That was 5,000 square miles. for the tpl, the tow pinger locater, that's an awful lot of commercial traffic in the area and i'm assuming the team knows enough to be able to clear some of that out so they can listen appropriately. >> what you're saying is despite the fact that we say these are shallow waters easier to search for flight 370. there are reefs there. they're their own challenges in the search. >> many the surface noise, sometimes deep water, one of the few advantages is you can get below the wind and the waves. in this case you probably just can't. there's going to be constant wave...

>> that's right, we still are flying over the search area, and, of course, we still have the bluefin under water still searching. it is an important juncture right now. we're in the transition period, and i'll call that the transition from the tactical precision search to a more long-term search, and i say tactical precision search, and that's around that circle with the radius of about ten nautical miles. that was really focused on the area where the t.p.l. had that really long period of detection about two hours of detection a few weeks ago. so i call that a precision search, because we had ...

Think they are in -- the right spot? >> it does. that goes back from the sources i have talked to. it goes back to the confidence that they have in those ping -- very first tplping set they got which was the two miles of tpl. it is not just that they received the ping at that frequency. but it is that they received the ping at that frequency of varying amplitudes which gives you an indication not just where it is as far as the general area, but you can hone in on it a little bit as you get further away, amplitude decrease. >> thank you so much. coming up, as rescuers frantically search for s...

Happened on flight 370. everything so far is a small piece of the overall picture. >> pamela, appreciate the reporting. back with our panel. this is probably a dumb question -- maybe david gallo, is there any value in retrieving cell phones from the depth or probably not? >> i have been meaning to check on that. it seems like not but it is part of -- if there are clues to be had it is worth doing. i don't know the answer to that. >> it is interesting the bluefin searched 90 kilometers which is a small area. >> yes. we were warned that was what it with was going to be. it takes it six times a...
