I am just pointing out that there are still plenty of reasons that can have the same pattern of the crash. Just look at past incidents. Unless proven otherwise, nothing can be excluded. This is the one and only way to enhance security for the benefit of everyone.

On there other hand, there seem to be people in this thread being fixed to one single cause. I honestly doubt if this is a wise approach ... Being in China does not necessarily mean that the pilots are less educated and professional. There are plenty of incidents in US history which are related to poor crew actions.
