Trust The Technology

Paul Fearn saw this and brought it to my attention.

A rope snapped on a second-time amateur bungee jumper. He ended up in a creek, but because he was at the very end of the 400-ft line when the snap occurred, he wasn't much hurt and he is eager to go again.

Now, was it because he and his crew weren't professionals that they didn't spot the stressed spot on the cord, or was it just bad luck?
