The fin just looks too straight even at that angle, and we have seen many J-10 pics before. There is something very wrong about the fin. Crash like that and there is no burn? That kind of crash would surely have ripped apart the fuel tanks. Another problem is that the plane's interior should have all sorts of yellow primer, not white. If you remember the KJ-200 crash, there were yellow all over the wreckage. In addition to all these, the section should have been hollow due to the air duct feeding the engine.
