In an article titled "The mystery about the animation file showing warship 'Cheonan'" he wrote that the results of an analysis of the animation file on the sinking of the warship shown to foreigners by the Ministry of Defense led to the discovery of something rising between the bow and stern of the broken warship two minutes after the clash.

He held that the above-mentioned thing was not a thing floating as claimed by the ministry but a huge thing and the fact that it was moving against the flow of the sea water clearly suggested it had a powerful engine.

Conveying this fact, the newspaper said: It was such animation file that it could clearly confirm the following scenes: When this thing rose to the surface for a while, some of its huge black body was seen on the surface and, at the same time, both the bow and stern of the warship were seen terribly shaking.

It is only the submarine that has its mast, its huge part remaining under water and a powerful engine. There is an increasing possibility that the warship was sunk due to its clash with the submarine.
