Posted by 777fly: Yes, the initial wanderings are hard to explain but if one pilot (under stress) loaded a handful of waypoints, some correct (AGARI), some with errors, and then the crew were overcome before they could be crossed checked the aircraft could fly to some strange places. It only takes one wrong keystroke to produce hundred mile errors.
It's probably worth pointing out again that, at a press conference fairly early on, one of the Malaysian officials (their CAA CEO, I think) steadfastly and explicitly refused to confirm that the aircraft flew to the various waypoints on the zigzag track that has become so much a "given" in these discussions. He would only confirm that it flew back over the peninsula.
And today we learn that reanalysis of primary radar data has resulted in a re-evaluation of the aircraft's speed. Since one thing you can be positive about in respect of a radar return is it's timing, that very possibly means there has been a re-interpretation of one or more of the positions attributed to MH370.
Taking these things together, it wouldn't be the greatest surprise in the world to me if we learn at some point that MH370 didn't actually fly the wandering zigzag path that is so persuasive of criminal intent to many people.
