The Formula One World Championship started in 1950, and the first race in that Championship was the British Grand Prix at Silverstone in May 1950. The Coys International Historic Festival meeting at Silverstone in July 2000 celebrated 50 years of the World Championship with a representative display of cars from each of those five decades and several of them took to the track during the weekend on demonstration runs. Here's one of the cars that took part:
It's a 1991 Jordan 191, the first Jordan Formula One car, and it was driven on the demonstration run by John Watson. John Watson had never driven for the Jordan team but he was the first driver ever to test drive a Jordan Formula One car, in 1990.
Here's John Watson in the pit lane at the start of his run.
