1950 British Grand Prix
The 1950 British Grand Prix, formally known as The Royal Automobile Club Grand Prix d'Europe Incorporating The British Grand Prix, was a Formula One motor race held on 13 May 1950 at the Silverstone Circuit in Silverstone, England. It was the first World Championship Formula One race in the modern era, as well as the fifth British Grand Prix, and the third to be held at Silverstone after motor racing resumed after World War II. It was the first race of seven in the 1950 World Championship of Drivers.
Sebring International Raceway
The first 12 Hours of Sebring was held on March 15, 1952, shortly growing into a major international race. In 1959, the track hosted the U.S.' first Formula One race (the successor to historic European Grand Prix motor racing), held as that year's installment of the historic United States Grand Prix competition. However poor attendance and high costs relocated the next U.S. Grand Prix to Riverside International Raceway in southern California.
For much of Sebring's history, the track followed a layout. After a disastrous 1966 12 Hours with five fatalities, the track was widened and lengthened for 1967 with the removal of the Webster Turn between the hairpin and the top of the track and replacement with the faster Green Park Chicane. This was closer to the hairpin and allowed a flat-out run through a very fast corner to the top of the track and the runway. Another dangerous section was the Warehouse straight, where the organizers installed a chicane to move the track away from the warehouses and buildings after a crash where a Porsche went into one of the warehouses and into a crowd.
