ran wide which allowed Nigel Mansell to move up to second position, but rejoining in third. Mansell then proceeded to quickly close the gap to Ayrton Senna in first place. But by lap 5 the incidents began to occur which would affect Mansell's ability to pass Senna. This was because so many yellow flags were being displayed by the marshals around the extremely wet circuit. On lap six Mansell moved alongside Senna on the Brabham Straight but quickly saw a wave from a marshal, who was leaning out from the barriers, to warn of wreckage ahead. Nicola Larini's Modena-Lamborghini had crashed on the straight and was lying across the track. Mansell had to abandon his line and rejoin the racing line behind Senna, who had also had to avoid Jean Alesi's stricken Ferrari, which had also crashed yards after Larini on the other side of the road, as did Schumacher's Benetton who also spun off on the side of the road. Pierluigi Martini's Minardi car aquaplaned on the Brabham Straight on lap 10, which sent his car straight into the right hand wall and rebounded to the other side of the track before eventually stopping out of the drivers' way. This indicated that the rain was beginning to fall even harder, and more torrential than before. On lap 14, Mauricio Gugelmin's Leyton House was involved in a heavy crash trying to pass the Tyrrell of Stefano Modena going through turn 15. He lost control in the right hand turn and hit the inside wall of the pit lane entrance at the turn 16 hairpin with such speed, he became airborne. Two track marshals suffered minor injuries from flying debris. Riccardo Patrese was struggling with his car because a front wing, from another car, got stuck towards the front of his undertray. This was spotted by James Hunt in the BBC race commentary, although Murray Walker had suggested earlier that it was the undertray that was loose. Mansell then, as a result of the increasing downpour, spun off on the start of lap 16 on the Wakefield Road straight, before turn 3, having "instantly gone out of control" according to Mansell himself. The torrential downpour also made Michele Alboreto spin out of the race on lap 15 as well as Modena, although he continued. Nelson Piquet also spun at the high-speed Stag turn but was able to recover and he continued
