If you look at the ping rings from the inmarsat data, you would think the pattern is fairly symmetrical, a curve, MH370 flew out on a south west track across western Sumatra, and then seems to have turned back to mirror the first half of the flight.

Or maybe she was slowly losing altitude and slowing down? I doubt it was a nose dive or high velocity impact. If MH370 reached the roaring 40's her very design would I think make it hard to do a nose dive with such strong winds under her wings, especially if they were tail winds, or someone actually turned her to go with the wind. But I am not a pilot, and these ATSB expert keep telling us B777's fall like a rock or suddenly spiral down with the same impact.
