shield has detected signals consistent with those of aircraft black boxes. the audible signal sounds to me just look an emergency locator beacon. reporter: the ocean shield picked up two distinct pinger alerts here. these signals detected 350 miles away from an area where a chinese ship picked untwo audio signals on saturday. britons hms echo has been moved there to investigate. they do not believe it s related to the ocean field find. i d say it s unlikely. but in deep water, funny thing happen with acoustic signals. reporter: officials dress they need to find wreckage before they can confirm any of these ping, related to the missing plane. we haven t found the aircraft yet. we need further confirmation.
broken off simply by pressure. so the weakness of the moment is no debris which is why the planes are going back over there to extend that area to see if they can find any debris. also, they will be bringing in the autonomous submersible that will go down once they have relocated that ping. richard quest, many thanks as usual. still to come in the newsroom, a high tk british ship is in the area where search crews heard the pings. renee marsh joins me with what they think the ships will do. we ll flush out what can hms echo do and will it help determine if those are truly the pingers from mh370. that s straight ahead.
location. it also falls along that arc. the satellite data shows the plane could have could have flown on and possibly gone into the indian ocean. there are a lot of questions about the technology the chinese were using. you saw the video of that handheld hydraphone being dunked into the water. some serious questions about whether that device could detect something so deep. we re talking about ocean nearly three miles deep in this particular area. we know the hms echo has been there doing surveillance but we haven t heard of anything significant that ship has found using more advanced technology. the real focus right now is on the ocean shield and its mission to try to get a lock on those signals once again. that australian ship does have a u.s. navy toed pinger locator, as they say, and that s a much more sophisticated device. will, we ll get back ton you. our panel of experts to get their take on what s being called the most promising lead so far it mike weiss is cnn aviation ana
it s just an update on the status of the search. you know, but, it feels like it could be a significant development. it feels like after the experience of the press conference yesterday when such a lot of detail was given, that it s going to be well worth, you know, kind of listening to. it s going to be given by angus houston, who is the retired air chief marshall here in australia that is heading up the multinational effort to look for that missing malaysian airliner. you know, remember, don, there are two main areas of focus at the moment. the one of them, perhaps the primary one, we don t know, where these chinese ship or this chinese ship detected a pulse from under the surface using their equipment and where the british vessel, the hms echo is now headed and has now arrived and has now started also to try and look for some kind of pulse with its high-tech equipment underneath the surface of the indian ocean. but there is another area as well, which i think we shouldn t
hms echo is in the area to check that out. two other sounds were picked up in other areas. there is a news conference going on. they re doing preliminary introductions with a we re going to hear is captain, we re going owe to hear chief coordinator air chief angus marshal houston, retired. this has promising news, mr. houston warned people being careful moving forward they want to make sure all facts are on the table. saying the strevength of the signals have not been linked to flit 370. let s hear what he has to say about the latest update. on the missing malaysian airlines flight ms 370. the electric pulse signals detected by the chinese ship and
