SYDNEY/PERTH - Chinese and Australian ships (click here) hunting for a missing Malaysia Airlines jetliner have picked up separate acoustic signals in different parts of a vast Indian Ocean search area and are trying to verify if one could be from the plane's black box recorders.
Australian search authorities said on Sunday a Chinese patrol vessel, the Haixun 01, had picked up a fleeting "ping" signal twice in recent days in waters west of Perth, near where investigators believe Malaysia Airlines Flight MH370 went down on March 8.
More planes and ships were being sent to assist in that area, but meanwhile, Australia's HMAS Ocean Shield had reported a separate "acoustic event" some 300 nautical miles away....
If journalists don't know the facts and physics they have to take the governments' word about what their findings. The families have been through enough, they don't have to go through speculation and guessing, do they?
The acoustics at depth are very different than in air.
