Oscar Pistorius' Olympic run came close to ending on a sour note. The South African who is the first amputee to compete in track and field at the Olympics didn't get a second chance to run. Though he was entered in the 4x400 relay, his teammate was injured before the baton was ever passed. However, track's international ruling body said the South African team was obstructed, and allowed it to move on to the final.
