RAF Silverstone
Today the airfield is a major racing circuit known as Silverstone Circuit. The circuit hosted the first ever Formula One World Championship race, the 1950 British Grand Prix, held on 13 May 1950. Since 1987 the track has hosted the British Grand Prix every year. The airfield's three runways, in a standard World War II era triangle, lie within the outline of the classic racetrack; after recent development of a new section of track, the main runway is transected by the circuit. Sections of two runways are used for the smaller south circuit.
2000 Silverstone 500 USA Challenge
This event was the first American Le Mans Series race held outside of North America. It served as a precursor to the creation of the European Le Mans Series by gauging the willingness of European teams from the FIA Sportscar Championship and FIA GT Championship to participate in a series identical to the American Le Mans Series. This event also shared the weekend at Silverstone with an FIA GT round, with some GT teams running both events.
