Dickie Stanford, Test Team Manager, Williams F1:
"Fortunately, it stayed dry all day today which allowed us to clock up the mileage with Nico while continuing our '09 development and set-up programme. The FW30B modified chassis covered 540 kilometres without encountering any problems and Nico will finish testing the scheduled items tomorrow on the final day of this week's test."
