Anyway what I find almost too good to be true is that looking at http://www.jacc.gov.au/media/release...l/mr_014-2.jpg all 4 ping detections are almost right on the "satellite handshake calculation" which I presume refers to the last partial ping. Surely this is either extremely lucky (no way the arc calculated thanks to doppler analysis can be so precise) or if this is indeed the final resting place of MH370 the location must be based on a more accurate data source that they are not willing to disclose...
