right, fabien? >> you described it correctly. it's not like a gps pinpoint. know, sound travels much faster underwater which makes it that much more difficult to triangulate, as miky said, where this ping is coming from. then you the complications of water, temperatures that bend those sound waves, as well. so it's much more complicated than what it sounds like. and then you've got, of course, the limited range, these rovs and auvs like the bluefin have in the case of a bluefin, maybe 24, 25 hours of time at 3ish knots which is actually fairly slow. it's like trying to find a needle while you're taking postage-size pictures of the bottom in a field the size of long island.licatecomplicated. >> paul gensburg, audio expert. does it concern you that we haven't heard anything in four days? >> well, it does. it really gives us an indication that we have it looks like come to the end of the lifetime of the batteries. certainly hope springs eternal, we would like to hear them some more, but right now, no doubt, all of the engineers aboard the ship are doing an analy

you mentioned, fabien, you were uncomfortable because this is a small sliver of evidence but it's the best evidence yet. i guess the other evidence would be any sort of physical debris or wreckage from the airplane which we have found nothing and we haven't heard anything about any visual sighting. no one has mentioned a visual sight r sighting since last saturday. >> a lot more questions than answers. as far as the basis of knowledge it's almost nonexistent except for those four pings. if we could find physical evidence floating we could track it back through the currents and everything else to a general location and that would certainly enhance the -- the idea that the area is a quantifiable, qualifiable area. or if the sonar, whether it's the bluefin-21 or other would pick up a nice trace at the bottom of some object that would really give us a good visual on that possibility, i think that would make it a lot easier. >> mary, you know, i was talking to les abend in our last show, les actually did his real job this week. we actually took a -- flew to london as a 777 pilot and he sai

. >> fabien's not going to go into the legal aspects, john, but you can.could address that. also back to the number of people who have been arrested. if so many people are responsible, does that mean that no one's responsible? it seems to me that one or two people would be a greater focus perhaps. would put the responsibility more squarely on someone. >> there's no question the captain has to be the focal point. he was the person in charge. he's the one who should have given the evacuation order much earlier. he has to be the focal point. they also need to understand how the cargo was loaded. how it was stowed. how it was put in place. whether it was properly tied down. they have to understand the stability of the vessel. and whether the vessel was built properly for the sea conditions it encountered. >> certainly several bodies, still other 100 bodies need to be recovered. those efforts continue for quite some time. john and fabien, really a delight to have you both here. >> we should say, of course working on the mission 31 expositi exposition, a very ex

coming up, we'll ask ocean explorer fabien cousteau. [ male announcer ] this is jim.ho doesn't stand still. but jim has afib, atrial fibrillation, an irregular heartbeat not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto jim's on the move. jim's doctor recommended xarelto. like warfarin, xarelto is proven effective to reduce afib-related stroke risk. but xarelto is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem that doesn't require routine blood monitoring. so jim's not tied to that monitoring routine. [ gps ] proceed to the designated route. not today. [ male announcer ] for patients currently well managed on warfarin there is limited information on how xarelto and warfarin compare in reducing the risk of stroke. xarelto is just one pill a day taken with the evening meal. plus, with no known dietary restrictions, jim can eat the healthy foods he li

thank you very much, fabien cousteau. it. >> thank you. >> sure. >>> if you're heading out this weekend, plan accordingly. thunderstorms could be headed your way. the easter forecast is next. >>> but first, their children one step away from being homeless. we're talking about motel kids. families can afford cheap motels, they can't afford a decent meal. bruno has been serving pasta dinners to hungry kids in california, and now the cnn hero has reached an impressive milestone. >> please join me in honoring cnn hero bruno serrato. >> reporter: when bruno was honored in 2011, he was serving pasta to 200 low-income children in anaheim, california. >> the pasta's ready. >> reporter: since being rewarded, his program has grown significantly. >> who like my pasta? >> all: me! >> now, we are 1,000 kids a day every single day, monday to friday. >> reporter: reaching kids in three more cities in orange county. >> each time i prepare a meal, each time i serve a kid, i know i give security to a little kid and a full stomach before he

. >> i want to bring in fabien out in california, now that it's 5:00 a.m. make sure you don't fall asleep on us. there's a gubernatorial race in california this year. jerry brown is running for re-election, cash kashkari, the republic kwan, will be his opponent. voters have shifted so strongly to the democratic column in california the last 20 years, have really helped make that state one of the bluest in the country. the discussion we're having here, though, potentially the reputation of the deporter in chief reputation manage latinos, are you finding that is a problem for the president, a problem for your party in california in terms of engaging with latino voters in particular? >> well, in california, a little bit different than the rest of the country. we in new york have a lot in common in that respect. we don't have strong republican challengers, not for governor, not for u.s. senate. in fact, most of the house, the state legislature is in democratic hands. but i think the president does have a very, very serious problem with respect to how they manag
