(Melbourne Herald-Sun) Underwater scientists have labelled the search for MH370 a "debacle" and say Prime Minister Tony Abbott was playing politics when he prematurely announced the black box pingers had been found.
The acoustic experts, who do not wish to be identified, said the four crucial signals detected by a US pinger locator were almost certainly not from the missing Malaysian Airlines plane's black boxes, but from another man-made source.
They insisted that the signals were in the wrong frequency and detected too far apart to be from the boxes.

"As soon as I saw the frequency and the distance between the pings I knew it couldn't be the aircraft pinger," one scientist told News Corp Australia.
That conclusion is supported by the lack of success from a detailed search of the area conducted by the US deep sea drone 'Bluefin 21'.
