Just some general thoughts:
As we see, the conversation regarding fl370 has for the last two (+) days been largely consumed with discussion of the pilots and their possible involvement.
Malaysia has given very little new information, and keep reiterating that they are looking into the crew.
The major news channels have run with that and are also discussing the pilots.
IMO, this is all by design.
Designed to divert the public's attention, while in the meantime, they have IMO narrowed passengers to suspect ones, and all intelligence agencies busy trying to see who they are and who is behind this and what they did and how they did it. And most importantly, where the plane is and what they did with it.
I don't think they really suspect the pilots at all, I think they would have already done enough research on their movements in last few days and months, to either rule them out or know with great confidence that it was one of them.
JMO.
