Jeez, I didn't expect that. Presumably a volunteer.
I can only begin to imagine what those divers have been going through...horrific.
I honestly hope if it doesn't exist already this saga will prompt some ingenious individual to develop some kind of sonar repeater (echolocation?) / visualization system to aid searching in low visibility underwater environments. In 2014 I have a hard time grasping there isn't some better means available than feeling around in the dark with their hands. |

Unfortunately real life isn't as advanced as the movies. And not everyone has the cash to spend on ideal-semi-fantasy CSI style equipment. Also, most fancy technological things are developed for normal, on surface conditions. I think underwater inside a boat would be difficult, since dead bodies would be the same temperature as the water around it.
Best surfacing the boat now, but I guess politics and PR are preventing them doing it yet. |

| I have a hard time believing someone in the AP wrote that article; it is written as though a drunken 6 year old put it together. |

In this case we're not not talking Star Trek though. Sonar and ultrasounds are a technology we're quite familiar with.
3-D ultrasounds have apparently been a thing for at least 3 years.
And a few quick searches yielded "Forward-looking Sonar Mosaicing", which is basically exactly what I was thinking of.

I figure if anyone was going to have it, the US Navy would (they were peripherally involved, and the US military are exactly the type to spend on ideal-semi-fantasy CSI style equipment), but it looks like it's still pretty cutting edge. Perhaps 5 years down the road it would have been a different story.
Anyway, very sad to hear about the diver. The ferry claimed another life even after it's been on the bottom for almost 2 weeks. |

I agree. I have a great deal of respect for them. We're sitting at our cozy jobs, drinking at the pub, enjoying the beautiful spring weather...and they are in hell. Just imagine the psychological drain this must be taking on them as human beings. Worst job on the planet. And some of them volunteers to boot. They deserve a collective thank you from all Koreans, and an official acknowledgement of some sort. A medal, perhaps. The contrast between their heroic efforts and the moral delinquincy of the captain and crew couldn't be starker.
Hopefully it will all be over soon. |
