Minami Torishima Airport
is a one runway airport serving the island of Minami Torishima, Japan. The aerodrome used to be a military airstrip and according to the Japanese Aeronautical Information Service, is still operated by the Japan Maritime Self-Defense Force. The airstrip existence dates to 1935 when the Imperial Japanese Navy built one to serve a meteorological station. The original airfield consisted of two airstrips (cleared area of 4000' and 4500', but only shorter sections used as landing area) in a v-shaped formation. The airstrips facilities were damaged by US bombing of the island during World War II, and was re-built with a single runway by the United States Naval Mobile Construction Battalion 9 in 1964. Until 1993, the airstrip was used and controlled by the United States Coast Guard to service the nearby LORAN-C station. In 2009 the airstrip was transferred to the Japan Maritime Self-Defense Force which currently retains control of the airstrip and is used by the Japan Meteorological ...

Minami Torishima
, also known as Marcus Island, is an isolated Japanese coral atoll in the northwestern Pacific Ocean, located some southeast of Tokyo and east of the closest Japanese island, South Iwo Jima of the Ogasawara Islands, and nearly on a straight line between mainland Tokyo and Wake Island, further to the east-southeast. The closest island to Minamitorishima is East Island in the Mariana Islands, which is to the west-southwest. It is the easternmost territory belonging to Japan, and the only Japanese territory on the Pacific Plate, past the Japan Trench. Although small () it is of strategic importance, as it enables Japan to claim a exclusive economic zone in the surrounding waters. It is also the easternmost territory of Tokyo, being administratively part of Ogasawara village. There is no civilian population, except personnel of the Japan Meteorological Agency, JSDF, and Japan Coast Guard serving temporary tours of duty on the island. Access The island is off-limits to civilia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronautical Information Publication
In aviation, an Aeronautical Information Publication (or AIP) is defined by the International Civil Aviation Organization as a publication issued by or with the authority of a state and containing aeronautical information of a lasting character essential to air navigation. It is designed to be a manual containing thorough details of regulations, procedures and other information pertinent to flying aircraft in the particular country to which it relates. It is usually issued by or on behalf of the respective civil aviation administration. Overview The structure and contents of AIPs are standardized by international agreement through ICAO. AIPs normally have three parts – GEN (general), ENR (en route) and AD (aerodromes). The document contains many charts; most of these are in the AD section where details and charts of all public aerodromes are published. AIPs are kept up-to-date by regular revision on a fixed cycle. For operationally significant changes in information, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
