lot, lot smaller. how much smaller is it based on the fact that those pings were found about, what, 17 miles apart? >> well, you know, we're giving the towed pinger locator a 1 to 2 mile detection range and actually it might be a little bit manufacture because of the altered frequency that we're hearing. the water actually absorbs that energy less, so the sound can travel farther. so maybe the tpls can see quite a bit differently farther than we expected. but at any rate, let's say you gave it maybe twice the detection range so they could see 5 miles, then the pings we have detected are 17 miles apart and and add another 10 miles, we're talking a 20 to 30 mile square area. that's significantly smaller for the air search area for the floating debris. >> having said that, eric, if you take a look at 20 or 30 or 50 square miles, 3 miles deep, finding those two small boxes, that would be pretty difficult.
