factors. Some suicides are impulsive acts due to stress (such as from financial or academic difficulties), relationship problems (such as breakups or divorces), or harassment and bullying. Those who have previously attempted suicide are at a higher risk for future attempts. Effective suicide prevention efforts include limiting access to methods of suicide such as firearms, drugs, and poisons; treating mental disorders and substance abuse; careful media reporting about suicide; and improving economic conditions. Although crisis hotlines are common resources, their effectiveness has not been well studied. The most commonly adopted metho ...

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 to destroy aircraft or other missiles. It is one type of 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. This evolution of design increasin ...

Restricted Airspace
Restricted airspace is an area of airspace typically used by the military in which the local controlling authorities have determined that air traffic must be restricted or prohibited for safety or security concerns. It is one of many types of special use airspace designations and is depicted on aeronautical charts with the letter "R" followed by a serial number. According to the United States Federal Aviation Administration (FAA): "Restricted areas denote the existence of unusual, often invisible, hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles. Penetration of restricted areas without authorization from the using or controlling agency may be extremely hazardous to the aircraft and its occupants." Restricted airspace zones may not be active ("hot") at all times; in such cases there are typically schedules of local dates and times available to aviators specifying when the zone is active, and at other times, the airspace is subject to normal VFR/IF ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Blair House
Blair House, also known as The President's Guest House, is an official residence in Washington, D.C., the capital of the United States. The President's Guest House has been called "the world's most exclusive hotel" because it is primarily used as a state guest house to host visiting dignitaries and other guests of the president. Parts of the historic complex have been used for an official residence since the 1940s. Located just across Pennsylvania Avenue from the White House, it is a complex of four formerly separate homes—Blair House, Lee House, Peter Parker House, and 704 Jackson Place. Major interior renovation of these 19th century residences between the 1950s and 1980s resulted in them being joined together. Blair House is one of several residences owned by the United States government for use by the president and vice president of the United States; other such residences include the White House, Camp David, One Observatory Circle, the Presidential Townhouse, and Trowbr ...
