Silverstone Circuit
Following the deaths of Ayrton Senna and Roland Ratzenberger at the  San Marino Grand Prix, many Grand Prix circuits were modified in order to reduce speed and increase driver safety. The entry from Hangar Straight into Stowe Corner was modified in 1995 so as to make its entry less dangerous and less challenging. The high speed Abbey kink was changed to a chicane in just 19 days before the  Grand Prix.
