It flows north - westwards from its source and joins the Afon Artro at Pentre Gwynfryn ., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., Wrexham (; ) is a large town in north Wales, between the Welsh mountains and the lower Dee Valley alongside the border with England.

(Including Old Colwyn, Rhos-on-Sea, Mochdre and Llysfaen communities]. Locally nicknamed "The Bay"., Shropshire (or ; alternatively Salop; abbreviated, in print only, Shrops; demonym Salopian ) is a county located between West Midlands in England and Wales. It borders Powys and Wrexham in Wales to the west and north-west, Cheshire to the north, Staffordshire to the east, Worcestershire to the south-east and Herefordshire to the south. Shropshire Council was created in 2009, a unitary authority taking over from the previous county council and five district councils. The borough of Telford and Wrekin has been a separate unitary authority since 1998 but continues to be included in the ceremonial county., A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams., Powys (or ; Welsh: ) is a principal area, local-government county and preserved county in Mid Wales. It is named after the successor Kingdom of Powys, which formed after the Romans withdrew from Britain., Llandudno is a seaside resort, town and community in Conwy County Borough, Wales, located on the Creuddyn peninsula, which protrudes into the Irish Sea. In the 2011 UK census, the community, which includes Penrhyn Bay and Penrhynside, had a population of 20,701. The town's name is derived from its patron saint, Saint Tudno., A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas"., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south.

Retail, transport and educational infrastructure are centred on Wrexham, Rhyl, Colwyn Bay, Llandudno and Bangor. It is bordered to the south by the counties of Ceredigion and Powys in Mid Wales, and to the east by the counties of Shropshire in the West Midlands and Cheshire in North West England., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., Mid Wales (or simply "Y Canolbarth" "The Midlands") is the name given to the central region of Wales. The Mid Wales Regional Committee of the National Assembly for Wales covered the counties of Ceredigion and Powys and the area of Gwynedd that had previously been the district of Meirionydd. A similar definition is used by the BBC. The Wales Spatial Plan defines a region known as "Central Wales" which covers Ceredigion and Powys. If Mid Wales is classed as Ceredigion and Powys, the area would be 6,962 square kilometres (about the size of Cumbria)., A stream is a body of water with a current, confined within a bed and banks. Depending on its location or certain characteristics, a stream may be referred to as a "bayou", "beck", "branch", "brook", "burn", "creek", "crick", "ghyll", "gill", "kill", "lick", "mill race", "race", "rill", "river", "rivulet", "run", "runnel", "streamage", "syke", or "wash"., In hillslope geomorphology, a rill is a shallow channel (no more than a few tens of centimetres deep) cut into soil by the erosive action of flowing water. Similar but smaller incised channels are known as microrills; larger incised channels are known as gullies., Rhyl is a seaside resort town and community in the historic county of Denbighshire, situated on the north east coast of Wales, at the mouth of the River Clwyd (Welsh: "Afon Clwyd").

The conurbation of Abergele-Rhyl-Prestatyn has a population of over 60,000, with Rhyl-Kinmel Bay having 31,229 people., A watercourse is the channel that a flowing body of water follows. In the UK, some aspects of criminal law such as The Rivers (Prevention of Pollution) Act 1951 specify that a watercourse includes those rivers which are dry for part of the year., Cheshire (or ; archaically the County Palatine of Chester; abbreviated Ches.) is a county in North West England, bordering Merseyside and Greater Manchester to the north, Derbyshire to the east, Staffordshire and Shropshire to the south and Wales to the west (bordering Wrexham and Flintshire). Cheshire's county town is Chester; the largest town is Warrington., Ceredigion is a county in Mid Wales. In the Middle Ages, it was a minor kingdom also known for a time as Seisyllwg.

The company was founded on July 6, 1939 by James Smith McDonnell, and was best known for its military fighters, including the F-4 Phantom II, and manned spacecraft including the Mercury capsule and Gemini capsule. McDonnell Aircraft later merged with the Douglas Aircraft Company to form McDonnell Douglas in 1967., Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications., A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include those aircraft where one or more rotors are required to provide lift throughout the entire flight, such as helicopters, cyclocopters, autogyros, and gyrodynes. Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces., A rocket (from Italian "rocchetto" "bobbin") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space., The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas, Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas. Douglas Aircraft Company largely operated as a division of McDonnell Douglas (MD) after the merger. MD later merged with Boeing in 1997., The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, and satellites worldwide. The company also provides leasing and product support services.

Boeing stock is a component of the Dow Jones Industrial Average., Embraer S.A. is a Brazilian aerospace conglomerate that produces commercial, military, executive and agricultural aircraft and provides aeronautical services. It is headquartered in São José dos Campos, São Paulo State., McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced a number of well-known commercial and military aircraft such as the DC-10 airliner and F-15 Eagle air-superiority fighter., As of September 2015 , American Airlines operates a mainline fleet of 939 aircraft , making it the largest commercial fleet in the world . It primarily operates a mix of Airbus and Boeing ( including McDonnell Douglas ) narrow - body and wide - body aircraft , as well as one narrow - body variant from Embraer . American is currently in the process of the largest fleet renewal in its history , with over 300 aircraft on order from Airbus and Boeing . American Airlines also announced a new livery to be painted on all aircraft . American Airlines expects to be done repainting all aircraft by the end of 2017 ., 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., Subject: american airlines fleet, Relation: item_operated, Options: (A) 4 (B) aircraft (C) airliner (D) spacecraft

Context: Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards., Nuclear Blast is an independent record label and mail order record distributor with subsidiaries in Germany, the United States and Brazil. The record label was founded in 1987 by Markus Staiger in Germany. Originally releasing hardcore punk records, the label moved on to releasing albums by melodic death metal, grindcore, industrial metal, power metal and black metal bands, as well as tribute albums., Hard rock is a loosely defined subgenre of rock music that began in the mid-1960s, with the garage, psychedelic and blues rock movements. It is typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, drums, and often accompanied with pianos and keyboards., Speed metal is an extreme subgenre of heavy metal music that originated in the late 1970s from new wave of British heavy metal (NWOBHM) roots. It is described by AllMusic as "extremely fast, abrasive, and technically demanding" music., Iron Butterfly is an American rock band best known for the 1968 hit "In-A-Gadda-Da-Vida", providing a dramatic sound that led the way towards the development of hard rock and heavy metal music. Formed in San Diego, California, among band members who used to be "arch enemies", their heyday was the late 1960s, but the band has been reincarnated with various members with varying levels of success, with no new recordings since 1975. The band's seminal 1968 album "In-A-Gadda-Da-Vida" is among the world's 40 best-selling albums, selling more than 30 million copies. Iron Butterfly is also notable for being the first group to receive an RIAA platinum award., A Twist in the Myth is the eighth studio album by the German heavy metal band Blind Guardian. It was originally set to be released on September 5, 2006 in Europe (which became the North American release date), but Nuclear Blast changed the release date to September 1, 2006., Hans Jürgen Kürsch, better known as Hansi Kürsch (born 10 August 1966 in Lank-Latum/Meerbusch, Germany) is a German singer, bass guitarist, and songwriter, best known for being the co-founder, lead vocalist, co-composer, and lyricist of power metal band Blind Guardian. He was also the bassist in Blind Guardian until the 1998 album "Nightfall in Middle-Earth". He also provides lead vocals for the band Demons and Wizards., Blind Guardian is a German power metal band formed in the mid-1980s in Krefeld, West Germany. They are often credited as one of the seminal and most influential bands in the power metal and speed metal subgenres.

The single also includes a cover of Iron Butterfly 's `` In - A - Gadda - Da - Vida '' , also available only on the single . Vocalist Hansi Kürsch has said that while `` Fly '' is a surprising title for a Blind Guardian song , it fits very well with the lyrics . He added , `` This song is about inspirations and how they can influence your art , your life and other people 's lives . I , myself , was inspired by the movie Finding Neverland when doing the lyrics .
