Q:Information: - Ciaran Eugene Gultnieks ( born 1970 ) is a British computer game programmer , whose projects include Star Wars ( 1988 , for home computers ) , Dogfight ( 1993 ) , Slipstream 5000 ( 1995 ) and Hardwar ( 1998 ) for the PC . He is the founder of F - Droid and contributes to the microblogging platform StatusNet . - A fighter aircraft is a military aircraft designed primarily for air-to-air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets. The hallmarks of a fighter are its speed, maneuverability, and small size relative to other combat aircraft. - A weapon, arm, or armament is any device used with intent to inflict damage or harm to living beings, structures, or systems. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, and warfare. In a broader context, weapons may be construed to include anything used to gain a strategic, material or mental advantage over an adversary. - The racing video game genre is the genre of video games, either in the first-person or third-person perspective, in which the player partakes in a racing competition with any type of land, air, or sea vehicles. They may be based on anything from real-world racing leagues to entirely fantastical settings. In general, they can be distributed along a spectrum anywhere between hardcore simulations, and simpler arcade racing games. Racing games may also fall under the category of sports games. - Basic fighter maneuvers (BFM) are tactical movements performed by fighter aircraft during air combat maneuvering (also called ACM, or dogfighting), in order to gain a positional advantage over the opponent. BFM combines the fundamentals of aerodynamic flight and the geometry of pursuit with the physics of managing the aircraft's energy-to-weight ratio, called its specific energy. Maneuvers are used to gain a better angular position in relation to the opponent. They can be offensive, to help an attacker get behind an enemy, or defensive, to help the defender evade an attacker's air-to-air weapons. They can also be neutral, where both opponents strive for an offensive position, or disengagement maneuvers, to help facilitate an escape. Awareness is often taught as the best tactical defense, removing the possibility of an attacker getting or remaining behind the pilot; even with speed a fighter is open to attack from the rear. Introduction. Basic fighter maneuvers are actions that a fighter aircraft makes during air combat maneuvering, historically known as dogfighting. The development of BFM began with the first fighter aircraft, during World War I, then continued with each following war, adapting to the changing weapons and technologies. - A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers. - Slipstream 5000 is a 3D racing video game developed by The Software Refinery and published by Gremlin Interactive for IBM PC compatible computers in July 1995. - IBM PC compatible computers are those similar to the original IBM PC, XT, and AT, able to run the same software and support the same expansion cards as those. Such computers used to be referred to as PC clones, or IBM clones. They duplicate almost exactly all the significant features of the PC architecture, facilitated by IBM's choice of commodity hardware components and various manufacturers' ability to reverse engineer the BIOS firmware using a "clean room design" technique. Columbia Data Products built the first clone of the IBM personal computer by a clean room implementation of its BIOS. - Gremlin Interactive (originally Gremlin Graphics) was a British software house based in Sheffield and working mostly in the home computer market. Like many software houses established in the 1980s, their primary market was the 8-bit range of computers such as the ZX Spectrum, Amstrad CPC, MSX, Commodore 16 and Commodore 64. - Aerial warfare is the use of military aircraft and other flying machines in warfare. Aerial warfare includes bombers attacking enemy concentrations or strategic targets; fighter aircraft battling for control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; gliders, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel. Historically, military aircraft have included lighter-than-air balloons carrying artillery observers; lighter-than-air airships for bombing cities; various sorts of reconnaissance, surveillance and early warning aircraft carrying observers, cameras and radar equipment; torpedo bombers to attack enemy shipping; and military air-sea rescue aircraft for saving downed airmen. Modern aerial warfare includes missiles and unmanned aerial vehicles. Surface forces are likely to respond to enemy air activity with anti-aircraft warfare. - The Software Refinery was a United Kingdom-based computer game development company formed by Ciaran Gultnieks, Ian Martin and Mark Griffiths. The company was based in the city of Leeds, West Yorkshire. - A dogfight, or dog fight, is an aerial battle between fighter aircraft, conducted at close range. Dogfighting first appeared during World WarI, shortly after the invention of the airplane. Until at least 1992, it was a component in every major war, despite beliefs after World WarII that increasingly greater speeds and longer range weapons would make dogfighting obsolete. Modern terminology for air-to-air combat is air combat maneuvering (ACM), which refers to tactical situations requiring the use of individual basic fighter maneuvers (BFM) to attack or evade one or more opponents. This differs from aerial warfare, which deals with the strategy involved in planning and executing various missions. - An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled.
