Underwater sounds detected by a ship searching the southern Indian Ocean for the missing Malaysia Airlines jet are consistent with the pings from aircraft black boxes, an Australian official said Monday, dubbing it “a most promising lead” in the month-long hunt for the vanished plane.

Angus Houston, the head of a joint agency coordinating the search, warned that it could take days to confirm whether the signals picked up by the Australian navy ship Ocean Shield are indeed from the black boxes that belonged to Flight 370, but called the discovery very encouraging.

“Clearly this is a most promising lead, and probably in the search so far, it’s probably the best information that we have had,” Houston said at a news conference. “We’ve got a visual indication on a screen and we’ve also got an audible signal — and the audible signal sounds to me just like an emergency locator beacon.”

After a monthlong search for answers filled with dead ends, Monday’s news brought fresh hope given that the two black boxes, which contain flight data and cockpit voice recordings, are the key to unraveling exactly what happened to Flight 370 and why.

Malaysian Defense Minister Hishammudin Hussein told reporters that in light of the new information, “We are cautiously hopeful that there will be a positive development in the next few days, if not hours.”

There was little time left to locate the devices, which have beacons that emit “pings” so they can be more easily found. The beacons’ batteries last only about a month — and Tuesday marks exactly one month since the plane disappeared during a flight from Kuala Lumpur, Malaysia, to Beijing with 239 people on board.

The Australian navy’s Ocean Shield, which is carrying high-tech sound detectors from the U.S. Navy, picked up two separate signals late Saturday night and early Sunday morning within a remote patch of the Indian Ocean far off the west Australian coast that search crews have been crisscrossing for weeks. The first signal lasted two hours and 20 minutes before it was lost. The ship then turned around and picked up a signal again — this time recording two distinct “pinger returns” that lasted 13 minutes, Houston said.

“Significantly, this would be consistent with transmissions from both the flight data recorder and the cockpit voice recorder,” Houston said.

Still, Houston cautioned that it was too early to say continued…
