On 2 November 2008, Felipe Massa won his home Grand Prix and was on course to be Formula 1 world champion. Then Lewis Hamilton passed Timo Glock in the final corners at Interlagos.
As F1 returns to São Paulo this weekend, here is how that title decider played out.
Seven points and one simple sum
The Brazilian Grand Prix was the last of 18 races in 2008. Hamilton led for McLaren on 94 points, seven ahead of Ferrari's Massa on 87.
The sum was simple. Hamilton would be champion if he finished fifth or better. Massa could only take the title if Hamilton finished sixth or lower, and he would win any tie on countback because he had more race wins.
Massa did his part. He took pole position, his third in a row at Interlagos, with a lap of 1:12.368.
Rain at both ends of the race
Heavy rain fell just before the start and delayed it by ten minutes. Massa went on to win the race from pole.
Light rain returned on lap 63, with eight laps left. Almost every team called its drivers in for intermediate tyres, which are made for a damp track.
Toyota kept Timo Glock out on dry tyres. As the cars ahead pitted, he climbed from seventh to fourth, which pushed Hamilton down to fifth.
Two laps of chaos
On lap 69 the rain grew heavy. Hamilton ran wide and Toro Rosso's Sebastian Vettel slipped past him into fifth.
That dropped Hamilton to sixth, and as things stood Massa was champion.
Glock was struggling for grip on his dry tyres. In the final corners of the last lap, Vettel and then Hamilton went past him.
Hamilton finished fifth, and that was enough.
Champion by one point
Hamilton won the title with 98 points to Massa's 97. At 23 years and 300 days, he was then the youngest champion in the sport's history, a record that Vettel took in 2010.
Massa said afterwards that he had "almost done everything perfectly", and he congratulated Hamilton. Ferrari had some consolation: Massa's win and Kimi Räikkönen's third place sealed the constructors' title, with 172 points to McLaren's 151.
Massa never won another Grand Prix. His victory that day was the 11th and last of his career.
