with Patrese and Boutsen. This would prove to be Alessandro Nannini's only victory in a Formula One career that was cut short by a helicopter crash almost exactly a year later, which severed his right forearm. Senna's disqualification also meant that it was mathematically impossible for him to overhaul Prost's points total, and so the 1989 Drivers' Championship went to the Frenchman. As he had gained no competitive advantage by missing the chicane, Senna and McLaren attempted to appeal the disqualification ruling. McLaren boss Ron Dennis explained that it had nothing to do with stopping Prost (who was leaving McLaren for Ferrari) winning the championship, it was that the team strongly felt they had a win taken away from them by an incorrect ruling, and that resulted in a loss of prize money and bonus sponsorship money. At the FISA hearing in Paris later the same week, Senna's disqualification was not only upheld, but an additional US$100,000 fine and suspended six-month ban were imposed on the driver (FISA also labeled Senna as a "Dangerous driver"). Ever since the incident, there has been much debate as to whether Prost intentionally ran into Senna, whether Senna was overambitious in his overtaking move, or whether the collision was simply a racing incident between two embittered teammates. Race classification Notes – Ayrton Senna originally finished 1st, but was disqualified for rejoining the track illegally following his collision with Alain Prost.
