S.A's 'Blade Runner'

Oscar Pistorius, South Africa’s paralympic athlete, has had his hopes of competing in next month’s World Championships in Japan dampened, following an unfortunate incident at the British Grand Prix.

In wet conditions Pistorius, last of those who finished, was subsequently disqualified for running outside his lane. The 20-year-old South African runs on carbon fibre blades attached to both his legs below the knee and his artificial 'limbs' are currently the subject of an investigation by the International Association of Athletics Federations (IAAF). They have previously ruled that the blades are an unfair advantage but have said they will wait before making a final ruling.

I don't understand why the IAAF would think the blades give Pistorius an unfair advantage? Surely the blades can't be that advantageous if he still finds it difficult to remain in his own lane at times. Then can you imagine how challenging it must be to win a race on those things?

Below is an interview with Pistorius on the matter.
