Bottom line, it appears to be speculation that the FMS inputs were altered.
They say it passed close to certain waypoints, but they would have been nailed with FMS input. This suggests heading inputs may have been made instead, or not.
Raw radar data may not accurately reflect path or altitude depending on type of radar and operator.
Thanks Jungle. That's what it had seemed to me, only circumstantial evidence with no definite proof of keying in new flight path. From what I can tell, they are assuming because certain waypoints were threaded, the assume it was programmed, but seems possible to fly those points via a hand held GPS or something. I don't understand why these guys on the news are so matter of fact about FMS reprogramming?
