The absolutely insane thing about it is not even the accident itself (most airlines have had accidents) but the way it is handled in their equivalent of FAA and the government. From how they delayed issuing the visas for Boeing and other representatives to how they STILL have not released a report.

great example of why I would avoid any PRC airline if I can help it.

(Presumably one reason they don't want to release the report is because it would lead many others to do the same and they want to protect their airline profits, but of course it ensures that the problem will not be fixed the longer they delay it)
