Malaysia Airline flight 370 -- the unspoken fear

The disappearance of this flight appears planned leading me to consider this chilling possibility:
If this was carried out by a State or terrorist organization with State aid, the flight could have gone to any location with the radar data deliberately altered or ignored.  If so, I fear that the passengers would be considered minor inconvenient details, sacrificed to provide a civilian looking instrument of destruction. This plane then could be used (in a similar way as it was diverted) as a (possible nuclear) delivery system, as a substitute for another legitimate flight mid-flight with a surprise ending. Land it in Moscow or Washington or any other point of interest. No one would ever suspect. You wouldn't even have to alter its paint job, no one would see it until it was too late. Forget launching a missile, hijack an airliner.
Bang.
Sorry to give you reason to stare at the ceiling tonight . . .
