That fellow on the cruise ship has to be the luckiest man on Earth. I've seen people killed doing much shorter jumps, and (according to the story) this supposedly happened at pier, so if the impact didn't kill, it's likely the relatively shallow depth of the water should have when he hit bottom. Must have had cliff-diving experience.
@Cyber Liberty Had a similar occurrence within a mile of me a couple of years ago. Three local "youts" were crossing a body of water on a bridge that went up high enough for ships to sail under it,and got the bright idea to jump off the bridge. The first one did jump,and when he didn't come back up to the surface,the other two ran to get help. These rocket scientists didn't consider how deep the water was,or more correctly,how deep it WASN'T,and when he hit he sank in the mud up to his knees and couldn't get out. He drowned right there.
And come to find out,the guy that jumped thinking he was playing and would be ok wasn't the first one to try it.
You would think local boys would know better,but teens don't always think before they act. Don't ask me how I know this. It's too painful to discuss.
