I don't think anybody can disable communications from inside the plane (but then, that's a guess, if anybody knows better, please tell so).
It would be compatible with some group kidnapping the plane, and changing the route to go over the ocean. But the plane would have already appeared somewhere, so I don't think that's likely.
Also, if it was a bomb, it would need to be quite a big one, to completely destroy the plane. Also unlikely.
