some headlines coming out of that. as you mentioned there, they had those four pings that they were able to confirm. that helped them narrow down the search using that u.s. navy towed ping locator. well, they haven't had any pings since tuesday of last week, and it seems they just decided that they're not going to get any more. those batteries have gone down. so, they move on to this new phase, and they're going to put the submersible, the bluefin, down into the water this hour. we were told it would go in at the top of the hour, so it's probably happening as we speak. and that starts this new phase. it's going to go down, we're talking 450,000 meters down, over 14,000 feet down below the surface, and it will go at walking pace, mapping the surface, the ground of the ocean, the ocean floor, using side sonar. it's a real 3d image of what's down there. they're hoping, of course, to find any sign of the malaysian jet down there. it's going to take them perhaps weeks or even a couple of months
