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.
Bridgehampton Race Circuit
Bridgehampton Race Circuit was a race track located near Sag Harbor, New York, United States. The circuit opened in 1957, following a series of road races held from 1949 until 1953. It was one of the first permanent road racing venues in the United States, opening after Thompson Speedway, two years after Road America, the year after Watkins Glen International, and the same year as Lime Rock Park and Laguna Seca Raceway. In its early years, Bridgehampton was host to major international series, including the World Sportscar Championship, Can-Am, and NASCAR Grand National. By the early 1970s, the track was used mostly for amateur events. From its opening day to the mid 90's the AMA (Championship Cup Series in the 90's) hosted events twice a month and was a favorite to many motorcycle road racers. The track closed permanently in 1998.
