[Q]: Information: - The land speed record (or absolute land speed record) is the highest speed achieved by a person using a vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used, officiated by regional or national organizations under the auspices of the Federation Internationale de l'Automobile. The land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes"). Two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least one percent to be validated. There are numerous other class records for cars; motorcycles fall into a separate class. - The Federation Internationale de l'Automobile (FIA, English: International Automobile Federation) is an association established as the "Association Internationale des Automobile Clubs Reconnus" (AIACR, English: 'International Association of Recognized Automobile Clubs') on 20 June 1904 to represent the interests of motoring organisations and motor car users. To the general public, the FIA is mostly known as the governing body for many auto racing events. The FIA also promotes road safety around the world. - Charles Raymond Keech (born May 1, 1900 in Coatesville, Pennsylvania - June 15, 1929) was a board track and brick track racer in the 1920s.

White of Philadelphia ( unrelated to the White Motor Company ) , wanted to take the land speed record from the British , then shared in a duel between Henry Segrave and Malcolm Campbell . No suitable engines were available to give a sufficient advantage over the British Napier Lion , so the simplest possible chassis was constructed and three war - surplus Liberty aero engines were squeezed into it . The vehicle was so simple it had no clutch or gearbox and only a single fixed ratio . Once started by a push start , it had to keep rolling . Driver comforts were minimal : the forward engine was sheathed in a crude attempt at streamlining , the two side - by - side behind were bare , with the driver perched between them and the one in front . - Coatesville is a city in Chester County, Pennsylvania, United States. The population was 13,100 at the 2010 census. Coatesville is approximately 39 miles west of Philadelphia. It developed along Lancaster Turnpike, beginning in the late 18th century.

[Q]: Information: - Broadsiding is the method used in motorcycle speedway for travelling round the bends on the speedway track. The rider skids his rear wheel by spinning it at such a speed that it sets up a gyroscopic action and this opposes the natural tendencies of centrifugal force. Then he controls the slide by throttle control to maintain, increase or decrease the rate of which the rear wheel spins. Motorcycle speedway bikes have no brakes or suspension. The rider can scrub-off speed while still providing the drive to power the bike forward and around the bend. - Motorcycle speedway, usually referred to as speedway, is a motorcycle sport involving four and sometimes up to six riders competing over four anti-clockwise laps of an oval circuit. Speedway motorcycles use only one gear and have no brakes; racing takes place on a flat oval track usually consisting of dirt, loosely packed shale, or dolomite (mostly used in Australia and New Zealand). Competitors use this surface to slide their machines sideways, powersliding or broadsiding into the bends. On the straight sections of the track the motorcycles reach speeds of up to . - Motorcycle sport is a broad field that encompasses all sporting aspects of motorcycling. The disciplines are not all races or timed-speed events, as several disciplines test a competitor's various riding skills. - The Speedway Ekstraliga ( English : Polish Extraleague , Polish : Ekstraliga ulowa ) is the top division of motorcycle speedway in Poland .
