is crucial in figuring out the fate of flight 370. that s because the cockpit recordings and flight data could provide the only explanation why the plane veered so far off course. as abc s david kerley explains, with each passing day, hope is fading. this u.s. navy listening device thousands of feet below the surface heard something like this. towed pinger locater heard it. it was for more than two hours. the ship, the ocean shield, it turned around and heard it again for another 13 minutes. two distinct pinger returns were audible. significantly, this would be consistent with transmissions from the flight data recorder and cockpit voice recorder. the ship is crisscrossing a nine square mile section of the south indian ocean listening again. searchers hope for a third hit and will send this robot down to the bottom using sonar it will map the ocean floor looking for
approximately 2 hours and 20 minutes. hmas ocean shield then lost contact while conducting a turn and attempting to reacquire the signal. the second detection on the return leg was held for approximately 13 minutes. on this occasion, two distinct pinger returns were audible. significantly, as stated by angus houston, this would be consistent with transmissions from both the flight data recorder and the cockpit voice recorder. separately, the chinese ship has also detected similar signals twice. in line with nations consistent stand on refining and corroborating evidence since day one of the operations, i would strongly urge all of the parties concerned to treat this information responsibly and to give time and space for the authorities to conduct further verification. malaysia also concurs with the
signal. the section detection on the return leg was held for approximately 13 minutes. on this occasion, two distinct pinger returns were audible. significantly, this would be with recorder and cockpit recorder. remain in the area and continues to remain in contact with the tow pinger electricitier. at this point he has not been able to reacquire the signals. this is the scary news, at any time the bears are batteries are expected to die. roger maynard is live in sydney. roger? well, hello, greta. this is obviously a major break through. the australian navy vessel picked up the pings in the last 4 hours. as one occasion it lasted
welcome back, planes approximate and planes and ships are continuing the search. a pinger locater has detected more audio signals in the indian ocean. those latest signals were picked up in the northern path of the search area. the australian ship, ocean shield, two distinct pinger returns were detected. the leader on of the search operation said it could take days to confirm if the signals are indeed from flight 370. so the search takes on a new direction and authorities are encouraged but very cautious. and searching for anything but 800 meters of water, it s a complex undertaking and now we are joined by david gallow, it s
consistent with those emitted from aircraft like boxes. two separate signal detections have occurred in the northern part of the search area. the first detection was held for approximately 2 hours and 20 minutes. the ship then lost contact before conducting a turn and attempting to reacquire the signal. the second detection on the return leg was held at approximately 13 minutes. on this occasion, two distinct pinger returns were audible. significantly this would be consistent for transmissions from both the flight data recorder, and the cockpit voice rd recorder, need to be honest with you, it could be days to establish where the detections can be confirmed as being from
