And anyone who looks at these very precise changes of headings at recognised way points can only come to the one conclusion that the aircraft was not critically damaged and was under the command of a professionally trained pilot.
What very precise changes?
If the ACARS 'pings' information is correct, then this route was constructed from between 5 and 10 triangulated positions at 30 min intervals. Just because someone has drawn a 'line of best fit' using known waypoints then superimposed it on a map of the area, that does not make it a verified route.
It is just a guestimate of where it may have gone.
