Dangerous Sports Club
The Dangerous Sports Club was a group of adventurers and extreme sports pioneers based in Oxford and London, England. They were active from the late 1970s for about ten years, during which they developed modern bungee jumping and experimented with a variety of other innovative sporting activities. Origins The Dangerous Sports Club was co-founded by David Kirke, Chris Baker, Ed Hulton and Alan Weston in the 1970s. They first came to wide public attention by inventing modern day bungee jumping, by making the first modern jumps on 1 April 1979, from the Clifton Suspension Bridge, Bristol, England. They followed the Clifton Bridge effort with a jump from the Golden Gate Bridge in San Francisco (including the first female bungee jump by Jane Wilmot), and with a televised leap from the Royal Gorge Suspension Bridge in Colorado, sponsored by and televised on the popular American television program ''That's Incredible!'' Initially, bungee jumping was a niche novelty; it was popularised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Double-decker Bus
A double-decker bus is a bus that has two storeys or decks. Double-deckers are used primarily for commuter transport, but open-top models are used as sightseeing buses for tourists, and there are coaches too for long-distance travel. They appear in many places around the world but are presently most commonly used as mass transport in cities of Britain, and in Ireland, China, Hong Kong, Berlin and Singapore. The earliest double-decker horse-drawn omnibus appeared in Paris in 1853 and such vehicles were motorised in the 1900s. Double-decker buses were popularised in Great Britain at the start of the 20th century and today the best-known example is the red London bus, namely the AEC Routemaster. Double-deckers in urban transport were also in common use in other places, such as major cities of India, but were mostly diminished or phased out by the end of the 20th century. However they remain common in Britain as well as Ireland and Hong Kong, while in Singapore and Dhaka they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frenchay Hospital
Frenchay Hospital was a large hospital in Frenchay, South Gloucestershire, on the north east outskirts of Bristol, England, which closed in 2014. It was managed by North Bristol NHS Trust. From April to December 2014, most of Frenchay Hospital was progressively closed, with the majority of services moving to a new building at Southmead Hospital. Accident and Emergency was transferred on 19 May 2014. Child services moved to the Bristol Royal Hospital for Children. Services relating to brain and head injuries remained at the site and later moved into a newly built clinic. History Early history The hospital, situated in the grounds of a Georgian architecture, Georgian mansion, Frenchay Park, started life as a tuberculosis hospital (Frenchay Park Sanatorium) in 1921, when History of local government in Bristol, Bristol Corporation acquired the land. In 1931, five purpose-built buildings were constructed to extend the hospital beyond the original house. Concerns about the possibilit ...

Trebuchet
A trebuchet () is a type of catapult that uses a hinged arm with a sling attached to the tip to launch a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than a traditional catapult. There are two main types of trebuchet. The first is the ''traction trebuchet'', or mangonel, which uses manpower to swing the arm. It first appeared in China by the 4th century BC. It spread westward, possibly via the Avars, and was adopted by the Byzantines, Persians, Arabs, and other neighboring peoples by the sixth to seventh centuries AD. The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim lands around the Mediterranean in the 12th century, and was carried back to China by the Mongols in the 13th century. "Although this is ...

BASE Jumping
BASE jumping () is the recreational sport of jumping from fixed objects, using a parachute to descend to the ground. BASE is an acronym that stands for four categories of fixed objects from which one can jump: buildings, antenna (radio), antennas (referring to radio masts and towers, radio masts), span (engineering), spans (bridges) and earth (cliffs). Participants jump from a fixed object such as a cliff and after an optional freefall delay deploy a parachute to slow their descent and land. A popular form of BASE jumping is Wingsuit flying#Wingsuit_BASE, wingsuit BASE jumping. In contrast to other forms of parachuting, such as skydiving from airplanes, BASE jumps are performed from fixed objects that are generally at much lower altitudes, and BASE jumpers only carry one parachute. BASE jumping is significantly more hazardous than other forms of parachuting and is widely considered to be one of the most dangerous extreme sports.

Magma
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma (sometimes colloquially but incorrectly referred to as ''lava'') is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and volcanic gas, gas bubbles. Magma is produced by melting of the mantle (geology), mantle or the Crust (geology), crust in various tectonics, tectonic settings, which on Earth include subduction zones, continental rift (geology), rift zones, mid-ocean ridges and Hotspot (geology), hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal mush, crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by Fractional crystallization (geology), fractional crystallization, contaminati ...

Surfing
Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found as standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or wave pools. Surfing includes all forms of wave-riding using a board, regardless of the stance. There are several types of boards. The Moche of Peru would often surf on reed craft, while the native peoples of the Pacific surfed waves on alaia, paipo, and other such watercraft. Ancient cultures often surfed on their belly and knees, while modern-day surfing is most often ''stand-up surfing'', in which a surfer rides a wave while standing on a surfboard. Another prominent form of surfing is body boarding, where a surfer rides the wave on a bodyboard, either lying on thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microlight
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 shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zorbing
Zorbing (also known as globe-riding, sphereing, orbing) is the recreation or sport of rolling downhill inside an orb, typically made of transparent plastic. Zorbing is generally performed on a gentle slope but can also be done on a level surface, permitting more rider control. In the absence of hills, some operators have constructed inflatable, wooden, or metal ramps. Due to the buoyant nature of the orbs, Zorbing can also take place on water, provided the orb is inflated properly and sealed once the rider is inside. " Water walking" using such orbs has become popular in theme parks across the UK. There are two types of orbs: harnessed and non-harnessed. Non-harnessed orbs carry up to three riders, while the harnessed orbs are constructed for one to two riders. The first zorbing site was established in Rotorua, New Zealand, by ZORB Ltd. History A Russian article on the Zorb mentions a similar device having debuted in 1973. In the early 1980s, the Dangerous Sports Club constr ...

Volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is str ...

Hang Gliding
Hang gliding is an air sports, air sport or recreational activity in which a pilot flies a light, non-motorised, fixed-wing aircraft, fixed-wing heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or Composite material, composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to Lift (soaring), soar for hours, gain thousands of meters of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the sa ...

Pilot Licensing And Certification
Pilot licensing or certification refers to permits for operating aircraft. Flight crew licences are issued by the civil aviation authority of each country, which must establish that the holder has met minimum knowledge and experience before issuing licences. The licence, along with the required class or type rating, allows a pilot to fly aircraft registered in the licence issuing state. Regulators The International Civil Aviation Organization's "Annex 1 – Personnel Licensing" acts as the international minimum standard for licensing. However, states can deviate from these standards by notifying ICAO about the changes. In the United States, pilot certification is regulated by the Federal Aviation Administration (FAA), a branch of the U.S. Department of Transportation (DOT). A pilot is certified under the authority of Parts 61 and 141 of Title 14 of the Code of Federal Regulations, also known as the Federal Aviation Regulations (FARs).
