Oscar Pistorius, a double-amputee who runs on carbon-fiber blades, ran a 45.44 in his heat of the men's 400m. It was good enough for second place in the heat and to qualify him for Sunday's semifinals. Unfortunately, Pistorius did not advance to the finals. But it's still a remarkable story.
Pistorius, who was born without fibulas and had his legs amputated below the knee before he was a year old, has had to undergo extensive testing in his home country to prove his carbon blades aren't giving him an unfair advantage over runners with regular legs. Once it was shown that that was not the case, he was put on the South African national team.
