Escape And Evasion Map
Evasion charts or escape maps are maps made for servicemembers, and intended to be used when caught behind enemy lines to assist in performing escape and evasion. Such documents were secreted to prisoners of war by various means to aid in escape attempts. During World War II, these clandestine maps were used by many American, British, and allied servicemen to escape from behind enemy lines. Special material was used for this purpose, due to the need for a material that would be hardier than paper, and would not tear or dissolve in water.Garber, Megan. 2013"How Monopoly Games Helped Allied POWs Escape During World War II."The Atlantic. January 2013. Evasion charts produced for the US, UK, and NATO were printed on vinyl sheet in the 1960s. Modern evasion charts are made of Tyvek 'paper', which permit printing of minute detail while remaining waterproof and tear-resistant.

Roger Locher
Roger Clinton Locher (born September 13, 1946) is a retired Colonel in the U.S. Air Force and a former McDonnell Douglas F-4D Phantom II Navigator/Weapon Systems Officer (WSO) and subsequent Pilot who, during Operation Linebacker in the Vietnam War, was shot down only from Hanoi, North Vietnam. The 23 days Locher spent behind enemy lines evading capture was a record for downed airmen during the war. USAF General John W. Vogt, Jr., commanding general of the Seventh Air Force, "shut down the war" and sent 119 aircraft to recover him. His rescue was the deepest inside North Vietnam during the entire War. When his aircraft, F-4D, AF Ser. No. 65-0784, was shot down by a Shenyang J-6 on May 10, 1972, Locher was on his third combat tour and had over 407 combat missions. He was one of the leading MiG killers in Vietnam with three aerial victories. No one saw him eject or his parachute open, and it was unknown whether he had died or been captured. Over the next two weeks, U.S. air cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OCLC
OCLC, Inc. See also: is an American nonprofit cooperative organization "that provides shared technology services, original research, and community programs for its membership and the library community at large".

G-suit
A g-suit, or anti-''g'' suit, is a flight suit worn by aviators and astronauts who are subject to high levels of acceleration force ( g). It is designed to prevent a black-out and g-LOC (g-induced loss of consciousness) caused by the blood pooling in the lower part of the body when under acceleration, thus depriving the brain of blood. Black-out and g-LOC have caused a number of fatal aircraft accidents. Operation If blood is allowed to pool in the lower areas of the body, the brain will be deprived of blood. This lack of blood flow to the brain first causes a greyout (a dimming of the vision also called brownout), followed by tunnel vision and ultimately complete loss of vision 'blackout' followed by g-induced Loss Of Consciousness or 'g-LOC'. The danger of g-LOC to aircraft pilots is magnified because on relaxation of g-force there is a period of disorientation before full sensation is re-gained. A g-suit does not so much increase the g-threshold, but makes it possible to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bosnia
Bosnia and Herzegovina, sometimes known as Bosnia-Herzegovina and informally as Bosnia, is a country in Southeast Europe. Situated on the Balkans, Balkan Peninsula, it borders Serbia to the east, Montenegro to the southeast, and Croatia to the north and southwest, with a coast on the Adriatic Sea in the south. Bosnia (region), Bosnia has a moderate continental climate with hot summers and cold, snowy winters. Its geography is largely mountainous, particularly in the central and eastern regions, which are dominated by the Dinaric Alps. Herzegovina, the smaller, southern region, has a Mediterranean climate and is mostly mountainous. Sarajevo is the capital and the largest city. The area has been inhabited since at least the Upper Paleolithic, with permanent human settlement traced to the Neolithic cultures of Butmir culture, Butmir, Kakanj culture, Kakanj, and Vučedol culture, Vučedol. After the arrival of the first Proto-Indo-Europeans, Indo-Europeans, the area was populated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott O'Grady
Scott Francis O'Grady (born October 12, 1965) is a former United States Air Force (USAF) fighter pilot. On June 2, 1995, he was shot down over Bosnia and Herzegovina by a 2K12 Kub (NATO designation SA-6 "Gainful") mobile surface-to-air missile (SAM) and forced to eject from his F-16C into hostile territory. US Marines from heavy-helicopter squadron HMH-464 and the 24th Marine Expeditionary Unit eventually rescued O'Grady after six days of evading the Bosnian Serbs. He was previously involved in the Banja Luka incident when he had fired upon six enemy aircraft. The 2001 film '' Behind Enemy Lines'' is loosely based on his experience. In September 2011, O'Grady announced a run for the 2012 Republican nomination for Texas State Senate District 8 seat, held at the time by the retiring Republican Florence Shapiro, In January 2012, he suspended his campaign "due to the uncertainty of a primary election date from redistricting." In November 2020, President Donald Trump stated an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean Current
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents move both horizontally, on scales that can span entire oceans, as well as vertically, with vertical currents (upwelling and downwelling) playing an important role in the movement of nutrients and gases, such as carbon dioxide, between the surface and the deep ocean. Ocean currents flow for great distances and together they create the global conveyor belt, which plays a dominant role in determining the climate of many of Earth's regions. More specifically, ocean currents influence the temperature of the regions through which they travel. For example, warm currents traveling along more temperate coasts increase the temper ...

Survival Radio
Survival radios are carried by pilots and search and rescue teams to facilitate rescue in an emergency. They are generally designed to transmit on international distress frequencies. Maritime systems have been standardized under the Global Maritime Distress Safety System. Civil and military organisations utilized different frequencies to communicate and no infringement on either sector would take place. For emergencies involving civilian aircraft, the radio frequency used is VHF 121.5 MHz and for military aircraft incidents, the frequency used is UHF 243 MHz. History The use of radio to aid in rescuing survivors of accidents at sea came to the forefront after the sinking of the RMS ''Titanic'' in 1912. Lifeboats were equipped with spark gap transmitters such as the Marconi Type 241, c. 1920. These operated using Morse code on 500 kHz, the international distress frequency at the time. This frequency had the advantage of long range due to ground-wave propagation and was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celestial Pole
The north and south celestial poles are the two points in the sky where Earth's axis of rotation, indefinitely extended, intersects the celestial sphere. The north and south celestial poles appear permanently directly overhead to observers at Earth's North Pole and South Pole, respectively. As Earth spins on its axis, the two celestial poles remain fixed in the sky, and all other celestial points appear to rotate around them, completing one circuit per day (strictly, per sidereal day). The celestial poles are also the poles of the celestial equatorial coordinate system, meaning they have declinations of +90 degrees and −90 degrees (for the north and south celestial poles, respectively). Despite their apparently fixed positions, the celestial poles in the long term do not actually remain permanently fixed against the background of the stars. Because of a phenomenon known as the precession of the equinoxes, the poles trace out circles on the celestial sphere, with a period ...

Olefin Fiber
Olefin fiber is a synthetic fiber made from a polyolefin, such as polypropylene or polyethylene. It is used in wallpaper, carpeting, ropes, and vehicle interiors. Olefin's advantages are its strength, colorfastness and comfort, its resistance to staining, mildew, abrasion, and sunlight, and its good bulk and cover. History Italy began production of olefin fibers in 1957. The chemist Giulio Natta successfully formulated olefin suitable for more textile applications. Both Natta and Karl Ziegler were later awarded the Nobel Prize for their work on transition metal catalysis of olefins to fiber, also known as Ziegler–Natta catalysis. Production of olefin fibers in the U.S. began in 1960. Olefin fibers account for 16% of all manufactured fibers. Major fiber properties Olefin fibers have great bulk and cover while having low specific gravity. This means “Warmth without the weight.” The fibers have low moisture absorption, but they can wick moisture and dry quickly. Olefin ...

Spunbond
Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam. Applications Because nonwoven fabrics do not require the intermediate step of converting fibres to yarn, they have more flexibility in materials usage. Nonwoven fabrics may be single-use, have a limited life, or be very durable. Nonwoven fabrics are sometimes designed to provide specific functions such as absorbency, liquid repellence, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, thermal insulation, acoustic insulation, filtration, use as a bacterial barrier ...
