u.s. military. are they just right now hoping they have a hail mary and they re going to find something, is that what they re about to do? no, i think they still as tom mentioned, they trust the mrsat data. they just got the look over the entire arc and they re starting. is there anything else they need down here if they re going in this whole area? the underwater search, that goes very, very slowly. think about somebody walking along all of the state of indiana, how long that could take. when they finally found air force 447, they had three rima 6,000s plus a towed array, so they need to bring in some more equipment quickly. the air france search which went on for two years, after five days, they did find wreckage. so they at least now where approximately the plane had gone into the atlanta ocean. this was a two-year span, but
there now looking? it does the same thing as far as collecting sonar images. but it is a towed array. meaning you have to let it out on a cable. and if it s three miles deep, it s going to have to let over ten miles of cable out to get to the bottom and tow it. so it can get stuck on things? if the terrain down there is rough, it doesn t view the bottom as well. it doesn t contour to the bottom where the auv will stay with the bottom and get you much better imagery. and it does have trade-offs. everybody thinks because it s down there for 24 hours. sending up real-time data. it has to turn. when it goes to turn, it has to reel everything up, driveway upcurrent, and that could be more time than it would take to turn an auv around. so they might not be getting as much data. and the data coming up on that wire, yes, you re getting it as it s happening but losing resolution as a trade-off for that? a lot of these things they say they cover 3,000 meters. but if they do coffer
peter, they are two-thirds of the way through this relatively modest search for the bluefin-21. let s say in the next few days, two or three days it should be wrapped up. they come up with nothing. no piece of wreckage, no black box, nothing. what do they do then? they go back to the drawing boards to see if their initial calculations identifying this area were correct and secondly they start to reach out for different equipment. probably a towed array that will help them monitor and look at the ocean floor over great distances. we heard a navy spokesperson say a while ago that they are beginning to think of new strategies, new plans through july if they come up with nothing right now. additionally that part of the ocean has turned out to be deeper than they first thought and the bluefin is at the limit that it can go down. so they are going to need equipment that can give them
length, you have to do it with a towed array. you have to do it with a new vehicle. and you better start lining that up now. i assume they ve searched a much wider area on the surface with the planes and the ships, right? that s proven negative, so they found nothing from doing that. again with looking at a wider area of search, they re assuming that it s in this area, not just on the pings, but also the fact of how much fuel they think that plane consumed based on their guess at altitude, their guess at air speed, you know, so really they re going by the pings in the water and that s the best way now to look. because, peter, earlier in the week, we heard malaysian officials, australian officials, including top leaders there, suggesting they re going to wrap up by this weekend presumably the aerial search. you don t think necessarily that s a good idea? well, i think you ve got to keep searching until you find something. but they ve got a lot resources developed on the air side
