The south indian ocean. Remember, the shelf life for the batteries in these black boxes are about to expire. This comes as australia takes charge. Lets bring in Matthew Chance live from perth, australia. Matthew . Reporter thanks. Were in a new phase in the efforts to try and find malaysian flight 370. Probes search beneath the search to find the missing airliner. Today, the underwater search begins. Two naval vechl vessels now on location scouring a 150mile track. The unmanned underwater robot and black box detector, Australian Authorities say theyre confident. The area of the highest probability as to where the aircraft might have entered the water is the area where the underwater search will commence. Reporter but the ocean shield is working against time. We are now getting pretty close to the time when it might expire. Reporter today, australia announced theyre a partner in the investigation with malaysia and theyre taking the lead in the search. This as 14 aircraft and nine ships are on the lookout for large objects that may be related to flight 370. Were looking for Something Big. Unfortunately all the leads we got from the satellites turned out to be other things. Reporter australian Officials Say they are hoping still to find some kind of debris from the missing airliner. They still havent found even a trace of flight 370. It sure seems its all based on guess work still at this point. Australian authorities admit the location theyve chosen to certainly is based solely on the best data available. Lets get back to will riply on a boat monitoring the ocean shield. Reporter we know this search with the admission of this new hightechnology is now an on going job. Weather conditions fair today similar to what were seeing here just off the coast of western australia. The search zone about 1,000 miles from where we are right now. This is what they saw. No white caps for searchers trying to get a visual spot of some sort of debris. The weather has been so unpredictable. So searchers are doing what they can with the conditions that theyre facing as they continue hunting for includes in the disappearance of flight 370. Kate . Thank you very much. Lets bring in mary schiavo to talk more about this. Also, david suici and the author of why planes crash. Good morning to both of you. A lot to work through again this morning. I have to say, i have a lot of questions for you guys and im not sure there are any answers at this point. So we now have this new specified track that these ships are converging onto search and to begin the underwater search. This wasnt going to be done until they had found something concrete, mary. Why are they doing this now do you think . Well, because they havent found anything concrete and theyre very afraid and concerned that the batteries on the pingers may run out. They will know for a fact that the batteries will have died and never had a chance to put those pinger locaters in the water and go to work. No one would rather that those pingers just sit on the shore. Thats absolutely right. The man in charge of the joint coordinating effort of this search, he said that this is the best area of highest probability as to where the aircraft might have entered the water. Thats why theyre going to be focusing their efforts there. We dont get a good sense of what they told us what theyre basing this on. What do you assume theyre basing this latest decision on . I think what theyre doing, kate, is trying to narrow down the assumptions. Theyve accepted the math and that it can work. As you vary the assumptions, it varies a few points along that track that its on. It refines it a little bit more because youre ruling out certain speeds that the aircraft might have been. For example, if its going 450 knots, it would be this point, 400 would be this point. When it shifts, it means to me theyve exhausted those assumptions, not necessarily that they completed the search in those areas. Lets go onto the next assumption and see what that brings us. Bringing the search area up to the direction that its going now. Im pleased that those pingers are in the right place and moving forward. Mary, theres a reason that they havent deployed these assets quite yet. There are limitations to what they can do. Does this feel like a hail mary pass at this point . Well, somewhat. Certainly for the sake of the families and the sake of the investigation, you wouldnt want to not try it. Yes, they didnt use them up to this point because they didnt have any debris field. Without a debris field, its a bit of a hail mary. Sometimes, as the old saying goes, theyd rather be lucky. At least they have them in the water where the best information they have are. Beyond that, there really isnt anything better you can do. The hail mary is probably fine at this point by many folks. The australians are also saying theyre very unlikely to bring in another pinger locator at this time. Why dont you throw five at this . Wouldnt this also increase your chances . What do you think of that . I think it probably would. But at this point, the times limited. All the assets theyve asked for and put there are there. I think they expected to have some kind of debris field at this point. At this point, the assets that are there weve got the wheels on the ground in other words. Im encouraged by the fact that least were moving forward with the investigation. The families are the ones who really need encouragement and answers. I want to lean on your expertise in that area. You represented families afterdy sasters. The families now asked to hear communications between the cockpit and air traffic control. The investigators have denied that request. What do you think of that decision . Do you think that the families deserve to hear that at this point . Yes, absolutely. I think theyre mistaken in not giving the families all the information that they have. Its easy to sequester the families, put them in the room and play the tapes for them. After september 2011, that was done. It was tough on the families and anyone could opt out, but almost everyone wanted to hear it because they want to know. And i think thats their number one desire, they just want to know. It could be handled very effectively and discreetly. By denying them that, theyre going to have more and more questions and frustration. Thats been one of the constants weve been hearing from the families from the very beginning of this. Well be back with you. Thank you. We have new information for you about the shooting at ft. Hood. There are strong indications an altercation with another soldier is what sparked the violence. Were also learning more about the shooter and piecing together his past. George howell is live at ft. Hood with the very latest. Reporter the more information we get about lopez, the more you start to see these two personas juxtaposed together. Investigators are looking at a mentally unstable man who went on a shooting rampage. They are saying it could shed light on the iraq veterans motive. Theres a strong possibility that that in fact immediately preceded the shooting. Reporter but Officials Say theres no indication he targeted anyone specifically. We also know lopez was undergoing a variety of treatments for depression and ptsd. Doctors prescribing him ambien and anti depressants. Coworkers are in disbelief. He was one of my best soldier in the organization. Reporter lopez, his wife and their 2yearold daughter lived in this apartment. He didnt seem like, you know, the type that would do what he did. Reporter another neighbor was with lopezs wife the moment she found out the shooter was her husband. She just broke down. I did what anyone else would do. I ran and i comforted her. Reporter around 4 00 p. M. , lopez opened fire killing three and injuring 16. The gun purchased at the same gun shop where nearly five years ago, major nadal hau san bought his gun.

Theres a lot of buyers for a house like yours. dad thats good to know. mom im so excited. Welcome back to new day. Ft. Hood, its one of the most secure places there is. Or is it . Its a legitimate question right now because of the combination of the community and the soldiers dealing with deployment. Will that make it unsafe no matter what they do . These are all the questions that were dealing with right now. Lets dig into it with retired Major General spider mark. Hi, chris. Good morning. Yesterday, we discussed that this seemed to have been an altercation between the shooter and someone else that got out of control. Soldiers are going to fight. Theyre regular people. Theyre going to get into it with each other like anybody else. What is the protocol when Something Like that is going on . Leaders jump in and say break it up, dudes. Lets act like adults and lets get about the task. Your emotions might be on the surface, but like anything else, if you if youre not mature enough to handle it, leaders need to jump in, break it up, go to your corners. We can settle this some other way. I ask because theres been a suggestion that it got out of control. So the question is, was there anybody there to stop it. What does that really tell us . Thats not telling us so much about the specific event, but it goes to the general question about whether or not these changes that were supposed to be put in place at ft. Hood after 2009 were. There was a lot of red tape that came into play. What is your basis of understanding as to whether or not they did what they were supposed to do to make the place safer . The army and the military has this thing called a standdown. In an event like this, nidal hasan back in 2009, the army has a standdown and everybody gets involved. They try to figure out what went wrong. There are multiple results that come from that. Its a multi layered report. Its like crowd sourcing. I need to tell you, 2009, there was a full court press to get it right. We were getting at particularly protect during that time. I dont think there was a budget issue that followed that that might have caused the folks at ft. Hood to take a recommendation and put it off to the side a little bit. I think they jumped on that. And it was across the army. In this particular case, i think were going to find out as you have a very troubled young man able to put a weapon, legally purchased downtown and bring it on post. Because his car was registered, he was a soldier in good standing. The real issue is what was his mental condition. Thats right. How are they checking, whats the responsibility of those people, and how are they able to communicate what they know to others. The military needs to work on its ability to identify potential threats on basis. They should coordinate with the fbi to learn how to identify threats. Have stricter vetting for people seeking access. There was a question on how well they were able to implement these. We have to do better at monitoring people that are mentally unstable to make sure theres a safety net there. Absolutely. Weve labeled it ptsd. Is this a disorder or is this an illness or is this a wound . Arguably, the military is when youre deployed, its traumatic and its stressful. Do you have a very deepseeded illness that needs to be addressed across the board . We have rules that are difficult to gain that access. In this soldiers case, this is an example of where the system worked. He selfdeclared he had a problem. He was in the system. He was being evaluated. He was in the process. The protocol was wrapped around him. Sadly, we couldnt accelerate the diagnosis so that it was posttraumatic something. Its important what we label things. Were going to talk to a forensic expert, a psychologist expert who worked on the hasan case about whether he thinks the period of review are adequate with whats going on in the military. This shooter, he was under evaluation for a long time for ptsd. This had been going on since 2011. Right. So were going to cover that side and see whether or not the safety net was in place. How that translates into what we know happens in the rest of society. The suicide rate, yes its during wartime. From 2004 to 2008, the rate has increased so many fold more than it has the rest of society. Yes, it was during wartime. But thats something we have to deal with. You could look at this situation as a suicide. So were going to be getting into those issues. One of the solutions is what i want to end with. There are going to be calls that the troops on base should have weapons and if they had, this would have stopped sooner with less bloodshed. Do you agree . Absolutely not. That would have exacerbated this. You would have had more casualties. Folks driving by in their cars. I dont know whos making this recommendation, but lets have a conversation with him. No. Bad idea. Once again, the name guns galore. Thats where the last shooter in 2009 got his gun. Now its happened again. Not the gun stores fault because they didnt know, but something we have to deal with. Thank you for the perspective as always. Coming up next, the search for flight 370 expanding now below the oceans surface. Locators trying to detect the planes black box are now in the water, but are they even close to where the missing jetliner went down. We dont know what she looks like. Army officials wont even release her name. Who is the woman being called a hero for doing what she did during the ft. Hood shooting. [ female announcer ] you get sick, you cant breathe through your nose. Suddenly youre a mouthbreather. Well, put on a breathe right strip and instantly open your nose up to 38 more than cold medicines alone. So you can breathe and sleep. Shut your mouth and sleep right. Breathe right. Welcome back to new day. On this friday. Its half past the hour. Lets take a look at your headlines now. The underwater phase for the search for flight 370 is now underway. Theyre hopeing to detect a signal from the missing jetliners black box. As a reminder, it has been 28 days since it vanished. Authorities are focusing on the Mental Health of the man who opened fire at ft. Hood. Lopez may have also had an argument with someone before the shooting. Security procedures are coming into question now after the bases second shooting in just five years. Search crews have pulled another body from the devastation in washington state. The death toll is now 30. 17 people are still missing. Authorities say the debris is some 70feet thick in some places. They say the slide was moving around 60 miles an hour when it hit the area. A major decision from the fda. Regulators approved a handheld injector containing a drug that reverses the effect of hair win. Its kind of like the epi pen used to treat allergy attacks. Quite an innovation. Kate, over to you. Lets get back to the underwater search for flight 370s black box. Joining us for a closer look, jeff wise, cnn analyst. I want to talk about the fact that we not only continue the search from the air, but also now from the surface. Its important to remind our viewers, the questions always asked, why cant they just find it. Heres one reason. Lets just lay out how vast the indian ocean is. You can fit both the United States and china in the indian ocean. This is an area where clearly the radar is not tracked. So with all of that in mind, what what talk to me abo
