The second of two ninety minute sessions will bring the first day of F1 action in Belgium to a close. Teams have plenty to do to catch up with each other after their holiday (which included two weeks of enforced shutdown), whilst the drivers are eager to brush the dust off their driving skills and get back in action. The weather forecasts suggest rain for Friday at Spa, which wouldn't be an unusual sight, but may play havoc with the programmes the engineers are hoping to complete.
