Oscar Pistorius falls short of Olympic qualifying time. He has three more chances, but Pistorius himself seems pessimistic: "I let myself down. I’ve got to be realistic. I’m chasing something that may be unattainable. It’s starting to look impossible."

Failure, here, would actually be a form of vindication. His opponents argued that allowing him into the Olympics was tantamount to permitting the use of jet packs. If his prothesis is such an advantage, how come he can't qualify? It's almost as though there might somehow be some disadvantages for a runner to have only one leg. Who would've thought?

Still, though, I hope he does manage to qualify. I understand that, even should he not qualify, he might compete in a relay event; I'm not sure if his awkward starts are more or less of a disadvantage in a relay setting, but I would assume he's not particularly well-suited to the format. But in any case, good luck, Oscar.
