My understanding is that the investigation team has the (distance/angle) data from all six(?) pings but has only publicly released the last one.
However, apparently CNN started reporting a few hours ago that the second last ping was from approximately the same angle as the last one. But they (I think mistakenly) thought that that meant the plane had stopped and apparently they have gone silent on this since then.
To repeat, all we know is that at 8:11am the plane was on (or crossing) one of the red arcs.
The public know nothing about where is was before that. The experts will know a bit more from the previous pings.
And not even the experts know where it was after 8:11am.
Except we can guess that something happened to the plane before about 9:11am.
