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.
2010 RAC Tourist Trophy
The 2010 RAC Tourist Trophy was an auto race held at the Silverstone Circuit, Northamptonshire and Buckinghamshire, Great Britain from 30 April–2 May. The event, the second round of the 2010 FIA GT1 World Championship season, was among the first to use the revised Arena layout of the Silverstone Circuit that was completed in early 2010. The GT1 series was part of the larger "Silverstone Supercar 2010" event, sharing the weekend with the FIA GT3 European Championship, GT4 European Cup, and the British Formula 3 Championship. The Championship race also served to award an annual champion for RAC Tourist Trophy, awarded by the Royal Automobile Club.
