Karl Wallenda was a German-American high wire artist. He was the founder of The Flying Wallendas, a daredevil circus troupe whose members performed dangerous stunts far above the ground, often without a safety net.
Tightrope walking, also called funambulism, is the skill of walking along a thin wire or rope. It has a long tradition in various countries and is commonly associated with the circus. Other skills similar to tightrope walking include slack rope walking and slacklining.
Jade Kindar-Martin is an American highwire walker and circus performer.
Philippe Petit is a French highwire artist who gained fame for his unauthorized highwire walks between the towers of Notre-Dame Cathedral in Paris in 1971 and of Sydney Harbour Bridge in 1973, as well as between the Twin Towers of the World Trade Center in New York City on the morning of 7 August 1974. For his unauthorized feat 400 metres above the ground – which he referred to as "le coup" – he rigged a 200-kilogram (440-pound) cable and used a custom-made 8-metre (30-foot) long, 25-kilogram (55-pound) balancing pole. He performed for 45 minutes, making eight passes along the wire.
A cage antenna is a radio antenna where a conventional design has been augmented by replacing a single long conductor with several parallel wires, connected at their ends, and held in position by ring spacers or support struts mounted on a central mast. The "cage" is either mounted around a central mast or suspended from overhead wires.
Canopy walkways – also called canopy walks, treetop walks or treetop walkways – provide pedestrian access to a forest canopy. Early walkways consisted of bridges between trees in the canopy of a forest; mostly linked up with platforms inside or around the trees. They were originally intended as access to the upper regions of ancient forests for scientists conducting canopy research. Eventually, because they provided only limited, one-dimensional access to the trees, they were abandoned for canopy cranes. Today they serve as ecotourism attractions in places such as Dhlinza Forest, KwaZulu-Natal, South Africa, Taman Negara National Park, Malaysia, Sedim River, Kulim, Nyungwe National Park, Rwanda and Kakum National Park, Ghana.
Slacklining is walking, running or balancing along a suspended length of flat webbing that is tensioned between two anchors. Slacklining is similar to slack rope walking and tightrope walking. Slacklines differ from tightwires and tightropes in the type of material used and the amount of tension applied during use. Slacklines are tensioned significantly less than tightropes or tightwires in order to create a dynamic line which will stretch and bounce like a long and narrow trampoline. Tension can be adjusted to suit the user, and different webbing may be used in various circumstances.
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.
A mast radiator is a radio mast or tower in which the metal structure itself is energized and functions as an antenna. This design, first used widely in the 1930s, is commonly used for transmitting antennas operating at low frequencies, in the LF and MF bands, in particular those used for AM radio broadcasting stations. The conductive steel mast is electrically connected to the transmitter. Its base is usually mounted on a nonconductive support to insulate it from the ground. A mast radiator is a form of monopole antenna.
The Liberty Building is located at 420 Main Street, across the Buffalo Metro Rail from Lafayette Square in Buffalo, New York, United States.
The Flying Wallendas is a circus act and group of daredevil stunt performers who perform highwire acts without a safety net. They were first known as The Great Wallendas, but the current name was coined by the press in the 1940s and has stayed since.
Aire-sur-la-Lys is a commune in the Pas-de-Calais department in northern France.
Carsluith Castle is a ruined tower house, dating largely to the 16th century. It is located beside Wigtown Bay in the historical county of Kirkcudbrightshire in Galloway, Scotland, around 4.8 kilometres (3.0 mi) south east of Creetown.
The Man Who Walked Between the Towers is an American children's picture book written and illustrated by the American author Mordicai Gerstein. Published in 2003, the book recounts the achievement of Philippe Petit, a French man who walked on a tightrope wire between the roofs of the twin towers of the World Trade Center in August 1974. Gerstein won the 2004 Caldecott Medal for his illustrations. The book has been adapted into a film and a ballet.
An umbrella antenna is a capacitively top-loaded wire monopole antenna, consisting in most cases of a mast fed at the ground end, to which a number of radial wires are connected at the top, sloping downwards. They are used as transmitting antennas below 1 MHz, in the MF, LF and particularly the VLF bands, at frequencies sufficiently low that it is impractical or infeasible to build a full size quarter-wave monopole antenna. The outer end of each radial wire, sloping down from the top of the antenna, is connected by an insulator to a supporting rope or cable anchored to the ground; the radial wires can also support the mast as guy wires. The radial wires make the antenna look like the wire frame of a giant umbrella hence the name.
The Red Road Flats were a mid-twentieth-century high-rise housing complex located between the districts of Balornock and Barmulloch in the northeast of the city of Glasgow, Scotland. The estate originally consisted of eight multi-storey blocks of steel frame construction. All were demolished by 2015. Two were "slabs", much wider in cross-section than they are deep. Six were "points", more of a traditional tower block shape. The slabs had 28 floors, the point blocks 31, and taken together, they were designed for a population of 4,700 people. The point blocks were among the tallest buildings in Glasgow at 89 metres (292 ft), second in overall height behind the former Bluevale and Whitevale Towers in Camlachie. The 30th floor of the point blocks were the highest inhabitable floor level of any building in Glasgow.
Nikolas Wallenda is an American acrobat, aerialist, daredevil, high wire artist, and author. He is known for his high-wire performances without a safety net. He holds 11 Guinness World Records for various acrobatic feats, and is best known as the first person to walk a tightrope stretched directly over Niagara Falls. Wallenda walked 1,800 feet (550 m) on a steel cable over Masaya Volcano in Nicaragua, his longest walk, on March 4, 2020.
In electronics and radio communication, a counterpoise is a network of suspended horizontal wires or cables, used as a substitute for an earth (ground) connection in a radio antenna system. It is used with radio transmitters or receivers when a normal earth ground cannot be used because of high soil resistance or when an antenna is mounted above ground level, for example, on a building. It usually consists of a single wire or network of horizontal wires, parallel to the ground, suspended above the ground under the antenna, connected to the receiver or transmitter's "ground" wire. The counterpoise functions as one plate of a large capacitor, with the conductive layers of the earth acting as the other plate.
Jim Moore is an American photographer who has documented the variety arts since the 1970s. His photographs helped Philippe Petit plan his tightrope-walking stunt between the Twin Towers of the World Trade Center in 1974 and were prominently featured in the Oscar-winning film Man on Wire.
The Walk is a 2015 American 3D biographical drama film directed by Robert Zemeckis and written by him and Christopher Browne. It is based on the story of 24-year-old French high-wire artist Philippe Petit's walk between the Twin Towers of the World Trade Center on August 7, 1974. The film stars Joseph Gordon-Levitt as Petit, alongside Ben Kingsley, Charlotte Le Bon, James Badge Dale, Ben Schwartz, and Steve Valentine.
