If the Inmarsat Timing Rings are accurate, and if the Investigators' implication that MH370 flew by waypoints is true, and if the Investigators' insistence that MH370 could only have flown South is correct, then MH370's final location could be near S32 E92, assuming it flew due South after reaching waypoint KETIV.
I estimated the radii of the Inmarsat Timing Rings, then looked for any airplane that might have a correlation with the circle at 22:41 UTC.
SIA352 correlated with their 19:41, 21:41, and 22:41 UTC circles, flying North. I plotted SIA352's distances to the satellite, then mirror flipped and rotated those distances, to estimate where MH370 would be, heading South.
I made the further assumption that if MH370 flew South, as the Investigators insist, and if MH370 flew along waypoints, then I assumed it flew along these waypoints (to avoid land):
VAMPI MEKAR NILAM VIROT NIXUL KETIV S32E92
(I added S70E92 to extend the path down to the South Pole.)
That path correlated with the estimated 18:22 UTC radius, and the 21:41 and 22:41 UTC radii (in the Southern direction).
The 00:11 UTC circle (and 00:19 UTC circle, which isn't shown) intersect with the due South flight path near S32 E92.
Note: I am not saying this is in fact where MH370 is. I am presenting this as one possibility, based on what the Investigators have stated as facts in this case, and based on my estimates of the Inmarsat Timing Rings. Inmarsat has failed to provide the radii of their circles.
