gone by now. and richard, too, to the point of commander marks, once they take the tpl out that is it. they will err on the side of caution. yes, i think that would be where i would divert slightly from yourself, david, with respect to that. because angus houston said there is no second chances. so i don t see the urgency, i m not an expert in this, but from what i have heard from the experts i don t see the urgency to get the bluefin into the water searching other than obviously the resolution of the issue when you can just, another day or two, to make absolutely certain. so i can see o david gallo, i mean, as slow as the bluefin moves as commander marks was saying for an area this big how long would it take before they have an accurate picture of what is on the ocean in the ocean depths,
and then taking a picture. and then you have to process all the information. and then remember just to turn the ship around takes hours and hours. so you know you could be towing the thing for a couple of miles behind you. you have to reel it in and get it on another reciprocal course. so this is by no means a fast process, a very slow process. commander marks, always good to have you one, we appreciate the work you and everybody else is doing. and our panel joining us, david souci and david gallo, and richard quest. david as you look at where it stands today as opposed to yesterday, what do you see? well, as richard pointed out, i think it is time to put the bluefin in there. they haven t seen anything for two or three days. i think they re pretty much done with looking for that battery if they haven t heard anything right now. because remember they re searching in the area that they had the signal before, and they haven t received anything. i would estimate the battery is
search with the tpl for now. commander marks, good luck with the search, thank you so much. let s bring in tim taylor, sea operator, and david souci, analyst and author of the book why planes crash they re here with me. and cnn analyst, miles o brien. tim, i want to start with you. the fifth ping is building confidence increasing the data map that could bring the searchers to the source. continue the pings, as long as you can get ping. the av work and ultimately rov work on this site, we have forever to do. we have limited days or hours as commander marks said on this. so get as much as you can until it stops because you can t go back. and once they stop with the towing the tpl and they start the av operations they can t do one or the other. so you can only do one of those. it is not like you can do these simultaneously from that platform. david, what do you think?
for the boatteries. so you search as long as you can? we talked to commander marks and he said he expected from the time they stop receiving the signals, the assumption that the battery is gone, they would continue to search for at least two more days after that just to be certain that they ve gotten, as mary said, all the juice out of the batteries that are available. i still don t get the proximity related to the ping pickup. the prime minister said within a few kilometers and now you tell me the search area is the size of new hampshire and new jersey together. i don t get it. there s two things. the search area, still looking for debris. when they talk about large search areas they re talking about debris, not necessarily where the black boxes are. the search for the black box is much smaller than that. in fact, if you included all the pings you would still be within about 500 or so square miles is the area for the black boxes. now, if you then exclude the extraneous pings, re
a margin to last longer than 30 days, let s say the minimum is 30 days. right now, we really don t know. each of them depends on how long they ve been or how they ve been stored, how long they ve been on the air frame. at this point, you re still within a wento where you could detect things. , davi david, at some point, investigators have to decide that we re no longer in a listening mode, we re in a looking mode, and we re going to have to rely on our eyes and our cameras to do the rest. when is that decision made? when they ve just gone too many days without a sound? pretty much. it s driven by when they ve received the last ping. commander marks told us once they stop hearing those signals, they ll go two more days. after they ve gone two more days, they ll assume the pingers
