Surface based on any of the models predicted for the currents. wheres the debris? i suspect most is at the bottom of the ocean. >> day 38 now. seems to be frustrating and searchers have to come up with a new plan. hoping to find debris. but is this also predicated on the fact theres no pinger sounds in five days and so this really is the only recourse to continue to search or widen the search on the surface? >> fredericka, i think you have hit it on the head. they might as well keep looking for ...

The word -- confident, p beyond cautious optimism. he is putting a brave face on what investigators learned so far? searchers learned or is there real reason for confidence based on the pings they detected? >> i dont think there is my other plausible explanation what those noises would be. some scientists use these devices, put them on animals and so forth to track them. if a scientist had left a pinger there that was ping that way and hadnt raised their hand by now to say it was his or her proj...

Hes turning the scientific mission into a movie. >> its that need to see whats there beyond the edge of your lights. to see the unknown for yourself. >> reporter: the pressure at nearly 15,000 feet is crushing and very few manned submarines can with it stand it. >> only a half a dozen subs that can go to basically half the ocean depth with a number of countries having that capability. it gets to the point of, of collapse. it basically implodes. it just crushes. >> reporter: finding the plane is ...

Is all happening around the clock. as far as we know theres been no debris or suspected debris picked up and analyzed recently. but talk to us about when we may see this next phase, when they be deploy that underwater vehicle to possibly go towards where these pings are coming from. we know the batteries last for 30 days. in some cases the batteries have lastest longer, could we see this phase begin in the next few days? >> reporter: its possible, yeah. tomorrow will mark one full week since wev...

The one flying the aircraft. then the captain is catching all of the radio signals. >> thanks. thats insightful. colonel christensen, thanks. kissing congress member on the ropes apologizing for his actions. and the man who made the pinger of flight 370 joins me. does he believe the black box discovery is at hand? at od, whatever business youre in, thats the business were in. with premium service like one of the best on-time delivery records and a low claims ratio, we do whatever it takes to...

The bluefin-21 is deployed? the underwater drone? how small would you like that search area to get? >> in an ideal search if were getting a steady signal from the pinger, we would continue to use the tpl until we narrowed that search area to where we were confident we could triangulate to within a couple of hundred yards. >> couple of hundred yards, right now theyre at a thousand square miles. >> the tpl is the tool to tell you where to begin your search. and at that point you would move out to ...

Properties of the seawater and other geological obstructions or debris. the pinger could actually be tucked in under a piece of debris. it could be channelling the sound away in one direction. also, the sound under water can be tricky. the sound wants to always bend toward the area of the least sound velocity. so after you get near the surface of 1,000 feet, these can wreck havoc on your acoustic signals. if you are directly above the device, you have no angle of incident. you can go straight th...

Between the top and bottom. by some theories, particularly with lower sounds, it may go many, many, many miles before it comes out. this may explain why a pinger that shouldnt be heard more than three miles away is being located at a range of some 17 miles. as its coming up, its possible that these anomalies, these strange things that happen to sound in deep water are affecting that signal. and theyve got to overcome that and crush it down to the actual location before they go under water and st...

My question. >> as they proceed through the search area, they are towing this device behind them and trying to triangulate the signal. as fred said, you could have a lot of things going on with the sound properties and acoustic signatures of that device. there are a lot of things. we dont know what is going on at those depths. >> mr. patel, the battery is at the end of the life span. what is the longest your product can survive beyond 30 days? i understand you have a fix for this that could take...

Characteristics of deep water. and they present some real challenges. among them, something called the sound fixing and ranging layer. this is about a half mile down. its a naturally occurring portion of the water where sound travels less quickly than it does below or above. a lot of different reasons. the salinity level, water temperature, and this is the result. sometimes because of this layer, a sound that may come up out of here can hit that slower area and be bent at a very substantial angl...
