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.

The following year, the new 3-litre Formula One was heralded as the ""Return of Power"", however the first Grand Prix under these regulations was held at Brands Hatch. It was not until 1967 that the big-engined cars came to Northamptonshire. The result remained unchanged, with Clark winning in the Lotus-Cosworth 49 at a race average speed of 117.6 mph. Second was Kiwi Denny Hulme aboard the Brabham-Repco, from the Ferrari 312 of his fellow countrymen Chris Amon.
