ship wreckage and rescue efforts

It's been a week now but it is still not known what caused the South Korean navy ship, the Cheonan, to break into two and sink, which might have taken 46 precious lives with it. Relatives of the missing sailors still believe their sons, fathers, or husbands are still trapped inside the ship, alive, but chance of that looks increasingly slim.

Right after the explosion, the other ship which was patrolling father south was ordered to move closer to the Northern Limit Line to guard the area, and soon detected an unidentified object moving fast northward on its radar. The ship fired artillery toward it for 5 minutes, suspecting that it might have been a North Korean submersible ship that attacked the Cheonan and ran away. But the military later said that the object was a flock of birds given the characteristics of the movement.

Defense minister Kim Tae-young a few days ago said the left-over mines dating back from the 1950-1953 Korean war might have caused the explosion, but people is skeptical about the possibility of more than 50-year-old mines still working properly.

The military is saying there was no unusual activities by North Korea detected on the night of the incident, but it can't possibly detect every single sinister movement, can it?

Having seen frantic, unorganized rescue operations and the lack of rescue facility by the South Korean Navy, I am really worried about their readiness for a possible war with North Korea.

Elite divers risk their lives without even proper equipment and there is lack of decompression chambers which are crucial for them to keep working for the dangerous operation. Strong current and poor visibility are also working against the rescue efforts. US Navy's divers who arrived at the scene a few days ago have not been able to go into the water because they are not allowed to do so according to their manual.

Sorry to say this but we should not push Korean navy divers to go as far as risking their own lives to save people down at the bottom of the sea, who is likely dead by now.
