I checked some news article related to this, and Chinese have had problem with missile launch mechanism. They use a cold launch(rocket fired up after being ejected from the tube(even out of water?).) They could not get launch angle right in the past. So missile was ejected but may not go in the intended direction.

This put additional uncertainty for the missile's behavior.

And your source, don't tell me its also from Liberity time or Epoch time. I tell you something: the first stage of lanuch pop-up were shot through compressed air if you don't know, and this article openly claimed its failure were due to the failure of power-up stage of the rocket engine, so the first stage to get out of the water is succeed. More funny fact is, for such compressed-air powered VLS system, If its first stage failed it wont get out of the tube of the submarine, hence can not sink the submarine, as simple as that. Ironically, if its the second stage (power phase of the engine) failed like the aritcle suggested, the only scenario it can come right down the submarine is that:The engine powered up succesufully but the direct-control system failed, like American failed Trident-SLBM launch: Btw, the most recent Chinese JL-2 test conducted in 2008, which is 1.5 years ago, so how about you admit the Liberty aritcle is a joke. But I guess you just want to believe whatever you want to believe, which means, self-delusion.
