>> were asking them today. i imagine the families are saying throw as much resources as you can as possible. thank you so much. coming up we will take you live on a ship to see the challenges that investigators are facing. how the underwater landscape could mean that sonar technology that theyre using is wrong. starts with back pain... s ly ...and a choice. take 4 advil in a day which is 2 aleve... ...for all day relief. "start your engines"

Shouting. this was delayed. these fed up families, you see them here? they stormed out of this briefing. what are the challenges here? earlier the head said the sonar device will help move the searchers step further but he stopped short of pinning all hopes on the suv. >> i would caution you that the deployment will result in the detection of aircraft wreckage. however, this is the best lead we have and it must be pursued vigorously. >> she is back on a boat for this live demonstration of the so...

Its job, not to listen for pings but to map the ocean floor and look for debris. to do that, it can use two different payloads, which have to be swapped out. >> this particular payload section is the acoustic section. >> reporter: first the bluefin uses side scan sonar and a multibeam echo sounders that bounce sound waves off the ocean floor that arent natural. if picked up, the bluefin can be brought to the surface. the sonar technology is taken out and high-tech cameras are put in. >> its a hi...

Autonomous underwater vehicle. for the people who run it its -- >> basically a smart torpedo. >> reporter: and right now it may be the best remaining hope for finding wreckage from flight 370. we were given exclusive access behind the scenes at phoenix international, the company which runs the bluefin, to see just how it works. while it may launch from the side of a search ship, the bluefin is actually operated by remote control with help from a satellite. its job, not to listen for pings but to...

Control with help from a satellite. its job, not to listen for pings but to map the ocean floor and look for debris. to do that, it can use two different payloads which have to be swapped out. >> this particular payload section is the acoustic section. >> reporter: first, the bluefin uses side scan sonar and an echo sounder, it detects sound waves off the ocean floor that are not natural. if those are picked up, the bluefin can be brought to the surface. the sonar technology gets taken out and h...

Entirely gets into it like a very soft mattress almost. you kind of fall into it and go away. >> you have experienced the -- many depths, and what do you see? are you seeing what he is seeing? the silt, do you think it will be covered? >> no, i dont think so. because there are currents, you cannot avoid the visibility, that happened very often on the titanic, some days we dont have good visibility but some days we have a good one. it it could be -- that thing can change very fast. >> and speakin...

Seas, not very many white caps, which means its relatively easy to see debris that may be floating on the water. so you know, when you have more rough surf, the problem is, is its very difficult visually to get a good look at what may or may not be there. and the weather also affects the underwater search as well, because when you have clear conditions like this, the pinger locator thats being towed behind the australian ship, the "ocean shield," it can listen for longer. when you have rough cur...

A third party or the aircraft could have been commandeered by a third party, someone who would have the technical knowledge and skills necessary to operate the aircraft themselves without the crew. so any of those scenarios is plausible at this point. >> cary walsh, if this plane is in the southern indian ocean, the topography underwater, how much does that play into the difficulty of retrieving the ever-so-important black boxes? >> well, its going to play a lot into the difficulty. the area the...

Plans to move in any assets. that could change but as of everything we know right now we do not have plans to move in additional assets. >> tom costello who covers aviation. i want to give tom a chance to follow up on any of these loose en since youre taking the time to talk to us. >> as it relates to the equipment youre able to deploy in the indian ocean, are you dropping any sonar ability so that you can listen for pings from the black boxes and operately on the p-3 orion, can you talk about t...
