Most defiantly too early to determine anything, the information just isn't there.
Yes, agreed. If you go to the FlightAware site that I linked, you will see extensive discussions, some of which I participated in....but keeping in mind that I tried only to deflect wild and ridiculous speculations.
Knowing what I know, there is less than 0.1% chance of mechanical failure. Other ideas occur to me:
Terrorism, i.e. a bomb
Suicide, i.e. Egypt Air 990
Or...an accidental "shoot-down".
(There may be more possibilities that haven't occurred to me)
One 'positive' aspect of this is the depth of the waters, where the airplane was lost. Not nearly as difficult as in the deep Atlantic Ocean, as was the case for Air France 447.
Stay tuned.
EDIT: A post from FlightAware which seems fairly pertinent:

And, I just realized that contrary to my earlier post, I have engaged in "speculation". So, I will attempt to focus on the (apparent) possible "conspiracy" about two suspicious passports. AND, as I "predicted" on the FlightAware site, a "conspiracy" always seems to crop up, with these major news events.....
