It has been quite a while since they have got ten any continuinn that it is still alive. >> the next thing to do is clearly to send down that auv that under water robot. see if you can locate something that would correspond those pings that were detected. >> thank you so much. still to come in the newsroom. lessons from the titanic. and ask why he believes the technology in the search for this missing plane may not be enough to get the job done. what can i do on a $7 a month android plan from tr...

Searches for things that dont belong beneath the sea. what is side scan sonar? >> well, side scan sonar is an acoustic technology that is based on reflections of sound rather than reflections of light. >> reporter: the autonomous underwater vehicle, an auv, is gathering information to create a map of the sea floor. this time, its the bottom of a massachusetts reservoir. but it could be the depths of the indian ocean. >> the side scan consists of an electronics package which is inside the vehicle...

Come close at least, rob, its still going to take months, maybe years to actually find the physical boxes, right? >> thats right. once we move to side scan sewn nor mode -- its detected by autonomous under water vehicle or a sled towed behind a ship. with an auv you might be searching 30 square miles a day, with a towed sled, maybe 120 miles per day. its a slow and painstaking business. once we find the debris field, then and only then can we operate the remote operated vehicles to go down with ...

Equipment now, most of the time we are using auv, on the air france flight we were using auv because the topography was better for towing sonar. but auv is a carrier, also, the so sonar, the same kind of equipment. that is the only way to see something under water because you dont care about the light, if it is dark or not with the sonar. you dont need any light. and you have the swab, which could be pretty big, much bigger than the towing sonar, the auv, more power, the battery cannot give the ...

Having said that, they still have to follow protocol in retrieving these boxes. win at this point, as david was saying, we still have a couple more days before we make the call to say lets now put in the auv and -- >> when that happens, by the way, and ultimately if the auv does the detective work we need it to do and is successful, then its all about robotics. because theres no diver in the world that can withstand that type of pressure. how effective is one of those robotic devices in finding ...

So we pull in that sonar file, went to that location and got a better high def image of that car. >> reporter: in the case of flight 370, an auv would face a number of obstacles that could stretch this entire process out for months or years. to get a real-time close-up image, this remotely operated vehicle, or rov uses the map to visit the location. >> all right. >> its pretty choppy out here today. so the visibility is quite reduced. >> reporter: in the depth of the indian ocean, you would prob...

Mh-370. i will provide a further update if and when further information -- >> it sounds like it is tony abbotts version of what angus houston has told us all along. >> the fifth ping doesnt exist. they are waiting for information on when to send down the auv. no major developments during the course of the friday search day. >> of course in deference to the family and tony angus houston doesnt want to give false hop or information. >> i need to correct myself, the thursday search day. >> got ya. ...

Thousand feet? >> theyre also to back up what theyve been hearing. you have a much weaker signal from these brack boxes and time running out. this is the last effort before you deploy an auv. if it were my teams id be trying to do this the next three or four days until you dont get a signal. >> such an incredible view to see this from the air to their complete deployment. a remarkable view to the work thats being done right now and hopefully this will lead to the answers everybody wants. where a...

They say they dont want the excess noise in the water. >> this is their best chance to find these pings. theyve located them in an area about 12 miles across. its not small enough yet. batteries might still have a little bit of juice left in there. so they really want to narrow it as much as they can before they commit the auv. its a much slower way of scanning the bottom. it takes about six days to do with the tow pinger locator can do in one day. if they go a couple days without hearing anythi...

Do you agree with that? >> it makes sense. they are going all in. they feel like this is their best chance to find these pings. they have located them here and there in an area of 12 miles across. its not small enough yet. the batteries might still have a little juice left in there. so they really want to narrow it as much as they can before they commit the auv. apparently, the auv is a much slower way of scanning the bottom. it takes about six days to do what the towed pinger locater can do in ...
