Development history of Silverstone Circuit
Silverstone Circuit is built on the site of a World War II Royal Air Force bomber station, RAF Silverstone, which opened in 1943. The airfield's three runways, in classic WWII triangle format, lie within the outline of the present track. Since its first use in the 1940s, the circuit has undergone several changes. History. Silverstone Circuit was first used for motorsport by an "ad hoc" group of friends who set up an impromptu race in September 1947. One of their members, 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 ran over a sheep that had wandered onto the airfield. The sheep was killed and the car 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 straight linking Woodcote and Copse corners, and this layout remained largely unaltered for the following 38 years. For the 1975 meeting a chicane was introduced to try to tame speeds through the mighty Woodcote Corner (although MotoGP would still use the circuit without the chicane up until 1986). In 1987 Luffield a left right corner was added. The track  underwent a major redesign between the 1990 and 1991 races, transforming the ultra-fast track (where in its last years, every corner was taken in no lower than 4th or 5th gear – depending on the transmission of the car – except for the Bridge chicane, which was usually taken in 2nd gear) into a more technical track. The Maggotts, Becketts and Chapel corners were modified into a challenging and deeply rapid left-right-left-right-left sequence with Becketts being altered to create this section. A bridge was added to the hanger straight. Vale was added between Stowe and Club to  entice overtaking and new section of Bridge (named after the bridge which went across the track), Priory, Brooklands (named after the motor racing circuit), and a changed Luffield corners was added after Abbey. Following the deaths of Senna and fellow Grand Prix driver Roland Ratzenberger at Imola in 1994, many Grand Prix circuits were modified in order to reduce speed and increase driver safety. As a consequence of this, Copse, Stowe, Abbey and Priory corners were all re-profiled to be slower with increased run off. A chicane at Abbey was added for 1994 after Pedro Lamy's Lotus car  ended up in the pedestrian tunnel that passed under the bridge that preceded bridge corner during testing. In 1997 many corners were again re-profiled, but this time to increase the speed and flow of the circuit. Recent developments. Bernie Ecclestone stated that he would negotiate the future of Formula One at Silverstone post-2009 only if the BRDC gives up its role as promoter of the event. In an Autosport interview he said "I want to deal with a promoter rather than the BRDC. It is too difficult with the BRDC because you get no guarantees with them. We've  said that unless they can get the circuit to the level expected from so-called third-world countries we are not prepared to do a deal. They know what we want them to build." A new pit-and-paddock complex is the minimum redevelopment required. Maurice Hamilton has described the attitude of the BRDC as "[appearing to be] inflexible and sometimes arrogant". During testing ahead of the British Grand Prix, Damon Hill likened the relationship between the BRDC and governing body as that of Aladdin's Cave: "The genie says give me the lamp and Aladdin says get me out  of the cave and I’ll give you the lamp. You’re in this constant cycle whereby in order to get our plans implemented we need to have a Grand Prix contract, and in order to get the Grand Prix contract we have to have our planning." On 1 August 2007 it was announced that a £25m redevelopment of the circuit had been approved, with new grandstands, pit facilities and a development centre planned. However, on 4 July 2008 it was announced that the event would move to Donington Park from 2010. On 12 January 2009 it was  announced that Silverstone would host the British MotoGP from 2010 after signing a five-year deal to hold this event. On 18 February 2009, the first pictures of the MotoGP Layout emerged (this has since changed to the layout that was constructed). The track will be slightly longer than the Grand Prix circuit, as it uses parts of the three main configurations at Silverstone – the Grand Prix circuit from the start-finish to Abbey corner, then turns right to go up part of the International layout in reverse, before joining the National Circuit's straight from a left-hand hairpin  known as the "Arrowhead". Having negotiated the straight, the bikes will rejoin the Grand Prix circuit at Brooklands. On 20 June 2009 Bernie Ecclestone stated that there would be a British Grand Prix at Silverstone in 2010 if Donington was not ready to host it. When asked why he had moved from his previous "Donington or nothing" standpoint he cited changes in the structure of the BRDC meaning there was a better way of negotiating with them over future commercial rights. Furthermore during an interview with the BBC about the Formula One Teams Association threatening to break away and form  their own series, FIA president Max Mosley said it was "highly likely" the 2010 British Grand Prix would return to Silverstone. On 24 October 2009, BBC News reported that Donington had failed to raise the £135 million needed to stage a British Grand Prix, that Donington's bid 'looks over' and that Bernie Ecclestone had offered the race to Silverstone, but that the terms appeared to be the same as those that the Circuit rejected the first time around. On 7 December 2009, Silverstone was awarded the rights to host the British Grand Prix for the next 17 years . Part of the deal was for a new pit lane to be built. The British Grand Prix started to use the Arena circuit configuration since 2010, thus increasing the track's length by 759 metres. Ahead of the Grand Prix, a new pit complex was completed, making the straight between Club and Abbey corners the new pit straight. The British Racing Drivers' Club (BRDC) agreed to a 999 year lease of the Silverstone business park and development land around the outside of the Formula One circuit with property developer MEPC. MEPC has paid 32 million pounds for a long-term  lease. This payment has allowed the BRDC to pay off its long and short-term loans from Lloyds Banking Group and Northamptonshire County Council 2010 redevelopment. To make room on Donington Park's calendar for the switch of the Formula One and MotoGP British Grands Prix, it was announced in early 2009 that in return, Silverstone would get the option to host MotoGP in 2010 onwards. Both the FIM and Silverstone acknowledged a need for the circuit to be remodelled in order to become more suitable for motorcycle racing, with particular concerns raised by riders over the proximity of the  bridge at Bridge corner. A £5 million renovation plan was put forward in February 2009. The most notable change of the remodelling is the addition of a new "Arena" section that sees racers turn right at the old Abbey Chicane and head towards the new Arena section in what was then the infield, turning left onto the National Circuit straight and then rejoining the original Grand Prix circuit at Brooklands. The new 'Arena' consists of three new grandstands. Silverstone later claimed that the changes would make the circuit the fastest track on the MotoGP calendar. This additional section was  also used from the 2010 Formula 1 British Grand Prix. From the 2011 Formula 1 British Grand Prix onwards, the start/finish straight and pit building was moved from between Woodcote and Copse, to between Club and Abbey. The straight was renamed the Hamilton Straight on 12 December 2020, after Lewis Hamilton on the achievement of his seventh world title. Silverstone hosted the British round of the 2010 Superbike World Championship season, taking over from Donington Park after the circuit was deemed "un-raceable" due to the postponed construction that had commenced in 2009. The bridge section was turned into  a Wall of fame. In September 2013, Silverstone University Technical College, a school specialising in motorsports engineering, event management and hospitality, opened at the circuit. Spectator traffic management. Historically Silverstone has suffered traffic congestion 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. On F1 race day in 1999 there were  some 4200 helicopter journeys made to Silverstone Heliport, which was the busiest airport in the UK on that day. Current circuit configurations. Like many racing circuits around the world, Silverstone Circuit has a number of different layouts which offer differing lengths and complexity.
