Can you name the athletes by the picture?

I went to a Six Flags. Theres this new ride there; I had to wait in line for, like, four hours to get on this thing. Finally got on it, it was fine enough. But then I see a couple of weeks later in the news, this girl goes on the exact same ride and, in some freak accident, her legs got lopped off at the knees. I was like, What a terrible thing to happen to all of those people waiting in line.
