3. Someone WILL die during the weekend. This is normal. They usually clear it up in about 40 minutes. When I was last there it was one of the ring marshals. Quite sobering.
While track management does not publish any official figures, several regular visitors to the track have used police reports to estimate the number of fatalities at somewhere between 3 and 12 in a full year.
From the wiki page.
I've been 5 times, and there's always been a fatality, worse was 5 in a weekend. It only gets recorded as a fatality if the death occurs at the track, doesn't count if its in the helo, or hospital.
