I am pretty sure a risk assessment of the whole grandstand/pit complex was carried out 3 or 4 years ago.The findings were so horrendous that it was quietly shelved.

One for instance was how do the control tower occupants escape if case of a fire.Getting the brigades long ladder up there in the middle of a race doesn't bear thinking about,and I think one or two occupants in particular would be virtually impossible to evacuate.

As previously stated in a famous song 'the love of money is the root of all evil'
