But, if the news reports are accurate, a big if, the plane didn't just fly on in the direction it was pointed. According to the radar tracking it was navigated along at least two set navigation waypoints.
I Believe this is now the third time I have made this point in response to why this theory has problems. This is why I keep saying that any plausible theory can't ignore ignore inconvenient information.
If the plane was on autopilot it doesn't just fly straight, does it? It can fly on a predetermine flight path, no?
It can, but the rest of that flight path must also be programmed. The plane left ground with a flight path programmed for China from the filed flight plan.
We know a new turn was programmed into the FMS but not if more that that turn was programmed.
