To see whether what we are observing is something that is credible as a pinger representation, where we are. >> bill nye, as a science person, you want a controlled experiment, so to speak, to make sure that they are on to something and see where they come in. would you recommend that as well? >> well, if we have the resources. but as an engineer, i would say, if you have this datum from a couple of years ago where the air france pinger changed frequencies at great depth, its likely this one did...

The salinity and the surface temperature. you might get a difference in temperature between a lower layer and an upper layer and a difference in salinity, in density. and this would affect the path of sound waves. and so the two ping signals could very well be coming from a signal source. and with all the errors adding up, they seem to be very far apart. but if youre going to look some place, this is sure a very good start. >> yeah. jeff, we are learning tonight that the pings detected by the "o...

Assuming those pings were, in fact, from the two black boxes? >> the key is not to interfere with yourself and not listen to each other. you need a pristine environment. we talk about the chinese pings, its quite possible they were listening to their own ping, so first of all, you want to make sure theres not a lot of commercial traffic around that area and make sure you know the noise, understand the noise from your own ship and try to get the pinger itself as far away as you can. so putting an...

That it may not be a pinger signal. you just heard it and said look, it sounds like it is. are you open to the possibility that is not a pinger? >> it has to be something man made if it isnt a pinger. it just sounds and looks, the patterns look too much like a pinger to be anything else but. >> all right. so sounds like youre very confident. now, i know you have brought a ping were you very similar to the one believed to be on the flight. >> sure. >> as far as our knowledge, the one on the fligh...

And they want to make this point -- just because they think they heard this sound from one of their pingers down toings it doesnt mean that the plane or pinger is right there. it radiates so widely. it could be far, far away. so they will have to narrow down the search area these search teams to try to fine it. >> i appreciate the demonstration. i want to bring back david gallow. and former department department of transportation inspector. you believe these pings are from black boxes. is there ...

Would you recommend that as well? >> well, if we have the resources. but as an engineer, i would say, if you have this datum from a couple of years ago where the air france pinger changed frequencies at great depth, its likely this one did too. and with all the errors, its very reasonable the pinger would change frequency like this. but with that said, if were right at the limit of the batteries, 32 days, and youve heard nothing, maybe that last little bit you heard was the last little bit that ...

At least these next several days while we believe the two pinkers oig involved are still active. >> one of the many reasons they might not hear them is because the ocean is a noisy place. other sounds could be be drowning out any signals coming from the data recorders. rosa flores has become a bit of an oceanographer herself. what is going on causing the competing noises? >> i talked to several ocean engineers and we cant say its a loud place, but its definitely a noisy place. there are several ...

Environment, if you suddenly have several ships around there or aircraft dropping things in the water. we need to -- we just need to let ocean shield continue its work with the pinger to try and find another transmission from whatever is down there. >> mr. houston, if i can ask, you said yesterday that you actually heard the transmissions that were picked up, and what -- 10 seconds, 30 seconds? >> they sounded like an -- as i said yesterday, an emergency locator beacon. so, thats -- thats part o...

And youll be ready for tomorrow today. comcast business. built for business. we have breaking news from tonights news conference in perth. the search for the towed pinger locator goes on. a search that could take a very long time. rosa flores took a pinger out on to rhode islands narragansett bay to show some of the obstacles they may encounter in the indian ocean. >> reporter: this is what a ping sounds like. >> very high frequency. >> the critical sound searchers are hoping to hear in the de...

Now, with that said, apparently, the pinger is the thing that im relying on. apparently, it got all the way out there, with largely undetected. and i want to emphasize, we had a little dispute before the last break, in my experience, with airplane problems, its never just one thing. its a series of things. and so, this will all be, sooner or later, this will be resolved. it may be tomorrow, it may be years, it may be at this press conference at 11:00 eastern. but its very reasonable, as far as t...
