Air and still frustrating. Today back to square one. Debris sighted this weekend leading to dead end. Four items on a reconnaissance plane turned out to be Fishing Equipment and dead jelly fish. None of the items were related to flight 370. In an exclusive interview, they say theyre not giving up. How long can this be sustained . The search a ramping up, not winding down. Reporter i toured the ship this weekend as crews outfitted the vessel with an unmanned robot and black box detectors. The latest analysis has zoned in on this search area more than a thousand miles off the coast of perth, australia. Weve just got very General Information about where this aircraft has come down but nevertheless we are giving it the very best shot we can. Prime minister abbott refusing to put a timeline on the search as distraught relatives play at a buddhist temple in kuala lumpur. We owe it to the 239 people on board and to the whole world. We will keep investigating and we will never give up until we found out what happened to flight 370. Reporter i can tell you from being on the ocean shield and speaking to mark matthews, the one leading the search for the black boxes, he needs the search site to be 1,000 the sionethou the size it is right now, it is still way too large. Good to have you mary schiavo and david west, we hear that its intensifying, ten ships, ten aircraft out there. Still sounds like small numbers. Why not more assets involved . I think there could never be too many because of the cycles and shifts going on. You have daylight to worry about, the as much has to be done in grids, done logically and sequentially. Im not sure more is better in this case. Mary, thats something at that you point out that common sense doesnt rule in a situation like this. More is not always better. Why in. Because of what david said in part. You have to search in a methodical way. They literally have mapped out the ocean, have assigned different teams search areas and given the late date, more is probably better in this case because the pinger and while im always optimistic and the batteries dont just stop immediately on day 30, but right at this point we have to trust the australian officials and they say they have what they need. Frankly at this time and after so many weeks i would ask for more, id throw everything you could get in the whole world at it. The question was answered by giving the most sophisticated pinger locating equipment available. Finding something related to an aircraft in the ocean. Even when they find object, its difficult for them to say it might be part of an aircraft because . Because from the pictures and when they pull it on board, you dont automatically know what it is. They will know when something is from an aircraft because parts on an aircraft are very specific to aircraft. This craft being made in the United States of america, the federal Aviation Administration has to improve most of the parts on the an aircraft, the sea cushions are approved, the panels on the flooring approved, if it came off of a plan, we will know whether it is from a plane. For passengers the things that float are passengers, luggage, tennis shoes. They find it, theyll know. So now we get to the pinger and its not hype to say time is running out. Its a rule of thumb that you have about 30 days best Case Scenario that that pinger still goes off, that black box making a sound going off that can be picked up by equipment. Question to you. Why only 30 days . Its the same question the french government asked after 447. Not on askly asked but they demd it be changed to 90 days. New planes have to have 90 days. But theres nothing say they go have to be retro fit for 90 days. Ever get an answer on how the maintenance is done on these pinke pingers . Yeah. I have a high level of concern, because an inside source did an audit and checked the way theyre stored and the manufacturer recommends a cool and dry place for storage. If theyre in a heated area, it was a 120 degree room with high humidity. My inside source says the u. S. Was happy to give these asset to the search just like they did in air france but they did raise the question of why are you using it when you dont know where to look . You still have to be relatively quickly before you can hear it. They call it mowing the ocean and they have to go back and forth, except while theyre looking in one square, miles away in another area might be where it is. Without more exacting information, theyre relying on a little luck. Sometimes its better to be lucky. If they get lucky with towing the pinger, thats good. I cant see not using it. I understand the skepticism but, my goodness, at this point theyve just got to try. Im going to go with the australians on this one. And towing the pinker is like miles long so you want as little traffic in the area as possible. Thats why less assets can be better. Mary, youve made that point in the past. March 8th is when this started, okay . Still people dont understand why with all the snoopy sovereigns in the world that nobody picked up this airplane. Yes, the thai radar picked it up a little bit but with india right there and thailand right there and diego garcia that does nothing but surveillance, do we have more information on why people dont have information on this plane or do we think thats not coming out . We do have information. Once the transponder stopped submitting and you dont have the advantage of the more advanced radar and any tracking ability on this plane, youre down to basic, Old Fashioned primary radar, which is almost like what you see in world war ii movies, its just a blip on the screen. If nobodys watching the screen, if no one as paying attention, its like it didnt happen. Ive had cases in the United States where an air Traffic Controller fell asleep in the tower. If people arent paying attention and after about 20 minutes they can be looking at the screen and not noticing theres such a boredom fashion. It boggles my mind they pick up an email and they couldnt track a plane. Kate. Tensions boiling over this morning between north and south korea, the two sides exchanging fire at north sea after military drills spilled over the border. Barbara, what more are we learning this morning . Reporter good morning, kate. This is exactly what the u. S. Has worried about for weeks. Is is there a new round of provocation from north korea . This took place on the western border at sea, north korea conducting live fire exercises, some of it falling into south korean waters and at that point the south responded. The Reuters News Agency is reporting this got pretty brisk, the north firing about 500 artillery shells, the South Koreans firing back with about 300 shells. This has been an area of tension before back in 2011, a north korean torpedo sank a south korean ship killing 36 sailors. One of the big concerns is this comes just one day after north korea raised the prospect of another nuclear test. It goes back to the fundamental question is there an isolated incident or is this potentially a new round of North Koreans provocations . Very important question, barbara. Youre live at the pentagon. Thank you very much. Lets talk more about this with our chief correspondent jim sciutto, who is here with us today. Barbara is asking a very key question. Is this an isolated incident or ratcheted up provocation the u. S. Needs to pay more attention to . What are you hearing . Its clearly not isolated. Its one in a series of things. You had a threat last week to set off a nuclear weapon. Going back a few weeks ago, the excuse of his uncle, the second most powerful person in north korea and if you believe his stories, his children as well. North korea will always be provocative but the thing is theyre becoming unpredictable. I know from talking to u. S. Officials, even the chinese, their main ally, are growing uneasy and throwing their hands up in the air and thats a bad sign. Theres a little bit what can you do, right . Absolutely. You know what you can do but no one is willing to pay that price. That state does not survive without tremendous in flows of money, oil, food from china. The trouble is does china and the u. S. And south korea want to bare the cost of the regime. Theyre also worried about having u. S. Troops right on chinas border. North korea is a buffer between south korea and china. Is china willing to pay them, is south korea willing to pay them . It becomes an issue of containment. No one know what is his next move is. Thats the beg question mark. There is no communication with north korea and no way of knowing. The scary thing is he, the country, seems to be becoming more and more unpredictable. Exchanging live fire to me seems to be ratcheting it up. You hear a lot of threats, a lot of bluster and we always talk about the saber rattling, 500 artillery shells, 300 artillery shells. That sounds serious. Remember the north korean shell, south korean islands, civilians died in that. How does south korea then calibrate its response so you dont go to war. Its a real danger in that part of the world. The chinese used to be the best kind of communicator with the North Koreans. That was north koreas sort of red line to the world. For example, when the executions happened of kim jung ils uncle. You dont want to be surprised. You dont want to be surprised. Thanks, jim sciutto.

Today is the final day for obamacare enrollment. The white house is giving a weeklong extension for those who start enrolling today. The question is could obamacare come close to hitting its original 7 million enrollment target . Jim acosta is at the white house. Will they meet the number . Is it a magic number anyway . Reporter its been a bit of a magic number looming on the horizon, but they know since it was all those problems since the rollout, its been 7 millions. When they put out those numbers that they hit 6 Million People signing up by late last week, they were feeling pretty good about enrollment numbers. Over the weekend 2 Million People went to the web site and 380,000 people went to the call centers. When we get the final enrollment numbers in a couple of weeks from now, they could be in the neighborhood of 6 million to 7 Million People and that is going to be considered an achievement here at this white house. We dont know exactly how many people have paid for the coverage and the percentage of young Adults Signing up. They need 30 to 40 to make this program really sustainable. One thing well be watching over the next several months is the sticker shock, are people seeing premiums going up . If so, this program could become a liability again for this president. They are trying to get the word out. Vice President Joe Biden will be on the rachael ray show later to talk about obamacare. Theyre in the home stretch but feeling good. Are there enough people . Dominos fall. Are there enough young people . Dominos fall. One thing we know for sure is the need for health care is ever increasing because of the winter that will not end.

We talking about blizzard conditions, about a million of you through minnesota today. Yes, its exiting to the northeast but look at the tailing cold front behind it. This means more rain in the forecast again. Its going to teake its time as it moves through the ohio valley. As we go through about the middle of the week, we have the setup for a threat for severe weather. Were starting to see a little bit of that spring setup. Snow has at least switched to rain so its about a hint better. It was wet this weekend. It was ugly. You can say it. Less do with the hair when its raining because everyones hair looks bad.
