At yesterday's 2008 Paralympics in Beijing, a huge pileup occurred in the final seconds of the women's 5000 meters, with six of eleven racers getting taken out in the last 500 m of the race.
Canada's Diane Roy, who set a Paralympic record with a time of 11:45:03, was awarded the gold. But after three of the nations competing protested, officials decided the race would be re-run.
