The scary thing here and I hope I'm not coming across as an alarmist, is that if this is so far a successful hijacking and the plane is hidden somewhere, then what's the next part of the plan?
Thus far the 'hijacker's' pretty much have the whole World watching. They have every-bodies attention. Is it possible that the passenger's may still be alive and they are planning on reloading them, putting them back in the air and may make some demands using the passenger's as a bargaining chip. I mean everyone's watching, it's a good way to hold something to ransom?
The only good thing about this scenario is that the passenger's may be alive somewhere and there's still a chance for them to be saved.
Or could they just be planning to use it as a weapon at a time that suits them? A 9/11 scenario perhaps? Passenger's not alive.
Presumably all Nation's are about to spend a fortune on Defence. If they can't find that plane all Countries in the vicinity are going to be watching/monitoring their skies with increased vigour....
They have managed to pull something off that none of us would have thought possible in this day and age.
I don't think that they have crashed into the ocean. There has been too much effective and efficient planning for it to simply end like that and I prefer not to think that anyway because I want the passenger's to be alive.....
Who knows really but I don't think it will be long until we find out!
