Airliner missing between Malaysia and Cambodia/Vietnam, terrorism possible

Yes, who had motive,means and opportunity? Both the transponders were turned off. That took human action. Who had the means and opportunity to do that? IMO only the crew had those 2 . Now we need to find a motive and who had that motive.

It's worthy of some consideration, but given the lack of information indicating malicious intent, I don't see much point throwing around accusations about the crew. That may change, though.

The slow decompression theory that I've found the most compelling thus far has some flaws. Firstly, the aircraft turned quite a bit more sharply than you'd expect it would to leave the airway. Secondly, there's a visible and audible warning to the crew. There is a precedent where a crew ignored such a warning and subsequently crashed (see Helios Airways Flight 522 for example). People do strange things when they're suffering from hypoxia, though.

Edit: For what little it's worth, I am slowly beginning to agree that this looks like a deliberate act. I'm not quite there yet, but it's on my mind.
