John D. Craig
John D. Craig (1903–1997) was an American businessman, writer, soldier, diver, Hollywood stunt man, film producer, and television host. He worked in the commercial surface-supplied diving industry from the 1930s on, and filmed aerial combat over Europe during World War II. He is best known for using film and television to show the United States public the beauties and dangers of Earth's underwater worlds. Early life John D. Craig was born 28 April 1903 in Cincinnati, Ohio, one of five sons of a Scots immigrant John Craig. His father was born in Dalry, Scotland in 1868. Because the younger Craig was not given a middle name, he used "D." to create a stage name. He took the "D" from his youngest brother David, born in 1914. John Craig's older brother Tom was born in New York in 1901. The Craig family moved to Long Beach, California, where the boys spent formative years. In the early 1920s, the younger John Craig made his fortune investing in oil wells at Signal Hill, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bullion
Bullion is non-ferrous metal that has been refined to a high standard of elemental purity. The term is ordinarily applied to bulk metal used in the production of coins and especially to precious metals such as gold and silver. It comes from the Anglo-Norman term for a melting-house where metal was refined, and earlier from French , "boiling". Although precious metal bullion is no longer used to make coins for general circulation, it continues to be held as an investment with a reputation for stability in periods of economic uncertainty. To assess the purity of gold bullion, the centuries-old technique of fire assay is still employed, together with modern spectroscopic instrumentation, to accurately determine its quality. As investment The specifications of bullion are often regulated by market bodies or legislation. In the European Union, the minimum purity for gold to be referred to as "bullion", which is treated as investment gold with regard to taxation, is 99.5% for gol ...

Operation Tidal Wave
Operation Tidal Wave was an air attack by bombers of the United States Army Air Forces (USAAF) based in Libya on nine oil refineries around Ploiești, Romania on 1 August 1943, during World War II. It was a strategic bombing mission and part of the " oil campaign" to deny petroleum-based fuel to the Axis powers. The mission resulted in "no curtailment of overall product output". This operation was one of the costliest for the USAAF in the European Theater, with 53 aircraft and 660 air crewmen lost. It was proportionally the most costly major Allied air raid of the war, and its date was later referred to as "Black Sunday". Five Medals of Honor and 56 Distinguished Service Crosses along with numerous others awards went to Operation Tidal Wave crew members. A 1999 research report prepared for the Air War College at Maxwell Air Force Base in Alabama concluded that the bombing campaign in Ploiești was "one of the bloodiest and most heroic missions of all time". One of the downed A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-Day
The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France (and later western Europe) and laid the foundations of the Allied victory on the Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on D-Day was far from ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month were d ...

Cairo, Egypt
Cairo ( ; ar, القاهرة, al-Qāhirah, ) is the capital of Egypt and its largest city, home to 10 million people. It is also part of the largest urban agglomeration in Africa, the Arab world and the Middle East: The Greater Cairo metropolitan area, with a population of 21.9 million, is the 12th-largest in the world by population. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are located in its geographical area. Located near the Nile Delta, the city first developed as Fustat, a settlement founded after the Muslim conquest of Egypt in 640 next to an existing ancient Roman fortress, Babylon. Under the Fatimid dynasty a new city, ''al-Qāhirah'', was founded nearby in 969. It later superseded Fustat as the main urban centre during the Ayyubid and Mamluk periods (12th–16th centuries). Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mexican Crown Jewels
The Imperial Crown of Mexico was the crown created for the Sovereign of Mexico on two separate occasions in the 19th century. The first was created upon the Declaration of Independence of the Mexican Empire from the kingdom of Spain in 1821, for the First Mexican Empire. The second crown was created upon the decree of the Assembly of Notables in 1863 for the Second Mexican Empire. First Mexican Empire The crown of the First Mexican Empire was made for Emperor Agustín I in 1822, and it can be seen in many of his portraits. However, its history is not entirely known.

Nitrogen Narcosis
Narcosis while diving (also known as nitrogen narcosis, inert gas narcosis, raptures of the deep, Martini effect) is a reversible alteration in consciousness that occurs while diving at depth. It is caused by the anesthetic effect of certain gases at high pressure. The Greek word (narkōsis), "the act of making numb", is derived from (narkē), "numbness, torpor", a term used by Homer and Hippocrates. Narcosis produces a state similar to drunkenness (alcohol intoxication), or nitrous oxide inhalation. It can occur during shallow dives, but does not usually become noticeable at depths less than . Except for helium and probably neon, all gases that can be breathed have a narcotic effect, although widely varying in degree. The effect is consistently greater for gases with a higher lipid solubility, and although the mechanism of this phenomenon is still not fully clear, there is good evidence that the two properties are mechanistically related. As depth increases, the mental im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliox
Heliox is a breathing gas mixture of helium (He) and oxygen (O2). It is used as a medical treatment for patients with difficulty breathing because mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs. It is also used as a breathing gas diluent for deep ambient pressure diving as it is not narcotic at high pressure, and for its low work of breathing. Heliox has been used medically since the 1930s, and although the medical community adopted it initially to alleviate symptoms of upper airway obstruction, its range of medical uses has since expanded greatly, mostly because of the low density of the gas. Heliox is also used in saturation diving and sometimes during the deep phase of technical dives. Medical uses In medicine heliox may refer to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available (70/30 and 60/40). Hel ...

DESCO
DESCO is an underwater diving equipment maker which was first organized in 1937 in Milwaukee, Wisconsin as Diving Equipment and Salvage Co. It was founded by: * Max Eugene Nohl, a diver who lived in Milwaukee. In the early 1930s he had national publicity for his salvage operations on a sunken steamship, the '' John Dwight''. * John D. Craig, a Hollywood movie producer, a pioneer in underwater photography, who wanted to film the possible salvage of the . * Jack Browne, a diver. * Edgar End, a physician who worked in hyperbaric medicine. In 1935, Nohl, Craig and Browne designed a lightweight heliox diving suit to dive to the liner Lusitania, sunk in May 1915 by a German U-boat in 312 feet of water, 11 miles (18 km) off the southern coast of Ireland. On 1 December 1937 in Lake Michigan, Max Nohl dived to with DESCO equipment, breaking the previous record of set by British divers in 1930. In World War II DESCO made hardhat diving gear and oxygen rebreathers for the US Navy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
