reporter: ocean og rafrs say they should maintain their search for mh 370 in the area off perth, australia they ve been focussing on. it is possible this is the only thing they ll ever find or recognize from mh 370. that s just the way the ocean behaves with the difference in currents and winds and storms and whatnot, so this could well be the only piece that survived. reporter: experts point to another mysterious case the hmas sydney during world war ii. it went down off the coast of free mantle. there was no bodies nothing. search teams didn t discover that wreck until 2008. brian todd cnn, washington. and to the netherlands now. at least 20 people were injured
experts point to another mysterious case in that same region, the sinking of the australian worship, the hmas sydney it went down off the freemantle, australia, right off the right near super pers. now despite a massive search by the royal australian navy, there was no confirmed discovery from any of that vessels in the months and years after the disappearance, no bodies, nothing. search teams didn t find this wreck until 2008. asserts say a big ron for that is because the ocean currents are so inconsistent in that area. wow, brinen. i wonder if you ve got even more pieces that you find from mh370, do you necessarily get more answers? you really don t necessarily get more answers. they say if this is from mh370,
discovered the titanic or the hmas sydney, which is world war ii wreckage. we understand from our sources that this agreement could be reached within the week, and some authorities are talking about a search operation, planning for a search operation through july. poppy? when it comes to those more powerful submersibles, erin, we know they exist, but they could be anywhere in the world. and we also know it takes a significant amount of time to get them there to where you are. do we have any sense if any of those are on the way? reporter: not at the moment. that s something that australian authorities have not said, just something that we understand that they are considering. we hope to get more information on that in the coming days, but they are certainly considering deploying more underwater submersibles into this area, a potentially broader search area, poppy. again, 95% of that search area now complete with the 13th mission under way of the bluefin-21. we will come back t
signal detected. so, you d think they might find something, having searched around in that 6-mile radius, but no signs of mh-370 so far. some analysts suggesting, perhaps, they should search in the area of the other three pings that had been detected. perhaps they should search along that arc, the so-called half handshake between the inmarsat satellite and the plane, all things being discussed. malaysian proposing also, perhaps, introducing more powerful underwater submersibles to help in the search, perhaps along the lines of a submersible called the orion, which is capable of going about a mile deeper than the bluefin-21 and staying down weeks on end. the australian defense minister was quoted earlier in the week as saying they were considering more powerful underwater submersibles along the lines of those that discovered the titanic and the world war ii wreckage, the hmas sydney. we expect the agreement within
far. every lead, authorities say, they re taking seriously as important as either to rule in or rule out. it remains unclear at the moment if they re planning to rule this out any time soon. malaysian officials also said they may be bringing in more assets, their word, assets, to the search zone. what exactly are they considering? it s also something we re hearing from australian officials. david johnston, a defense minister, was quoted in the media today as saying they re considering more underwater submersibles that have more capability, capable of going into deeper waters. he said submersibles like the ones used in the hmas sydney wreckage find and also the submersibles used to find the titanic. this underwater area they re searching now, they ve managed to rule about 80% out. so australian and malaysian authorities now thinking very seriously about next steps,
