break and re-evaluate. i think they re still focused on those pings. they believe, as i do, that those pings came from the black boxes. bill, what about you? i m wondering, we got word this morning that the bluefin was slowing down today. are we running that thing into the ground. well, i think it s getting tired. there s a lot of effort been expended with that vehicle and it probably needs some maintenance and i think the decision to change platforms and change location is a sound one. hopefully i agree with david. there s nothing else down there that those pings could have come from but one of the flight recorders. so you got to stay in the area. that s the best chance we got. we have the orion. michael kay, other possible
piece of debris from that boeing 777. right now, the bluefin-21 is scanning the ocean floor in the 14th mission. if the bluefin-21 does not find any debris, search crews plan to shift their focus slightly north. let s talk about this. we have cnn safety analyst david suecy and michael kay and a professor at embry riddle. what do you think of this possible shift north? i mean, is it all they ve got really? well, it s not only all they have, but it is it is the best choice that they have at this point. i think that they ve exhausted what they can do with the bluefin. as they shift north, it s going to be deeper. they re going to have to take a
resources, which would be your choice to assist in this search after the bliefin ends its work. i think really we ve got to look at the technology and what its constraints are. to david s point, you ve got to align the technology with the requirement. and if the bluefin can t get down to the depths in the last 5% of the search area, then it makes sense to go onto something else. in terms of the expectation management, the bluefin has only been really deployed for 12 days. the first part of the underwater search was all ping locator and looking for the black boxes and the pings. they come in amplitude and strength. they don t locate where the black boxes are. when they transferred from bluling it out of the pulling it out of the water to deploying the bluefin, right at that very
that s important to know because just like the search with the grid on the ocean, every time you find out that the plane isn t somewhere, that s relevant. now we hear another bit of information. they re looking into the food, david. why? we all know that airplane food is not great. why might it be suggestive of something more here? this shows how dedicated they are. they re looking at every aspect they can. food is a vulnerability on an airplane. i know it is for me. it s possible for any fair just intent. not everybody eats. to me, it doesn t seem like a common thing if i hear you on the restricted information. and i m putting a lot of hope on that. it s one thing to have tv people in certain places speculating. but for investigators taking
criminal investigation when they say they have no connection between the pilots and this event. david? the fact that there was a turn at hand, a human hand. however it was actually commanded. the fact is that this airplane had intent. it wasn t an automated thing. it wasn t a free flight that just decided to make that turn. do they know that? yes. they know it couldn t have been a turn on trim, so to speak, because of something that happened on the plane? it s not just the turn, it s the recovery from the turn. if it turned and continued to spiral, yeah, possibly no one s at the controls. it spiralled and continued to fly for so many hours. now, remember, it doesn t have to be proven that it s criminal in order to restrict information. i refer to use restrict because that s the technical term for
