The Belgian Grand Prix at Spa has been abandoned after heavy rain. Half points have been awarded, but which at which other races in Formula One history has this happened?
Half points awarded in Formula One for just sixth time
In the history of the F1 world championship, just six races have been stopped early with half points awarded.
Under current F1 rules, drivers must complete 75% of a scheduled race distance for full points to be dished out.
At Spa, this equates to 33 laps of the planned 44. However, heavy rain made this impossible.
After a three hour wait, two laps were completed for a classification to be taken.
Max Verstappen scored the Belgian Grand Prix win for Red Bull, receiving 12.5 points.
George Russell was allocated nine for second place, and Lewis Hamilton got 7.5 for third place.
Tragedy and history in first Formula One race with half points
The first race to be stopped and half points awarded was the 1975 Spanish Grand Prix.
A big accident on Lap 29 of 75 at the Montjuich Park circuit near Barcelona killed five spectators.
It was not restarted, with McLaren’s Jochen Mass taking his sole F1 grand prix win.
This race was also the only occasion in F1 history where a female driver scored (half) points.
Lella Lombardi was classified sixth. Under the scoring system in place, this was worth one point – which was halved.
The second race to award half points came later in the same 1975 season.
The 1975 Austrian Grand Prix became the first to be stopped because of heavy rain.
Italian Vittorio Brambilla was awarded the win after 29 of 54 laps were completed.
American driver Mark Donohue died after a practice incident.
The Penske driver went into some catch-fencing, and later collapsed into a coma and died from his injuries. A marshal also passed away.
Half points decides F1 world title
The third instance of half points in F1 history came in the 1984 Monaco Grand Prix.
Race leader Alain Prost was desperate for the race to be red flagged in a sodden event in the principality.
Ayrton Senna and Stefan Bellof were quickly closing in on the leading McLaren.
After 31 laps of a planned 76 on the Monegasque streets, organisers threw the red flags.
This would also decide the 1984 world championship.
Prost was only awarded 4.5 points for the win instead of a full nine.
In the final standings, he lost out to McLaren teammate Niki Lauda by 0.5 points.
That is the closest finish in the drivers’ standings of all time.
Australia’s unwanted record gone
The 1991 Australian Grand Prix previously held the record for the shortest F1 race of all time.
Just 24 minutes after the start, the race in Adelaide was red flagged due to heavy rain.
Brazilian driver Ayrton Senna took the win to round out a title winning season for McLaren.
The 2021 Belgian GP usurped this race as the shortest in the history of the world championship.
2009 the last abandoned race in F1
Remarkably, before the Belgian GP, F1 had gone over 12 years without abandoning a grand prix.
The last time this happened was the 2009 Malaysian Grand Prix in April 2009.
A monsoon swept across the Sepang circuit, leaving conditions undriveable after 31 of 56 laps.
Brawn GP’s Jenson Button took his second win of the season in two races.
He was joined by Nick Heidfeld and Timo Glock on the podium.
This was the race where Kimi Raikkonen famously went for an ice-cream during the delay.
