Perth: Search ships today failed to detect any more underwater pulses after signals possibly from the missing Malaysian jet were recorded over the weekend, even as investigators were racing against time to locate the black box of the ill-fated aircraft before its beacons fall silent.
“There have been no further contacts with any transmission and we need to continue (searching) for several days right up to the point at which there's absolutely no doubt that the batteries will have expired,” Air Chief Marshal (retd) Angus Houston, the head of the Joint Agency Coordination Centre (JACC) which is leading the search, said.
If, till then, the US Navy listening equipment being towed behind Australia's Ocean Shield fails to pick up any signals, an unmanned sub on board the ship will be deployed to scour the southern Indian Ocean seabed.
Investigators are hoping that the signals recorded by Ocean Shield could be locater beacons from the Flight MH370 data recorders, but they are not sure yet.
