Hradčany Air Base
Hradčany Airport (in Czech ''Letiště Hradčany'', often ''Letiště Ralsko'') is a former military airport within the area of Ralsko in Liberec Region, northern Czech Republic. Built toward the end of World War II for the Luftwaffe, it was expanded after the war. In 1968 the Soviet Army took control and set up a large air base here. However, after the Soviets left in 1991, the airport was abandoned and it is now neglected and damaged. History The area was used for military training during Austria-Hungary and during the First Republic of Czechoslovakia. Since 1938 the area was controlled by the ''Wehrmacht'' and used for training. In March 1945 the ''Wehrmacht'' built a field airport next to village Hradčany (''Kummer''). By April 1945 Stab and II./SG 2 of Luftwaffe's Schlachtgeschwader 2 were based here, while its I./SG 2 was in Austria, and III./SG 2 near Prague. The airport was also used by a wing of Messerschmitt Me 262 at the end of the war, and later damaged by American ... [...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] |
Mig-21
The Mikoyan-Gurevich MiG-21 (russian: Микоян и Гуревич МиГ-21; NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. Its nicknames include: "balalaika", because its planform resembles the stringed musical instrument of the same name; "''Ołówek''", Polish for "pencil", due to the shape of its fuselage, and "''Én Bạc''", meaning "silver swallow", in Vietnamese. Approximately 60 countries across four continents have flown the MiG-21, and it still serves many nations six decades after its maiden flight. It set aviation records, becoming the most-produced supersonic jet aircraft in aviation history, the most-produced combat aircraft since the Korean War and, previously, the longest production run of any combat aircraft (now exceeded by both the McDonnell Douglas F-15 Eagle and General Dynamics F-16 Fighting Falcon). Development Origins The MiG-21 jet fight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In The Liberec Region
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rave Party
A rave (from the verb: '' to rave'') is a dance party at a warehouse, club, or other public or private venue, typically featuring performances by DJs playing electronic dance music. The style is most associated with the early 1990s dance music scene when DJs played at illegal events in musical styles dominated by electronic dance music from a wide range of sub-genres, including techno, hardcore, house, and alternative dance. Occasionally live musicians have been known to perform at raves, in addition to other types of performance artists such as go-go dancers and fire dancers. The music is amplified with a large, powerful sound reinforcement system, typically with large subwoofers to produce a deep bass sound. The music is often accompanied by laser light shows, projected coloured images, visual effects and fog machines. While some raves may be small parties held at nightclubs or private homes, some raves have grown to immense size, such as the large festivals and events f ...

Ultralight Aviation
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jamboree
In Scouting, a jamboree is a large gathering of Scouting, Scouts who rally at a national or international level.

Junák
Junák – český skaut (''Junák – Czech Scouting''), is the internationally recognized organization of Scouts and Guides of the Czech Republic. Founded in 1911, Junák – český skaut is the largest organisation of children and youth in the nation, with a membership of 73,315 (as of 2022). History A voluntary, non-political civic organization, without restriction to membership, Junák was founded in 1911 by Antonín Benjamin Svojsík, who, after visiting British Scouts, wanted to establish a similar movement in his homeland. In 1910, inspired by the writings of Baden-Powell, Svojsík wrote ''Základy junáctví'' ("The Foundations of Scouting"), the first handbook for Scouts already operating in the Czech lands. In that book, he combined Baden-Powell's system of education; ideas of the American writer, traveller and painter Ernest Thompson Seton (founder of Woodcraft); and the traditions of the Czech nation. He followed this with an experimental camp in 1912. The partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-cost Carrier
A low-cost carrier or low-cost airline (occasionally referred to as '' no-frills'', ''budget'' or '' discount carrier'' or ''airline'', and abbreviated as ''LCC'') is an airline that is operated with an especially high emphasis on minimizing operating costs and without some of the traditional services and amenities provided in the fare, resulting in lower fares and fewer comforts. To make up for revenue lost in decreased ticket prices, the airline may charge extra fees – such as for carry-on baggage. As of April 2020, the world's largest low-cost carrier is Southwest Airlines, which operates primarily in the United States, as well as in some surrounding areas. The term originated within the airline industry referring to airlines with a lower operating cost structure than their competitors. While the term is often applied to any carrier with low ticket prices and limited services, regardless of their operating models, low-cost carriers should not be confused with regional airl ...
