Amazingly, this woman survived quite a fall from the cables. She tells her story.

I witnessed a similar fall in 2007 where a man did not make it. Saw him slide by, and then got catapaulted below the subdome saddle. I heard he actually had a pulse when people reached him, but he succumbed to his injuries.
