The passenger of a plane flying over the Japanese Sea managed to film a huge object under water.
The passenger thought it was a submarine that was in the sea of Japan, but after the video analysis, it was demonstrated that the object was too big to be a submarine.

The size of this unidentified object is much larger than that of a carrier.
In the video, you can see quite clearly that the mysterious underwater object is moving underwater.
Watch the video for more details:
What is your opinion about this huge unidentified underwater object in the Sea of Japan?
