angel yus houston saying that to come to saying they found the plane without, as he says, i they ve been able to reacquire want to see some physical the signals they first detected on saturday not once but twice. evidence. when he says, i m optimistic he did note that the signals that they detect read noticeably we will find the aircraft in the weaker detected are not-too-don t future, i believe we re searching in the right noticeably weaker than area, not of natural origin, saturday s detections which would indicate most likely that the battery life on the black box pinger is expiring. electrical equipment, consistent it was set to actually expire at with fdr, it doesn t get much the 30-day mark. we re now day 32. more clear than that. being the military man, he s not going to go that final step so as a priority of of this until he has evidence. this is pretty much telling us mission, the ocean shield, the he s got it. david? yeah, ied that when the families are in consider
deploying the autonomous underwater vehicle. the better ocean shield can define the area, the easier it will be for the autonomous underwater vehicle to subsequently search for aircraft wreckage. it is important to note that ocean shield can search six times the amount of area with a towed pinger locater than can be done with the sonar on the autonomous underwater vehicle. searching under water is an extremely laborious task. so the more work we can do on the surface with the towed pinger locater to fix the position of the transmission, the less work we will have to do below the surface scouring the sea floor. given the guaranteed shelf life
saying, they are throwing everything they ve got at this over the next few days at least to try and maximize this window of opportunity and see what they can find. at the moment, though, wolf, they found nothing, they haven t managed to reacquire the signal that was detect by the australian vessel over the weekend, and that s of deep concern. we heard from the new zealand wing commander, who s in charge of the new zealand effort, that they ve basically given up hope searching surface area, anywhere near where the chinese pings were discovered over the weekend. they are putting all their eggs in the basket around where the u.s. towed pinger locator heard those pings coming from what they suspect those two black boxes. that s where the entire search is under way right now. are you hearing the same thing there? reporter: well, we haven t had a statement from the jack, the joint agency coordination unit that s headed up by the
compatible with dragging the towed pinger locator through the water. the t.p.l. has to be constantly moving so it doesn t drop to the bottom, but the bluefin to deploy it and bring it back, you have to stop the ship and lower it into the water, then you have to stay nearby the bluefin so you don t completely lose contact with it, so you really have to stop using the t.p.l. before you move to the bluefin operations. assuming the pings were the real thing and assuming the batteries die out, they haven t found the black boxes, haven t found debris, they are basically still searching for a relatively small area, a lot smaller than the air france area you were using, and it took two years to find those black boxes back in 2009 that air france plane that went into the atlantic ocean off the coast of brazil. they are only going to be looking, what, 50 or 75, maybe 100 square miles, right? yeah. it s a lot better situation than
over there, but we ll check back with you, matthew chance, in perth. thank you. let s bring back our panel, rene marsh, along with our aviation analyst, tom fuentes. peter, you agree with this notion they shouldn t put the bluefin, that drone, if you will, under water until they are 100% convinced the batteries of the two black boxes are dead, because that can interfere with those towed pinger locators. it could interfere, and they ve got to give the black box ten more days. if at the end of ten days they still have nothing, then they are going to have to sit down and reassess how they are going to map and search the ocean bottom in this new search area. would it make any sense or interfere if you put two pinger locators in that area? they ve basically narrowed it down to a few square miles,
