@Passenger_389: Completely agree with every statement you made. Couldn't have said it better myself. The theories are getting more bizarre, and are becoming less factual. And it's a stretch to say there are many facts to begin with.
Anything is possible, within reason. A plane lost without debris, at least at this point in time, narrows things down only marginally: e.g. areas searched, mechanisms of crash.
Apologies for putting it bluntly, but this story is in its infancy and has yet to be told. It will be fascinating once discovered, but until then, everything is mere speculation. Being a pathologist (side job as pilot) it's akin to trying to postulate a cause of death and not even having a body to autopsy yet. We're still at the "missing person" stage. Once the correct areas are searched thoroughly, evidence will be uncovered. Undoubtedly it will. Until then? Not much to go on, in my humble opinion.
Of course the theories will continue to run wild...
