I think that 777 is being chopped up piece by piece and being systematically destroyed.
All the ROP has to do is keep certain electronic signature devices on board and either place them in a cargo manifest on another plane to be remotely activated as that plane enters say Israeli airspace or cloned and sent with several planes say flying into or near NYC.
Officials get a sudden radio signature that incoming identifier signals say MH370 and in the confusion and fear send out fighters who start shooting at anything sending transmissions, from the cargo holds.
If I were ROP that may be one of my plans.
