We were there that day, the race was started even though it was obvious to all that there would be very heavy rain very soon. Sure enough, it came, drivers were all over the place (Raikkonen tried to turn into the pits but his car went straight on) and the race was red flagged. Winkelhock had pitted at the end of the warm up lap to change onto wet tyres, meaning that he had to start from the pit lane; being on wet tyres was an enormous advantage, such that when the race was red flagged he was in the lead. So he led from pole position at the restart, it was one of the quickest loss of places be a pole sitter ever.
This was the one and only F1 race that Winkelhock raced in, although he had taken part in a couple of Friday Free Practice sessions in 2006.
