Question: Is Air Traffic or Halestorm an American band?
Context: Halestorm is an American hard rock band from Red Lion, Pennsylvania, consisting of lead vocalist and guitarist Lzzy Hale, her brother drummer and percussionist Arejay Hale, guitarist Joe Hottinger, and bassist Josh Smith.  The group's self-titled debut album was released on April 28, 2009, through Atlantic Records.  Their second album "The Strange Case Of..." was released on April 10, 2012.  Its lead single "Love Bites (So Do I)" from that album won their first Grammy Award for Best Hard Rock/Metal Performance on February 10, 2013. Deutsche Flugsicherung (DFS) is the company in charge of air traffic control for Germany.  It is a company organized under private law and 100% owned by the Federal Republic of Germany.  Since January 1993, DFS has been controlling air traffic in Germany.  In Germany, military and civil air traffic controllers work side by side.  Since 1994, DFS has been responsible for the handling of both civil and military air traffic in peacetime.  Only military aerodromes are exempted from this integration. An Air traffic obstacle is a tall structure which can endanger air traffic.  Air traffic obstacles have to be marked in most cases with red and white colored markings and with aircraft warning lights at night.  On larger structures blinking lights are required.  An example of an air traffic obstacle is the air traffic control tower. NATS Holdings, formerly National Air Traffic Services and commonly referred to as NATS, is the main Air Navigation Service Provider in the United Kingdom.  It inherited the traditions of UK air traffic control, which (founded over Croydon Airport) was the world's first air traffic control regime.  It provides en-route air traffic control services to flights within the UK Flight Information Regions and the Shanwick Oceanic Control Area, and provides air traffic control services to fourteen UK airports. Air Traffic Chaos is an air traffic controller simulation video game developed and published by Majesco Entertainment for the Nintendo DS handheld video game console.  It has previously been released in Japan under the name ぼくは航空管制官 ("I Am An Air Traffic Controller"), and later in Europe under the title "Air Traffic Controller by DS".  A video game demo was made available before its release for the Wii's Nintendo Channel. Air traffic management is an aviation term encompassing all systems that assist aircraft to depart from an aerodrome, transit airspace, and land at a destination aerodrome, including air traffic control (ATC), air traffic safety electronics personnel (ATSEP), aeronautical meteorology, air navigation systems (aids to navigation), Air Space Management (ASM), Air Traffic Services (ATS), and Air Traffic Flow Management (ATFM), or Air Traffic Flow and Capacity Management (ATFCM). Air traffic controllers are personnel responsible for the safe, orderly, and expeditious flow of air traffic in the global air traffic control system.  Usually stationed in air traffic control centers and control towers on the ground, they monitor the position, speed, and altitude of aircraft in their assigned airspace visually and by radar, and give directions to the pilots by radio.  The position of air traffic controller is one that requires highly specialized knowledge, skills, and abilities.  Controllers apply separation rules to keep aircraft at a safe distance from each other in their area of responsibility and move all aircraft safely and efficiently through their assigned sector of airspace, as well as on the ground.  Because controllers have an incredibly large responsibility while on duty (often in aviation, "on position") and make countless real-time decisions on a daily basis, the ATC profession is consistently regarded around the world as one of the most mentally challenging careers, and can be notoriously stressful depending on many variables (equipment, configurations, weather, traffic volume, human factors, etc.).  Many controllers, however, would cite high salaries, and a very large, unique, and privileged degree of autonomy as major advantages of their jobs. NATCON (Norwegian Air Traffic Control System) is a nationwide Air Traffic Management system which is used by air traffic controllers in control towers (TWR), approach centres (APP) and area control centres (ACC) in Norway.  The system is based on Auto Trac Air Traffic Management System from Raytheon (US) which also includes a flight data processing system originally developed by Indra (Spain). ATC Zero (Air Traffic Control Zero) is an official term used by the U.S. Federal Aviation Administration (FAA) that means the FAA is unable to safely provide the published ATC (air traffic control) services within the airspace managed by a specific facility.  The term is always used in conjunction with a facility reference.  FAA ATC facilities include Air Route Traffic Control Centers (ARTCC); Terminal Radar Control facility (TRACON), Air Traffic Control Tower (ATCT), Flight Service Stations (FSS), or the Air Traffic Control System Command Center(ATCSCC).  The term is defined in FAA Order JO 1900.47, Air Traffic Control Operational Contingency Plans.  It is one of three designations used by the FAA (ATC Alert, ATC Limited, and ATC Zero) to describe degraded operations and invoke operational contingency plans. Air Traffic are an English alternative rock band from Bournemouth.  Formed in 2003, the band consists of Chris Wall (piano, lead vocals), David Ryan Jordan (Drums), Tom Pritchard (guitar) and Jim Maddock (bass guitar).
