Eldorado Radium Silver Express
The Eldorado Radium Silver Express (alternately Radium Express) was the name of a semi-regular air service between Edmonton, Alberta and Port Radium, Northwest Territories, or between Port Radium and a refinery at Port Hope, Ontario. ,mirror pages 28-30 A single airplane, a Bellanca Aircruiser, a small bush plane, provided this service, from 1935 to 1947. During the late 1930s Port Radium was one of the few sources of radium. During World War II, the mine was the main source for the uranium used by the atomic bomb program. Other than the air charter, goods and personnel could only be conveyed to and from the northernmost terminus of the North American railway grid, at Waterways, Alberta, was by water, a trip that took weeks. The rivers are frozen almost eight months of the year, closing down the initial leg of the trip. The plane crashed in northern Ontario in 1947. The Western Canada Aviation Museum is trying to restore the aircraft. Eldorado Aviation continued to ope ...

Eldorado Radium Silver Express -b
El Dorado (, ; Spanish language, Spanish for "the golden"), originally ''El Hombre Dorado'' ("The Golden Man") or ''El Rey Dorado'' ("The Golden King"), was the term used by the Spanish in the 16th century to describe a mythical tribal chief (''zipa'') or king of the Muisca people, an indigenous peoples of Colombia, indigenous people of the Altiplano Cundiboyacense of Colombia, who as an initiation rite, covered himself with gold dust and submerged in Lake Guatavita. The legends surrounding El Dorado changed over time, as it went from being a man, to a city, to a kingdom, and then finally to an empire. A second location for El Dorado was inferred from rumors, which inspired several unsuccessful expeditions in the late 1500s in search of a city called Manoa on the shores of Lake Parime or Parima. Two of the most famous of these expeditions were led by Sir Walter Raleigh. In pursuit of the legend, Spanish conquistadors and numerous others searched what is today Colombia, Venezuela ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ...

Regional Airlines Of The Northwest Territories
In geography, regions, otherwise referred to as zones, lands or territories, are areas that are broadly divided by physical characteristics (physical geography), human impact characteristics (human geography), and the interaction of humanity and the environment (environmental geography). Geographic regions and sub-regions are mostly described by their imprecisely defined, and sometimes transitory boundaries, except in human geography, where jurisdiction areas such as national borders are defined in law. Apart from the global continental regions, there are also hydrospheric and atmospheric regions that cover the oceans, and discrete climates above the land and water masses of the planet. The land and water global regions are divided into subregions geographically bounded by large geological features that influence large-scale ecologies, such as plains and features. As a way of describing spatial areas, the concept of regions is important and widely used among the many branches of ...

Waterways, Alberta
Waterways is a locality within the Regional Municipality of Wood Buffalo in northern Alberta, Canada. It is now a neighbourhood within the Fort McMurray urban service area along the west bank of the Clearwater River, south of the river's confluence with the Athabasca River. History In 1921, Waterways became a major shipping hub when the Alberta and Great Waterways Railway reached the town, making it the northernmost point on the North American railroad grid. Cargo for destinations farther north was shipped to Waterways and then transferred to barges, after which fleets of tugboats took them to destinations in the Mackenzie River watershed. In 1930, Dr. Karl A. Clark shipped a plant designed to separate bitumen from the Athabasca oil sands to Waterways and set it up nearby across the Clearwater River. Since that time, the rail line to Waterways has played an important role in transporting heavy equipment and supplies needed for the development of the oil sands and the ...

Transportation In North America
Transportation in North America is performed through a varied transportation system, whose quality ranges from being on par with a high-quality European motorway to an unpaved gravelled back road that can extend hundreds of miles. There is also an extensive transcontinental freight rail network, but passenger railway ridership is lower than in Europe and Asia. Railways Canada, the United States and Mexico The railroad network of North America (using standard gauge) is extremely extensive, connecting nearly every major and most minor cities. The United States, Canada, and Mexico have an interconnected system with railheads stretching from Hay River, Northwest Territories, Canada, to Tapachula, Mexico, and on Vancouver Island. The state government of Alaska also operates the Alaska Railroad, which does not connect to the North American network. In Canada, rail lines from Labrador City, Newfoundland and Labrador, to Sept-Îles, Quebec, also are not linked to the North America ...

Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ...
