This story does not appear to be going away anytime soon. This work pretty well rules out the idea that the craft flew into the Southern Indian Ocean. And of course it reopens the far too readily dismissed Bay of Bengal anomaly. As well, the sighting by the yacht in the Bay of Bengal of a low flying aircraft streaming smoke conforms to this scenario as well. However that makes the pings misleading and we are already going there.
That report also had the clear ring of authenticity as well. Other reports are second hand but further west. This also suggests that the plane failed to stay aloft all that long after whatever happened took place. All this conforms to a fire breaking out in the cargo hold, emergency measures taken by the pilots to deal with the problem before succumbing to the fumes and the plane itself succumbing to the fire fairly quickly thereafter..
Right now we have found a wreak that needs to be looked at. Excuses are unimaginable.
