Algol I quite agree....therefore with that 'unlawful interference' theory it would have to be months in the planning, because the events after position IGARI what ever that maybe would unlikely be spontaneous. A plan was excecuted or attempted to be executed for what ever agenda. Also that would start pointing fingers within the flight deck, as when the aircraft reaches position IGARI, it could only be known from within the FMC/ND legs page and radio handover...no one down the back could determine when this position was reached i.e. The so called window of opportunity. Therefore clues could be found by further in depth investigation to the backgrounds of the Cpt and F/o.....something may have been missed that aids the investigation/search.
