Search teams hunting for the missing Malaysia Airlines plane have heard the signals again that could be consistent with those emitted by aircraft "black box", even as investigators were racing against time to locate the flight data recorders before its beacons fall silent.
The robotic mini-submarine deployed to search for the crashed MH370's debris on Thursday resumed the hunt after eight days of suspended operations ahead of its final week of scouring the Indian Ocean seabed, which will now be mapped to locate the final resting place of the jet.
The searchers hunting for the missing Malaysian jet are "very confident" that a series of underwater signals detected in a remote part of the Indian Ocean were from the aircraft's black box, the Australian prime minister said on Friday.
A robotic submarine deployed to locate the missing Malaysian plane's black boxes on the floor of the Indian Ocean on Tuesday aborted its first search as it encountered water deeper than its operating limits of 4.5 km.
The hunt for the missing Malaysian jet was on Thursday narrowed down drastically to a targeted patch in the Indian Ocean after fresh underwater signals possibly from the plane's black box were picked up this week.
Multi-nation search teams hunting for the missing Malaysian plane said they will stop listening for pings coming from the floor of the Indian Ocean and now deploy an unmanned submarine to track down the jet's black box.
An Australian aircraft searching for the crashed Malaysian plane on Thursday detected a new possible underwater signal in the remote Indian Ocean consistent with a plane's black box, fuelling hopes of a breakthrough in the arduous month-long hunt.
The arduous hunt for the Malaysia Airlines Flight MH370 on Friday entered a new phase with two hi-tech ships scouring a large area in the Indian Ocean for the black box of the jet before pings from it fall silent.
Search ships on Tuesday 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.
A pinger locator has detected signals consistent with those emitted by aircraft black boxes, raising hopes of finding the missing Malaysia Airlines plane a month after it mysteriously disappeared en route to China.
A number of "encouraging leads" of electronic pulse detected in the southern Indian Ocean on Sunday prompted multinational search teams to rush their hi-tech ships to the area to determine if these signals came from the black box of the crashed Malaysian plane.
The search for flight MH370 is yet to target a "hotspot" most likely to be the crash site in the Indian Ocean as priority was given to investigate "pings" that has led to a dead end, a United Kingdom satellite firm claimed on Tuesday.
A mini-submarine deployed to locate the missing Malaysian plane's wreckage on the floor of the Indian Ocean has completed a full 16-hour mission mission at its third attempt, authorities said.
The search for the crashed Malaysian jet continued on Sunday with 10 aircraft and eight ships tasked to scour the Indian Ocean, after early sightings in the new search zone drew a blank.
A mini-submarine deployed to find the crashed Malaysian jet has touched record depths in the Indian Ocean beyond its operating limits and embarked on a fifth mission on Friday, with still no sign of the plane's wreckage.
Multinational search teams were racing against time to locate the black box of the crashed airliner, as Malaysia revised the account of the critical final communication received from the jet.
Malaysian Prime Minister Najib Razak has admitted that Malaysia 'did not get everything right' in the first few days of Flight MH370's disappearance and called for implementing real-time tracking of airliners, as the search for the crashed jet was hampered by technical troubles on Wednesday.
Once searchers hunting for the crashed Malaysian jet decide to shift from listening for the acoustic signals from the black boxes from the floor of the Indian Ocean to poring over its treacherous terrain, they will have to draw from a whole new set of tools, experts say.
Australian Prime Minister Tony Abbott on Monday said it was now "highly unlikely" that any debris of the missing Malaysia Airlines plane will be found on the ocean surface, as he announced a more intensive underwater search
