In vehicle acrobatics, a wheelie, or wheelstand, is a vehicle maneuver in which the front wheel or wheels come off the ground due to sufficient torque being applied to the rear wheel or wheels, or rider motion relative to the vehicle. Wheelies are associated with bicycles and motorcycles, but can be done with other vehicles such as cars in drag racing and tractor pulling; the first wheelie was done in 1890 by trick bicyclist Daniel J. Canary, shortly after modern bicycles became popular. Wheelies appear in popular culture as early as 1943, as U. S Army motorized cavalry are pictured in Life magazine performing high speed wheelies. Daredevil Evel Knievel performed motorcycle acrobatics including wheelies in his shows. Doug "The Wheelie King" Domokos has accomplished such feats as a 145-mile wheelie. Types of wheelie can be divided into two broad categories: 1. Wheelies in which the vehicle power is sufficient by itself, as described in the Physics section below; these include: Clutch wheelies: performed by revving the engine with the clutch disengaged, abruptly engaging the clutch.

Power wheelies or roll-on wheelies: performed by opening the throttle. If the engine has sufficient power, it will be able to lift the front wheel.2. Wheelies performed with the aid of rider motion; these include: Bounce wheelies or slap wheelies: performed by opening and closing the throttle in time with suspension rebounding, tire rebounding, rider motion, or any combination of the three. Manuals: performed without applying torque to the rear wheel at all, but instead by moving the rider's body backwards relative to the bike, pulling back on the handlebars near the end of available travel. Wheelies are a common stunt in artistic cycling and freestyle BMX; the bike is balanced by the rider's weight and sometimes use of the rear brake. A style of bicycle, the wheelie bike, has a seating position, thus center of mass, nearly over the rear wheel that facilitates performing wheelies. A wheelie is a common motorcycle stunt; the principle is the same as the bicycle wheelie, but the throttle and rear brakes are used to control the wheelie while a rider uses body weight and the steering to control the direction the inertia of the spinning front wheel acting as a balance.

The world's fastest motorcycle wheelie record is 307.86 km/h by Patrik Furstenhoff. April 18, 1999; the world record for the fast wheelie over 1 km is 343.388 km/h, set by Egbert van Popta at Elvington airfield in Yorkshire, England. In some countries, such as the United Kingdom and USA, motorcyclists performing a wheelie on a public road may be prosecuted for dangerous driving, an offense which can carry a large fine and a ban of a year or more. In Pakistan and some other countries, it is illegal to perform these kinds of stunts. If someone is caught performing these acts, the rider can have their motorcycle impounded and face jail time. Wheelies are common in auto- or motorcycle drag racing, where they represent torque wasted lifting the front end, rather than moving the vehicle forward, they usually result in raising the center of mass, which limits the maximum acceleration. In the absence of wheelie bars, this effect is quantified in the physics section below. If wheelie bars are present a wheelie results in a reduction of load on the rear driving wheels, along with a corresponding reduction in friction.

Wheelies are possible with some snowmobiles. Some wheelchair users can learn to do a wheelie; this enables them to descend curbs and maneuver over small obstacles. Wheelchair dancers perform wheelies. In an airplane, a wheelie is performed by conducting take-off procedure; the pilot increases the elevator backpressure so the nose wheel of the landing gear has minimal contact with the ground. On 14 February 2020, the Guinness World Record for the longest-distance wheelie in an airplane was set in a Cessna 172 at Southern California Logistics Airport in Victorville, California on its runway 17; the pilot kept the plane's nose wheelie from touching the asphalt surface for a distance of 14,319 feet. Wheelie bars help prevent a vehicle's front end from flipping over. Wheelie bars are required for some truck pull events. Wham-O sold an add-on wheelie bar for wheelie bikes. On September 25, 2016, British trials motorcyclist Dougie Lampkin wheelied around the Isle of Man TT course, he completed the challenge in one hour and 35 minutes, after the attempt was postponed 24 hours because of strong winds.

A wheelie is imminent when the acceleration is sufficient to reduce the load borne by the front axle to zero. The conditions for this can be calculated with the so-called "weight transfer equation": Δ W e i g h t f r o n t = a h w m where Δ W e i g h t f r o n t is the change in load borne by the front wheels, a is the longitudinal acceleration, h is the center of mass height, w is the wheelbase, m is the total vehicle mass. An equivalent expression, which does not require knowing the load borne by the front wheels nor the total vehicle mass, is for the minimum longitudinal

Fort Lee Air Force Station

Fort Lee Air Force Station is a closed United States Air Force station. It is located 2.9 miles northwest of Virginia. It was closed in 1983. Fort Lee Air Force Station, located on the United States Army Fort Lee installation, was selected in 1956 for a Semi Automatic Ground Environment system direction center site, designated DC-04; the SAGE system was a network linking Air Force General Surveillance Radar stations into a centralized center for Air Defense, intended to provide early warning and response for a Soviet nuclear attack. This automated control system was used by NORAD for intercepting enemy bomber aircraft. In the versions the system could automatically direct aircraft to an interception by sending instructions directly to the aircraft's autopilot; the 4625th Air Defense Wing was activated at the site under the 85th Air Division on 1 December 1956 to supervise the construction of the SAGE blockhouses and the installation and testing of the SAGE electronic and data processing equipment.

The 4625th ADW was re-designated as the Washington Air Defense Sector on 8 January 1957 upon DC-04's activation, remaining under the 85th AD. The operation of the Semi Automatic Ground Environment direction center was the mission the WaADS; the Sector was disestablished on 1 April 1966, the SAGE operations were reassigned to the 33d Air Division, being moved to Fort Lee AFS from Richards-Gebaur AFB, Missouri. The 33d AD was inactivated on 19 November 1969, its assets being assumed by the newly reactivated 20th Air Division at Fort Lee AFS The DC-04 and the 20th Air Division were inactivated on 1 March 1983 by Air Defense, Tactical Air Command. With its inactivation, Fort Lee Air Force Station was closed. After its closure, the site was taken over by other Federal Government agencies, is now houses several such offices. Only the orderly room, mess hall and one barracks building still stand of the Air Force station; the SAGE blockhouse stands, now named Von Steuben Hall, it contains the U. S. Army Communications-Electronics Command Software Engineering Center - Lee.

Ciudad Nezahualc├│yotl

Nezahualcóyotl, or more Neza, is a city and municipality of State of Mexico adjacent to the northeast corner of Mexico City: it is thus part of the Mexico City Metropolitan Area. It was named after Nezahualcoyotl, the Acolhua poet and king of nearby Texcoco, was built on the drained bed of Lake Texcoco; the name Nezahualcóyotl comes from Nahuatl, meaning "fasting coyote."Until the 20th century, the land on which Ciudad Neza sits was under Lake Texcoco and uninhabited. Successful draining of the lake in the early 20th century created new land, which the government sold into private hands. However, public services such as adequate potable water and sewerage were lacking until after the area was made an independent municipality in 1963. Today Ciudad Neza is a sprawling city of over one million with modern buildings; as of 2006, Nezahualcóyotl included part of the world's largest mega-slum, along with Chalco and Izta. Most of its population have migrated from other parts of Mexico, it has a high crime rate, in part due to "cholos" or gangs formed since the 1990s based on gang models in the United States Los Angeles.

Since the 2000s, a significant number of natives of this city have immigrated to the United States settling in New York. This has led to a new Mexican subculture in the area; the city and municipality is named after the Aztec King Nezahualcóyotl. The entity has an Aztec glyph as well as a coat of arms; the glyph depicts the head of a coyote, tongue outside the mouth with a collar or necklace as a symbol of royalty. It was one of the ways of depicting the Aztec king; the current coat of arms, which includes the glyph, was authorized by the municipality in the 1990s. The municipality comprises its own intrastate region, Region IX. Nezahualcoyotl, for whom the city and municipality were named, was the lord of Texcoco, one of the allies of the Aztec Triple Alliance. Texcoco dominated the area. Drainage of the interconnected lakes of the Valley of Mexico began in the early colonial period; the first major drainage project was begun in 1590, with the aim of eliminating the chronic flooding that plagued Mexico City.

By the time of the Mexican War of Independence, flooding was still a problem in the Mexico City area, at that time a project was begun to drain Lake Texcoco directly. The Lake Texcoco area was declared federal property in 1912, after which efforts to drain the lake commenced which continued until the 1930s. Starting in 1917 under Venustiano Carranza, efforts to determine legal ownership of lands that began to appear due to the drainage of the lake were undertaken. Most of this land was declared federal property to be sold. In 1933, the Mexico City–Puebla highway was built through this area; the first settlements in what is now the municipality were extensions of the municipalities of Chimalhuacán, La Paz and Ecatepec. The area was known for a bird species called the chichicuilote-atziztizuilotl, which inhabited the lakes and ponds of the Valley of Mexico. Today it is nearly extinct; the center of the city had an area that specialized in the sale of the bird, both cooked. These initial settlements were without infrastructure or public services, efforts to procure these began in the 1940s.

In 1945 the Xochiaca dam and the Tequixquiac tunnel were built, the diversion of potable water allowed for the creation of the first formal neighborhoods of Juárez Pantitlán, México and El Sol. By 1949, the area had 2,000 inhabitants. In the 1950s the population of the area grew as people from various parts of Mexico immigrated to the Mexico City area in search of opportunity; this grew to 40,000 despite of the lack of other services such as electricity. The area gained more formal administrative status from the state of Mexico in the 1950s as it grew, but by 1959, a group representing the now-33 neighborhoods of the area protested the lack of services, which still included sufficient potable water. In 1960, the idea emerged to separate this area from the municipality of Chimalhuacán in order to create a new municipality. By this time, the area had a population of 80,000; this idea culminated into the creation of the municipality of Nezahualcóyotl on 3 April 1963 by the state legislature, with Jorge Sáenza Gómez Knoth as the first municipal president.

Conversion of the area into a municipality helped in getting water, pavement and streetlights in the 1960s and 1970s. However, the sale of land here was complicated due to problems in land title; this began to be regulated in the mid-1970s and would continue through the 1980s and into part of the 1990s. By the early 1980s, major public buildings such as hospitals, the municipal palace, schools and the Museum of Archeology had been built; the Xochiaca area had become a landfill with a sports facility built along its edge. The city grew during the 1980s with new neighborhoods, shopping centers and other urban areas built, it became necessary to have a municipal committee dedicated to the control of urban growth. In the 1990s the Ciudad Deportivo and the Universidad Tecnológica de Nezahualcóyotl were established; the population surpassed one million by 1995. The city has produced a number of athletes, such as Humberto "La Chiquita" González and Graciela Hernández, the first of many wheelchair basketball gold medalists in the Pan American Games.

The city is looked down upon by the residents of Mexico City proper, calling it "mi-Nezota" or "Neza York," which refers to its sprawling size, urban atmosphere devoid of the colonial structures in the center of town. Trash collect
