The important part is in the preplanning and that's what they were trying to get together in the initial stages of looking for these pings. >> no doubt. >> looking, the example that's been shown than extraordinary. and we're all getting some very interesting lessons in oceanographers and acoustic sounds. what we're seeing at the moment in this very small search area, not the large one but the very confined one, we're seeing the ocean shield go through with the pinger -- towed pinger locator. it does a sweep through and then exit the search area and then hms echo comes in behind it and it's doi...

Let's discuss with our panel now which includes audio expert paul gensburg and jeffrey thomas, managing director of airlineratings.com and david galoo, fabien cousteau and that british guy, michael kay. jeffrey, i want to start with you first. if not now, when? seriously. many people are asking that. jeffrey? >> sorry, john. yeah, look, it's a very good point. and one of the things that we possibly are under playing a little bit here is the role of "hms echo," the graphic ship because that is surveying the bottom with an echo sounder and the bottom as we know is silt and they're hoping for a s...

Kilohertz. >> tom, what else could be making the noise that was detected for two-plus hours two days ago? what else could it have been, if not the black boxes? >> well, there's -- as i said, there's a lot of things that are in the marine space that emit, that put acoustic energy into the water at 33 kilohertz. probably the most common is a thing called a single beam echo sound. it's used on ships to find the bottom. it is able to detect the bottom of the ocean very deep in the ocean. to do that, it's putting as much as 1,000 types more energy or it's 1,000 times louder than the pinger is. so e...

Are they damaged? we just don't know. but the only thing that we do know is that we have a lot of equipment in place to listen for these pings. we have a british submarine, a british ship, both of those equipped with sew that are equipment. we have the united states navy pinger locator listening for that ping noise. and i wanted to take you inside this charter fishing boat that we are at. we about 1700 kilometers from the search area. i wanted to show you. lots of boats have technology that uses sound to basically scan the bottom of the ocean, even a charte fishing boat like this. i want to sh...
