something is very wrong
We can go around in circles for another 48.hours but this aircraft can not possibly have disappeared. This is relatively busy airspace thouroughly covered by Mil and Civ radar. If the 777 simply fell out of the sky some authority either knows where it happened or if she went off course before the event. Either way we need to simplify and stop speculating. Stop discussing what may have happened and start looking at where the 777 could now be nearly 48.hours into the incident.
