Double amputee reaches world 400 semifinals

The double-amputee sprinter known as the “Blade Runner” is steadily stealing Usain Bolt’s stage at the world championships.

Bounding along on his carbon-fiber blades, Oscar Pistorius is proving he indeed belongs on the same track at major meets as able-bodied athletes.

On Sunday, in his opening heat of the 400 meters, the South African finished third in 45.39 seconds to advance to the following day’s semifinals.
