I have seen a documentary about people jumping off the Golden Gate Bridge and it was pretty strange. They have actual footage of people jumping captured by tourists just visiting. Scary. They have interviews with family and friends of those who have jumped and they also have an interview with a guy who survived the jump, although it messed himself up. He decided right after he jumped that he wanted to live and went in feet first.
They say it takes a long time to reach the water and it generally kills you right off when you hit. It was disturbing to say the least. You actually see people jump, several, in fact. They hang around on the bridge for a while and then sooner or later, unless someone can talk them out of it, they take the dive. One guy went off backwards in a swan dive.
