caused the red flag to be shown when he heavily crashed his car at the entrance to the pit straight directly opposite the pits. Television broadcasts showed a driver's eye view of the accident, as the Arrows of Cheever and Derek Warwick were carrying forward-facing cameras for the weekend. Coming out of the final hairpin onto pit straight, Cheever ran wide over the curbing and hit the concrete wall that protected the grandstand from the cars, severely damaging the left front and rear of the car and leaving a large pool of oil on the racing surface as the car came to rest lying across the middle of the track. Cheever himself was unharmed; after he threw his steering wheel away in disgust he climbed from the car, ran across the track and jumped the wall into the pits. The four that failed to qualify were Jonathan Palmer in his Tyrrell, in what proved to be his last Grand Prix before becoming a pit lane reporter for the BBC in 1990, Luis Pérez-Sala in the Minardi, who was significantly slower than teammate Martini in his last Grand Prix, and the two Rials of Bertrand Gachot and Pierre-Henri Raphanel, who were two seconds slower than Sala. Despite a fourth for Christian Danner at the US Grand Prix, it was not enough to save the team for next season. Raphanel would also depart Formula 1 having only qualified for one race, while Gachot secured a drive for Coloni in 1990. Qualifying classification Race Pre-race Sunday was cool and overcast with rain being forecast for later in the day. After the morning warm-up session, the rain arrived just before the second Group A touring car support race of the weekend, and an extra 30-minute session (already organised for such an occasion) was arranged for the teams to set their cars up for what would be a wet race as the weather forecast had the rain staying around all day. During the extra session a lot of drivers aquaplaned off the circuit, some on their out lap, notably Prost and Berger. Senna spun his car a full 360° over the high curb on the outside of Brewery Bend, his car emerged pointing in the right direction and he continued undamaged down the Brabham Straight. Prost and Berger, along with Nelson Piquet, Thierry Boutsen, Riccardo Patrese and Alessandro Nannini discussed not racing over safety concerns
