Enhance your reception. >> thats why he says, les, here is a thing that says shape of the pulses. because if you cant hear it, then there is a certain shape whatever the instrument that is picking it up. >> i wanted to get a visual picture what these folks are doing with all this instrumentation. theyre not actually hearing something. theyre more than likely looking at a visual. >> theyre watching it. thats right. >> and you put together, there is another -- i dont know if you have another graph...

"ocean shield" has detected a beacon of the black box. >> reporter: this is nearly 1,000 miles off the coast of australia where two sets of electronic pings were detected 15,000 feet, more than 4,000 meters down. the position needs to be adequately confirmed before this submarine is deployed to get a visual. >> this is being done without finding any wreckage thus far. and i think its quite extraordinary. and what id like to see now is for to us find some wreckage because that will -- that will b...

Nothing. im curious how relatives are responding to this news? >> its been a roller coaster ride for them. and they have had their ups and downs and their desperations today, some were already saying with this news, i have lost hope. others hear the news and they want to believe it and they say, im not convinced until and unless we get that evidence that we heard there from the air marshal, houston telling us that it will take several days before they get a visual on the wreckage if theres wreck...

Visual of the wreckage. he says hes more optimistic now than he was a week ago. this is quite an extraordinary set of circumstances here but theyre still trying to refine and define their search. the wreckage, by the way, which is what theyre actually trying to look for, theyre hoping that the pinging information can built up a sound leading them to a visual identity. here is the problem, time is running out the life of the batteries are one day past advertised shelf life of 30 days. theyre hopi...

Visual, but obviously the less cloud cover the better. visibility right now about six miles, so the conditions are fair for the search today. >> nick, you know you have been with the families. youve reacted with them. youve been telling their stories. how did families react, how do you think theyll react from hearing angus houston? will this news conference on this sub sea search honing in a smaller search area, will that give them hope? >> reporter: it will. what theyve been looking for is prof...

The season. and thats going to be a real problem. its sort of one step forward, ten steps back. because these waves and these conditions, you cannot -- you cant see, which is what theyre still trying to do, find a debris field and have a visual. >> 8.5 meters is 25 feet. these are waves that are like buildings. like trying to peek through the streets of manhattan. >> its horrendous and makes it impossible to go even further, if they were to find a debris field than to launch any. >> so if you we...

They can drop lower. they can get a scan with their el electro optical camera. or they can use binoculars. dont underestimate the power of a person using the binoculars to get a visual. because the weather has been challenging australia had to scrub the mission two days ago. so hopefully they will have better weather which will help them search. >> we certainly hope so commander marks, with the uss blue ridge, you have spoke to us many times through this agonizing search, we appreciate your time...

Never find the black boxes. and without them, we may never know what happened. >> tom, the satellite photography is amazing to me, the fact that so many countries, including thailand have this kind of technology. w have we yet had an airplane spotting of what was picked up on the satellites yet? of all these efforts through all these days. >> no. >> no? >> nope. and in fact weve had individual planes and pilots say they thought they see something, but theyre whipping by at 200 knots per hour. by...

Little piece of an incredible international effort. >> can you give me a sense of what its like out there, given the varying weather conditions? how low are the aircraft flying to actually try to get a visual on debris? >> sure. yesterday as you know was a pretty rough day for environments here for the weather. but these planes, at least our planes and the u.s. navy, its an all-weather aircraft. and so the the pilots are the best in the business. but the people in the back, those tactile coordin...

So starting with what youre getting from the hydrophone. >> right. and so the hydrophone, you could just put a headset on and listen to the hydrophone and listen to the ping, but you also have a visual display, where youre looking at the actual sound coming out of the ocean. so this is ocean sound here. and theres some noise source in this particular part of the frequency. but if you were there with the pinger, you see a really sharp spike at the spot where the pinger is. so once you got within ...
