Kamui Kobayashi set the best time in FP1 on a Spa Circuit which lived up to it's reputation by providing a deluge for the entirety of the session.
Maldonado and Kobayashi traded times with the Toro Rosso's of Vergne and Ricciardo the only four cars to do a time better than 2m13s.
A number of the drivers had scares at Eau Rouge due entirely to the changing conditions around the track - changing from heavy rain to even heavier rain at a number of places. Webbo put his foot down coming through Radillon to find himself up behind a slowing car and had to take to the escape road. the speed he was going, coupled with the lack of visibility, would have probably required avoidance tactics anyway.
Bottas was out in Senna's car and did reasonably well in what must be described as "difficult" conditions. for the few brave souls, outside the covered grandstands, who ventured out into the weather to watch their heroes - I feel for you and I applaud your dedication.
Towards the end of the session some of the guys came out for a couple of "hello" laps, but generally it seemed that the consensus in the garage was to keep snug and dry.
Massa's car stopped out on track after the chequered flag; given the weather out there he probably flooded the engine (chortle).
