With no new pinger signals being picked up in the hunt for missing flight MH370, the search effort will go underwater. An unmanned submarine, named Bluefin 21 may be sent to look for signs of the Boeing 777.
Searchers are waiting for new ping signals before sending out the sub.
“This is an Herculean task,” explained Australian Defence Minister David Johnstone. “It’s a very wide area, the water is extremely deep. This is day 32. You can be assured that we are throwing everything at this difficult, complex task in these next at least several days.”
The search is reaching a critical stage, with the battery life of the black box recorders nearly at their limit.
Over the weekend two signals were picked up by ships, allowing the authorities to narrow the search area to a 600km corridor of water in the southern Indian Ocean.
The families of the 239 passengers aboard the Malaysian Airlines plane held a vigil in Kuala Lumpur on Monday, after one month of waiting for news, they hope the fate of their loved ones may soon be known.
