Silverstone Circuit
The Silverstone Circuit is a motor racing circuit in Northamptonshire and Buckinghamshire, England, named after the village in the former. It is best known as the home of the British Grand Prix, which it first hosted in 1948 and which has been held on the circuit every year since 1987. The circuit is also home to the BRDC International Trophy, formerly one of the premier non-Championship F1 races in the calendar, today awarded to the winner of a race for historic F1 cars at the annual Silverstone Classic meeting.

Circuit development
Half the circuit is in Northamptonshire and half in Buckinghamshire, roughly equidistant from Milton Keynes and Northampton. It is built on the site of a World War II bomber base, RAF Silverstone, which opened in 1943. The airfield's three runways, in classic WWII triangle format, lie within the outline of the present track.
Silverstone was first used for motorsport by an ad hoc group of friends who set up an impromptu race in September 1947. One of their number, Maurice Geoghegan, lived in nearby Silverstone village and was aware that the airfield was deserted. He and eleven other drivers raced over a two mile circuit, during the course of which Geoghegan himself was unfortunate enough to run over an errant sheep that had wandered onto the airfield. Both car and sheep were written off, and in the aftermath of this event the informal race became known as the Mutton Grand Prix.
The next year the Royal Automobile Club took a lease on the airfield and set out a more formal racing circuit. Their first two races were held on the runways themselves, with long straights separated by tight hairpin corners, the track demarcated by hay bales. However, for the 1949 International Trophy meeting, it was decided to switch to the perimeter track. This arrangement was used for the 1950 and 1951 Grands Prix. In 1952 the start line was moved from the Farm Straight to the present Finish Straight, and this layout remained largely unaltered for the following 35 years. For the 1975 meeting a chicane was introduced to try and tame speeds through the mighty Woodcote Corner, and Bridge Corner was subtly rerouted in 1987 before the track underwent a major redesign between the 1990 and 1991 races. The reshaped track's first F1 race was perhaps the most memorable of recent years, with Nigel Mansell coming home first in front of his home crowd. On his victory lap back to the pits Mansell even found time to pick up stranded rival Ayrton Senna and give him a lift on his side-pod, after Senna's McLaren had expired towards the end of the race.
Following the deaths of Senna and fellow Grand Prix driver Roland Ratzenberger at Imola in 1994, many Grand Prix circuits were modifed in order to reduce speed and increase driver safety. As a consequence of this the entry from Hangar Straight into Stowe Corner was modified in 1995 so as to make its entry less dangerous and, as a result, less challenging, and the flat-out Abbey kink was modified to a chicane in just 19 days before the 1994 GP.
Spectator traffic management
Historically Silverstone has suffered traffic jams on race days. This problem has been largely eliminated with the completion of the A43 Silverstone bypass, a dual-carriageway road just to the north of the circuit. When the race was moved to an April date in 2000, rainy conditions turned the fields used for car parking into mud baths, causing chaos for spectators trying to park.[3] On F1 race day a large number of spectators travel to the circuit by helicopter: enough to make Silverstone Heliport the busiest airport in the UK for this day.
