>> yes. they would have to have a good idea of the blueprint of the vessel. it can be disconcerted especially in something where it is flipped. stairs that would normally be on the bottom will be over your head. >> if anyone is found, the mini rov is equipped with a grabber, strong enough to pull a human being out of a sunken ship on its own. >> you are actually with the rov. can you show us more about it? the technology is incredible. ive never seen this. >> it is fascinating. this is one we we...

Have cleared what was one potential obstacle. then you get ready to move on to the next one. here is the other problem that comes with the moving on to the next one. jeff, what im going to ask you to do is lift is on. jeff, the pilot, hes going to announce like top cyber lifting off. then you are going to see something that is going to be a problem. >> it will happen now. we engage the thrusters, the bottom gets a tremendous blast of water from the vertical thrusters and stirs up the bottom. eve...

>> its slow and tedious, as you say. tedious is an excellent word. you have to take every step so very slow. once you have completed one step and one move, of course the movement of the vertical thrusters particularly stirs up the bottom. and youre liable to have a big dust cloud about a secure you. you have to wait for that to calm down before you can move again. so its step by step by step. >> and it takes a little while to geta claw ready to cut. we ready to go? okay. were going to cut to an ...

>> and the power comes from the surface. so theyre relying on that to be able to move. relying on the communication link to be able to see where to move. and of course -- but anything that is fit with the thrusters are, which rovs are, and verticals are, you will kick up dust. >> right, that is one of the advantages of having human eyes down here. if youre looking you can see just how much sediment there is in the water right now. and we have these very bright lights. four of them on the outside...

Once were free and clear, were on our own. its not like were on some, you know, rope or anything like that. >> not at all. unlike an rov, the remote operated vehicle, we are completely autonomous. were untethered. theres nothing coming from the surface. our batteries are self-contained. weve got enough battery power here to last us probably 12 hours so were in good shape there. >> im not sure that makes me feel so great being down this long but already change of color you can see, don, very much...

Through. thats what they did with the -- >> martin, can you ask him to turn that on? >> chris? >> can you ask him to turn the cutting thing on? >> well, the thing is -- we have -- one of the cutting things we are going to show you next hour. this particular one right now is were kind of hung on a rock. were not in a position to do that. and then this is also realistically, some of the issues you can run into is when the submersible sets down, or rov, maybe it may be, the bottom itself can be a h...

Think would be difficult, but you have to move by inches here. this is just 2 feet in front of our noses, right here, and you can see how tough it is to get that box into the basket. i can feel the submersible moving while were doing that, so you have to deal with currents, you have to deal with visibility. it would be pitch dark out there, if it werent for the bright lights on the front of our submersible. but the point were making here, you have to move so slowly, because if you drop that box,...

This is just two feet in front of our noses right here. and you can see how tough it is to get that box in to the basket. i can feel the submersible moving while we are doing that. so you have to deal with currents. you have to deal with visibility. it it would be pitch dark out there if it werent for the bright lights on front of our submersible. but the point we are making here, you have to move so slowly because if you drop that box, if you make a quick move or watch what happens when we turn...

Here is visibility issues. visibility issues is something that very much could be a problem for anybody that goes down to that kind of depth we may be talking for that vessel. the airplane. >> certainly the -- vessel depths covered in the bottom with -- it is so soft that the slightest disturbance will bring up a dust cloud. and -- whatever devices used to poe down there, whether it be an rov or submersible they all are going to have vertical thrusters. when they thrust had thrust up, that is go...

Same area or at the same time. >> isnt it curious that two pingers, the frequency to be 3.3 on both of them? >> well, i wont get in to that because basically the analysis on that i dont think has revealed anything unusual. i might ask mr. levy if he has any information on that. no. okay. >> do you plan to move more pinger locate canners in the area to cover more territory? >> no, we dont. because as i have said previously, one of the important things about this sort of search is the need for com...
