If at all possible, you don't go past that depth rating. you want to keep the equipment safe to continue the search. >> so it is lost forever then. it defeats the purpose. sylvia, what about a manned underwater vehicle? china has the "sea dragon." it can go to 7,000 meters underwater. most of the passengers, most were chinese. why isn't the "sea dragon" out there is the question? >> once the target is found, deploying manned systems an remotely-operated tethered vehicles to actually recover equipment makes sense. but to deploy the "sea dragon" or any of the other deep submersibles that exist -...

Would implode, and you lose the tool that you're trying to search for, search the debris. so you know, if at all possible you don't go past that depth rating. you just want to keep the equipment safe to continue to search. >> uh-huh. and so then it is lost forever then and that defeats the purpose. sylvia. what about a manned underwater vehicle? most of the passengers on board say -- most of them were chinese, why isn't the sea dragon out there, is the question? >> well, once the target is found, deploying manned systems and remotely operated tethered vehicles to operate equipment makes sense....

We will see more mapping of the ocean there are. >> are these deep towed sonar devices, are they widely available or is that a massive investment? >> it depends on the depth rating. you know, for this kind of depth, down to perhaps 6,000 meters or 20,000 feet, there are around eight of these vehicles in the world. they are in industrial use most days. and they are capable of swath widths of, you know, two or even three miles. so, very, very powerful machines, but of course, they are only of use to people who have the specific need in mind to go and find a single target on the sea floor or to m...
