Traigh Mhòr
The Tràigh Mhòr, in English 'Big Beach', is a large expanse of sand forming a magnificent white beach at the northern end of the island of Barra in the Outer Hebrides of Scotland, in the village of Ardmhor extending to the village of Eoligarry. The beach is made up of hard compacted sand. The tidal islet of Orosay lies at the north end of the beach. Airport In 1933 when a site was sought for Barra Airport (Scotland), Barra Airport, John MacPherson, the local postmaster (otherwise known as 'The Coddy') suggested that the beach, with its hard compact sand, be used for the runways. It is still in use, and is the only runway in the world washed twice a day by the tide. There are three runways, to allow for different wind directions. Three large visible markers mark the runways. When the windsock flies to show that a plane arrival is imminent, the area is out of bounds to people on the beach. Cockling The Tràigh Mhòr is also popular with Cockle (bivalve), cockle pickers - the sou ...

Barra
Barra (; or ; ) is an island in the Outer Hebrides, Scotland, and the second southernmost inhabited island there, after the adjacent island of Vatersay to which it is connected by the Vatersay Causeway. In 2011, the population was 1,174. English and Gaelic are widely spoken, and at the 2011 Census, there were 761 Gaelic speakers (62% of the population, falling from 76% in the 1991 census). Geology In common with the rest of the Western Isles, Barra is formed from the oldest rocks in Britain, the Lewisian gneiss, which dates from the Archean, Archaean eon. Some of the gneiss in the east of the island is noted as being pyroxene-bearing. Layered textures or Foliation (geology), foliation in this metamorphic rock is typically around 30° to the east or northeast. Palaeoproterozoic age diorite, metadiorites and tonalite, metatonalites forming a part of the East Barra Meta-igneous Complex occur around Castlebay as they do on the neighbouring islands of Vatersay and Flodday, So ...

Outer Hebrides
The Outer Hebrides ( ) or Western Isles ( , or ), sometimes known as the Long Isle or Long Island (), is an Archipelago, island chain off the west coast of mainland Scotland. It is the longest archipelago in the British Isles. The islands form part of the archipelago of the Hebrides, separated from the Scottish mainland and from the Inner Hebrides by the waters of the Minch, the Little Minch, and the Sea of the Hebrides. The Outer Hebrides are considered to be the traditional heartland of the Gaelic language. The islands form one of the 32 council areas of Scotland, which since 1998 has used only the Gaelic form of its name, including in English language contexts. The council area is called Na h-Eileanan an Iar ('the Western Isles') and its council is ('Council of the Western Isles'). Most of the islands have a bedrock formed from ancient metamorphic rocks, and the climate is mild and oceanic. The 15 inhabited islands had a total population of in and there are more th ...

Twin Otter G-HIAL Leaving Barra For Glasgow
Twins are two offspring produced by the same pregnancy.MedicineNet > Definition of Twin Last Editorial Review: 19 June 2000 Twins can be either ''monozygotic'' ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or ''dizygotic'' ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell. Since identical twins develop from one zygote, they will share the same sex, while fraternal twins may or may not. In very rare cases, fraternal or (semi-) identical twins can have the same mother and different fathers (superfecundation, heteropaternal superfecundation). In contrast, a fetus that develops alone in the uterus, womb (the much more common case in humans) is called a ''singleton'', and the general term for one offspring of a multiple birth is a ''multiple''. Unrelated look-alikes whose resemblance parallels that of twins are referred to as doppelgänger. Statistics T ...

Barra Airport (Scotland)
Barra Airport () (also known as Barra Eoligarry Airport) is a short-runway airport (or STOLport) situated in the wide shallow bay of Traigh Mhòr at the northern tip of the island of Barra in the Outer Hebrides, Scotland. The airport is unique, believed to be the only one in the world where scheduled flights use a tide, tidal beach as the runway. The airport is operated by Highlands and Islands Airports Limited, which owns most of the regional airports in mainland Scotland and the outlying islands. Barra Airport opened in 1936. The airport's only destination is Glasgow. Infrastructure The beach is set out with three runways in a triangle, marked by permanent wooden poles at their ends, in Runway#Orientation and dimensions, directions 07/25, 11/29, 15/33. This means that almost always the de Havilland Canada DHC-6 Twin Otter, DHC-6 Twin Otter aircraft that serve the airport can land into the wind. At high tide, these runways are under the sea; flight times vary with the tide. E ...

Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ...

Windsock
A windsock (also known as wind cone or wind sleeve) is a conical textile tube that resembles a giant sock. It can be used as a basic indicator of wind speed and direction, or as decoration. Windsocks are typically used at airports to show the direction and strength of the wind to pilots, and at chemical plants where there is risk of gaseous leakage. They are also sometimes located alongside highways at windy locations. At many airports, windsocks are externally or internally lit at night. Wind direction is opposite the direction in which the windsock is pointing. Wind speed is indicated by the windsock's angle relative to the mounting polein low winds it droops; in high winds, it flies horizontally. Design Alternating stripes of high-visibility orange and white were initially used to help estimate wind speed, with each stripe extended adding 3 knots (5.6km/h; 3.5mph) to the estimated speed. Some circular frame mountings cause windsocks to be held open at one end and the firs ...

Cockle (bivalve)
A cockle is an edible marine bivalve mollusc. Although many small edible bivalves are loosely called cockles, true cockles are species in the family Cardiidae.>MolluscaBase eds. (2022). MolluscaBase. Cardiidae Lamarck, 1809. Accessed through: World Register of Marine Species on 2022-02-09/ref> True cockles live in sandy, sheltered beaches throughout the world. The distinctive rounded shells are bilaterally symmetrical, and are heart-shaped when viewed from the end. Numerous radial, evenly spaced ribs are a feature of the shell in most but not all genera (for an exception, see the genus '' Laevicardium'', the egg cockles, which have very smooth shells). The shell of a cockle is able to close completely (i.e., there is no "gap" at any point around the edge). Though the shell of a cockle may superficially resemble that of a scallop because of the ribs, cockles can be distinguished from scallops morphologically in that cockle shells lack "auricles" (triangular ear-shaped protrusi ...

Razor Shell
The razor shell, ''Ensis magnus'', also called razor clam, razor fish or spoot (colloquially), is a bivalve of the family Pharidae. It is found on sandy beaches in Canada and northern Europe (north of the Bay of Biscay). In some locations, the common name "razor shell" is also used to refer to members of the family Solenidae, including species of the genera ''Ensis'' and '' Solen'', by some taxonomic classifications which include the family Pharidae within the family Solenidae. It prefers coarser sand than its relatives '' E. ensis'' and '' E. siliqua''. Description It is known for its elongated, rectangular shape, which presents a similarity to the straight razor, hence its name. The razor shell has been known to reach in length. The dorsal margin is straight while the ventral margin is curved. It can easily be confused with the slightly shorter and more curved ''E. ensis'' (in which both front and back are curved in parallel). Razor shells have a fragile shell, with open en ...

Common Periwinkle
The common periwinkle or winkle (''Littorina littorea'') is a species of small edible whelk or sea snail, a marine gastropod mollusc that has gills and an operculum, and is classified within the family Littorinidae, the periwinkles. This is a robust intertidal species with a dark and sometimes banded shell. It is native to the rocky shores of the northeastern, and introduced to the northwestern, Atlantic Ocean. Description The shell is broadly ovate, thick, and sharply pointed except when eroded. The shell contains six to seven whorls with some fine threads and wrinkles. The color varies from grayish to gray-brown, often with dark spiral bands. The base of the columella is white. The shell lacks an umbilicus. The white outer lip is sometimes checkered with brown patches. The inside of the shell is chocolate brown. The width of the shell ranges from at maturity, with an average length of . Shell height can reach up to ,

Fish Factory
A fish factory, also known as a fish plant or fish processing facility, is a facility in which fish processing is performed. They are commonly located near bodies of water but can be located inland and on fishing vessels. The availability and variety of fish influences the scale of fish factories and the processing methods they utilize. The modernization of these facilities has promoted the use of machinery to increase production speed in order to meet the increasing global demand. Heightened demand has led to the increased production of fish and fish products which after processed result in large quantities of pollutants namely fish waste. Fish factories are held accountable for their product quality and are subject to a variety of health and safety regulations. Most regulations applicable to fish factories are limited, there are no universal regulations. Byproduct recovery is a method of waste mitigation that utilizes the waste produced by fish factories to produce other products ...
