in front of him with Prost's absence, was passed by the Williams' pair only a few corners after the start. Senna pulled away rapidly - he was almost 9 seconds in front after just the first lap, though he was also the only driver who had a clear track in front of him and was not affected by almost zero visibility. After a few laps in second place where he used better visibility and less wheelspin from his less powerful Ford V8 engine to stay ahead, Martini was passed in quick succession by both Williams' and Nannini and the trio immediately started to match Senna's now more steady rather than charging pace. They quickly left the Minardi with its inferior Pirelli wets well behind. The first retirement was Arnoux after he was pushed into a spin by Eddie Cheever and was beached on a high curb, ending his career on a low. Arnoux had actually been 2nd fastest in the wet pre-race warm-up behind Senna and had been confident of a good showing. Berger and Alliot then collided at the East Terrace bend, Berger taking out Alliot, while Derek Warwick spun into the turn 7 and 8 esses when his throttle stuck open (as seen by his onboard camera which showed Warwick lucky not to be hit by his own right front wheel after hitting the concrete wall). Then in the space of two laps, six cars retired. Both Dallaras spun out at the same place at Brewery Bend, though de Cesaris was able to continue before spinning again later in the lap and beaching himself on a curb, while Mansell, Nannini, Piquet and Cheever all had off track excursions. However, the major accident was Senna running into the back of Brundle while lapping him and Piquet. The crash was recorded by a rear view camera mounted on the back of Brundle's Brabham, television commentator Murray Walker describing Senna's McLaren charging into Brundle as "bearing down on him like Jaws". Senna, who earlier had multiple spins on one lap before the pits hairpin (losing only 4 seconds in the process), was out with major front suspension damage after returning to the pits with his left front wheel missing, as was Brundle, and the Williams' of Boutsen and Patrese were one-two with Nannini still in third despite his off track excursion. Ivan Capelli also retired his March. Five laps later, Mansell
