>While Mr. Kim was watching, the ship lost balance when its stern slid down the launch slipway while its bow section failed to leave the ramp, it said. The accident tore holes in the ship’s hull, it added.

I can't imagine in a country like North Korea that the punishment will be light ... or even pick anyone truly responsible.
