about a possible link to one of the boston marathon bombing suspects. one month from today at the boon marathon, 100 runners will make up team mr 8, in memory of martin richard the youngest bombing victim. his sister was injured in the attack. the family released this photo today showing jane with her new prosthetic cheetah running leg. certainly a brave little girl. >> susan, thanks very much. that does it for us. we'll see you again 11:00 p.m. eastern tonight. "piers morgan live" starts now. this is "piers morgan live" and i am bill weir filling in tonight. as search planes zoom over that lonely water of the indian ocean, spending hours searching for what could be an 80-foot floating piece of this puzzle, we're going to look into two possible fresh leads. we'll see if there's anything to glean from transcripts of radio conversations between the flight

370 cockpit and the control tower in kuala lumpur. and then there's the revelation by malaysia airlines that there were potentially flammable lithium batteries in the cargo after all. cnn reported this a week ago, then four days ago the airlines ceo denied this report, instead said there was nothing more dangerous than mango steamed fruit in the cargo hold. today that story changed yet again. we've been looking into the potentially flammable volatility of this kind of battery, the sort used in laptops and cell phones, the sort that in the right kind of conditions can really go up in flames. but wouldn't the state-of-the-art fire suppression system on a 777 stop a blaze like this? we'll talk to our aviation experts tonight. and two weeks into this mystery we'll give you the latest on the search as a growing coalition of nations puts aside their politics for the moment and teams together for this extraordinary hunt. they're using everything they've got. high tech aircraft, huge vessels, sonar, radar, right down to old-fashioned eyeballs

through the binoculars there. but the search area, and that dark corner of the indian ocean, so huge, so remote, they can only cover a few small sections at a time. and with bad weather on the horizon, this round the clock hunt is only bound to get tougher. and as our week winds down, oh, do i have a story for you. the kind that will put a lump in your throat in the best possible way. for over 40 years he was denied the highest honor in the land because of the color of his skin. but that changed this week. and thanks to our great new animators here at cnn we're going to make sure his story is not denied again. but our big story once again tonight begins down under with kyung lah in perth. good to see you once again. how goes the search tonight? >> reporter: well, we can wrap it up in basically one word. more. there are more planes heading down to that area throughout the day. there are four already in the air here. this is saiturday. they are not taking the day off. the military in australia

getting more countries involved in this, hoping to get even more planes in. a total of six heading down to this remote area. the interesting thing here, bill, they're using these civilian planes. the planes you might see in a movie that the rich guy flies. those planes can get down there very quickly. they're using human spotters. they don't have radar. and they're going to scour the area using eyeballs and then jet back. so they're using a combination of things. military prop planes with radar and then these civilian planes with trained eyeballs, bill? >> that's an interesting development. get those fast jets in and out of there. i want to play a little bit of prime minister -- australia's prime minister tony abbott after the last search. and his remarks seem tempered. take a listen. >> it could just be a container that's fallen off a ship. we just don't know. but we owe it to the families and the friends and the loved ones of the almost 240 people on flight mh 370 to do everything we can to try to resolve what is

as yet an extraordinary riddle that's about the most inaccessible spot that you could imagine on the face of the earth. but if there is anything down there, we will find it. >> they tried to temper things a couple days ago but there was so much excitement that something, some possible clue was found out there. but i wonder if the morale is starting to dip. what are you hearing about the energy level of the search crews after this time of fruitless hunting. >> reporter: yes. it really does depend on who you speak to, bill. because when we saw the new zealand search crew come back, they seemed to be quite deflated. they were very disappointed they didn't find anything. certainly the australians seem disappointed as well. but what you heard is that they had hope. they feel that this is a good lead, that they want to get back into the air, that they want to scour that area. and underlining everyone, even though they may be disappointed, we're now in day three here,

they want to get answers to these families. hundreds of people who are around the world, bill. >> and how's the forecast? weather forecast for this weekend? >> the weather forecast is not bad. this is an area of the world, we should point out, that is remote, it is tough conditions normally. the waves are extremely high. but what we hear from the search teams is that the conditions yesterday were quite good. only five to ten feet as far as waves. remember there's no land around there so you get extraordinary high waves. they felt it was pretty good yesterday. they're expecting good conditions today. >> kyung lah, as always we appreciate your reports from down there. more breaking news back stateside, britain's telegraph reporting it has a transcript of 54 minutes of communication between the cockpit and air traffic control of the plane's last messages. we knew about all right good night. this is the first time we've had an indication of what the conversation was before this. meanwhile american investigators

are also learning that files were deleted from the pilot's computer even closer to the flight date than they originally thought. that could be meaningful or not. we all clean off our computers from time to time. cnn's pamela brown joins us now with more on this. let's start with the "telegraph" reporting on the transcript. a few caveats, right? >> reporter: that's right. at first glance it looks uneventful. but there are parts of this purported transcript that the telegraph newspaper obtained that could be interesting to some, especially considering we're dealing with a missing plane. and there are a couple of aspects of it. for one the pilot repeated the altitude of the plane. and also at the very end of the 54-minute conversation the pilot didn't repeat what air traffic control said. now, that's a standard operating procedure. the pilot is supposed to repeat it. that doesn't always happen according to pilots that we've been speaking to. it's not uncommon for pilots to use sort of informal conversation with air traffic

control. but everything is being picked apart here and being scrutinized because of the fact this plane is missing. but important to also note here that this transcript was translated from english into another language and then back into english. so some of it could have been lost in translation, if you will. and also cnn has not been able to verify the authenticity of this transcript and also the newspaper, the telegraph newspaper says it reached out to the office of the malaysian prime minister and the office said thought would not release a copy of this transcript. >> right. i think it was mandarin chinese. so obviously some nuances in that conversation could be lost in there. but it was revealed that the captain placed a cell phone call from the cockpit. we all call home waiting to take off. anything being made of that? >> reporter: well, at this point it's not being looked at as a smoking gun here. from the very beginning of this investigation they were looking at the phone records from the pilots and the passengers.

so at this point there was a report out the malaysian officials acknowledged this morning essentially this pilot may have made a phone call in the cockpit. of course they're going to look at that because we don't have any answers right now. also the deleted files on the hard drive from the pilot. we're finding out from sources who talked with my colleague evan perez some of the files were deleted more recently than originally disclosed by malaysian officials. so forensics experts and outside consults are working right now to find out what is in those deleted files but how they were deleted. that could be very telling if they were strategically deleted or scrubbed clean in a more sophisticated way than a routine way. on the other hand it could be very innocent, just routine deletions like something we would do on our computers and phones. >> if anything it tellsout fbi is finding things the malaysians could not. so maybe we'll get more thorough answers. pamela brown, appreciate that. an international flotilla

headed to the search site right now as we mentioned. ships from australia and china and malaysia and the u.k. but as we told you last night here, the first ship on the scene is that big one from norway. a massive cargo ship that rerouted. haakam svene, thanks for dialling us up again tonight. so how many times have you talked to the crew aboard that ship and how are they faring? >> well, thank you for having me. we're in more or less regular touch with the crew on board through the ship phoning company here in oslo. and what we have from them is that they will continue searching for their fourth day in the area for whatever the

australian rescue coordination center would like them to search for. so they will stay on through saturday for as long as they are needed. >> right. how much sea have they covered so far, do you know? >> well, today the plan by the rescue center in australia is that the nnorwegian ship which cover an area approximately 90 miles long. now in this part of the indian ocean they're already working to cover that area. it's sort of a sector which is approximately 90 miles long. they'll move through that sector in a particular pattern. they will of course keep in constant touch with the australian authorities leading the rescue effort -- search effort, for any changes to that plan. >> haakam, i failed to ask you

this last night. this is a car carrier. 7800 cars potentially on that thing right there. it's not a search and rescue vessel by any stretch. but if you do find the piece everyone is looking for, is there a way for you to retrieve it? are there divers? any diving capability on that ship? >> there is no diving capability. but the most important asset on that vessel is of course the eyes and the binoculars of the crew. and a big part of the 19-strong crew is now actively engaged in searching the area. this is something a crew on board any merchant vessel will be able to do. these guys have shown over the past several days they're able to search through areas at the direction of the australians quite well. this vessel has a free board of some 80 feet. so it's a pretty good observation platform for

whatever is in the immediate area of the vessel. and they're under constant direction from the australians for where to look for what. >> you've got a norwegian ship, mostly filipino crew, part of the international search on that high high boat there. thank you, we appreciate your time. with planes and ships all converging in that area, attention turning to exactly how they'll look for a trace of the missing plane and white caps and tides and winds, and one answer might be satellite tracked buoys that can help. we'll get a live demonstration here tonight. luka, great to be with you. show us what you're doing. these are satellite buoys? how do they work? >> right. so what we have here is what we call a drifter. and this instrument is designed to do basically three things. we have an element which is

underwater. we call it a drug. that follows the ocean currents. then we have another sensor which is a temperature sensor. it measures the temperature of the water. then very importantly we have another sensor which is atmospheric pressure sensor. and what we do we feed all the data real time to anyone who can make use of it. so all the operation agencies that can do weather forecasts are able to use our data. >> let's see this thing in actio action. >> so here how we can deploy, it's very easy. they can be either from the airplane or one person can deploy it from the ship. basically you just throw it overboard and the drifter starts the mission automatically. here it goes. >> and this is going to be pivotal. this kind of device in helping crews figure out drift patterns,

so if they do find any debris from flight 370 it will help us out. we'll check back with you, luca. we appreciate your live experiment with us. when we come back, more on that transcript. 54 minutes of messages from the cockpit. are there any clues? we'll dig in next. [ coughs, sneezes ] i have a big meeting when we land, but i am so stuffed up, i can't rest.

once again an international force of search planes is headed for that site in the southern indian ocean at this very moment. we'll update you on that when we get word. we told you about the transcript of the last 54 minutes between flight 370 and air traffic controllers in kuala lumpur. joining me now, mary schiavo, former inspector general at the department of transportation. she represents victims of accidents. also cnn's richard quest and david soucie, author of "why planes crash." good to be with you again.

richard, it seems rather pro form m forma. what do you see here? >> there are some sloppy read backs. all right good night without a full proper read back. there are some -- he's repeated things once or twice. and indeed the translation is really i have poor. because for example, at the takeoff the air traffic control just said runway ready permitted to take off. there's no wind speed, there's no wind direction, anything you would expect to see in this. it's a poor translation. it tells us -- my own view is it tells us nothing new. >> we should slather this with caveats. the telegraph tried to get confirmation from the malaysian government. they wouldn't give it. it is an english translation from a mandarin translation as well. but mary schiavo, what about the repeated altitude that there was no need for him to say twice that he was at 35,000 feet? >> well, there was no need for

him to say it but it's kind of pro forma like what richard said but also just communicating where he was and giving positional information. i read absolutely nothing into it. and the informality of the comments about good night, i went back and read through the transcript and noticed that air traffic control twice before the pilot said good night had given the plane instructions and they had said good night. so they were just responding in kind. >> and david, are you surprised that they won't release this officially at this point in the investigation? >> i don't think so. i don't think there's anything suspect in that at all. after thousands of hours of riding in the cockpit observing pilots, it's typical conversation other than the translation errors that richard pointed out. >> you've got some guys who are probably letter of the law. >> absolutely. >> even a faa inspector over his back it gets casual. >> i'm going to argue against myself having said this. >> please do.

>> this just shows the nature of this whole story. anything that i think you might raise an eyebrow is what's not there. if there was a fire, if there was an incident, if there was something happening mechanical in between when the acars switch stopped transmitting at 1:07 and we got the good night at 1:19 you'd expect it to be in the transcript. it's not there. so if by elimination and deduction of the negative we could perhaps say we can take something out of it. >> well, whatever theory you come up with in this whole thing, there's a hole in it. there's a massive hole in it. so if you change the flight direction 12 minutes, if that report is accurate before saying good night, it just doesn't add up. >> but that's typical of every investigation. everything i've always been in. if there's an accident it's not one thing that causes that accident. it's a plethora of things. and it's not just narrowing down

one thing saying yes, it is no it's not. it can be combinations. things that are unimaginable, combinations that are unimaginable looking at the complexity of this aircraft. it really becomes extremely difficult when you take one piece of evidence by itself. it really has to be a culmination of each piece of evidence and then weighed against each other. >> right. mary, day 15, still nothing. at what point do they move this search out of that area of the indian ocean? >> well, i don't think they'll do that yet because the satellite company in marsat said today that they had given these coordinates to the authorities two days after the accident. so if they have some sort of a location and they've stated that they do, i think that they will look in that area. not for floating pieces of wreckage but perhaps under the surface of the water on the ocean floor for the black boxes or for other pieces. now, i was a little surprised at that announcement today. but that would give them another

place to look except not on top of the water but underneath. >> and the u.s. military we just learned today has spent $2.5 million so far op on this search and rescue. they have budgeted about 4 million. have we ever seen a situation where they just stop looking? they run out of money and interest? >> they don't stop looking. and they certainly don't stop looking for want of money. what they do is, they redefine the search parameters. air france 447, they found the original debris, they knew roughly where the plane was. but they went back three or four times. but each time had to be a much grander operation, underwater submersibles. so no, i don't know whether you would disagree. >> yeah. the reason that happened on 447 is because the basian theory had been modified. there was new information. they assumed that the black box pinger was on but it wasn't. they had both malfunctioned. so they had to go back and

re-search with a different mentality. once they adjusted their model they found it. >> hang out with me, everybody. when we come back i want to talk about the other big question. were lithium batteries in the hold cause for alarm in that disappearance of 370? also we're going to check back in with our sonar buoy live demonstration. please stay with us. no matter how busy your morning you can always do something better for yourself. and better is so easy with benefiber. fiber that's taste-free, grit-free and dissolves completely. so you can feel free to add it to anything. and feel better about doing it. better it with benefiber.

back to our news tonight. those military and civilian planes -- civilian planes now joining the search in the southern indian ocean looking for any trace of flight 370. also tonight the ceo of malaysia airlines said the plane was carrying a shipment of lithium ion batteries. although he didn't say how large that shipment was, it doesn't happen often but these batteries have been known to explode. so is that a possible cause for concern? back with me mary schiavo, richard quest, david soucie. so since 1991, there's a list that the faa has here. 23 years. only 141 incidents. and we know there was a big ups plane that went down as a result of this. but richard, most of these are trivial. >> not only are they trivial, they didn't even happen on the plane. most of them are either in the sorting area, the presorting, being loaded on to the plane, and they all really concern fairly substantial numbers of lithium ion batteries.

usually for one of the major companies the upss or the fed-exs. the number of occasions where for example in 2011, delta airlines passenger's device became very hot and the plastic started to melt. but the number of those sort of incidents are really quite small. >> and if it was to burst into flames, let's say even a pallet of lithium batteries to explode. this is a state-of-the-art fire sues premise te suppression sys? >> the interesting thing about lithium they have the capability of reigniting. so even though that happens, as soon as it restabilizes it could reignite. and there's not a second charge that would go off in there necessarily. there is in some compartments. >> mary, let's say that happened. how would the pilots know? wouldn't somebody on the ground

know that this was going terribly wrong? >> well, there is a smoke and fire detection and suppression systems in the cargo holds of these wide-bodied planes. however, we know about this. and what happens and how it reignites and how difficult it is to put out because of the boeing 787 fires in boston and in japan. and the firefighters themselves reported that they kept trying to put it out and it would keep coming back. it was very very stubborn. and so that's why boeing reinvented the box on those planes. remember those planes are being used so they're drawing current, there was grounding issues, et cetera. so boeing redesigned the box. and the box is supposed to contain any kind of a battery fire. so it was very stubborn to put out. >> help me remember, what was the swissair flight where he went out to try to dump fuel over the ocean? >> that was the ife, in-flight entertainment system from new york to switzerland, to geneva.

and that overheated. it caused a fire. it caused a fire which brought smoke into the cockpit. they knew about it. they tried to divert. they tried to get to canada. and they came quite close. but this was as a result of just sheer overwhelming of the smoke. >> and speaking of batteries, 16 days left or so of juice in the black box. does that intensify things for people? or you can only search as fast as you can search in. >> what it does is after that pinger stops, now you've got to search dr -- your area of which you have to search, the grid has to be much less. you have to physically see the box now as opposed to being within a mile or two of the box and to get the pinger. now your grid of scanning and examining the floor has to be much much smaller. >> right. thank you all so much. appreciate your insight and all your work these many hours on cnn. coming up next, reports of the families of flight 370 being forced to leave their hotel in

leading the news again tonight, those military and civilian planes, six of them in total so far streaking toward the remote search area in the indian ocean, hoping to find that piece of flotsam that was spotted from the satellite so

many days ago now. we're going to get word or we'll provide it if we get word. there's also word to be the that the families of the passengers on flight 370, those increasingly desperate and frightened people have been forced to move from their hotel in kuala lumpur. cnn's sara sidner has more. sara, what's happening? >> reporter: you know, bill, these families have been through a living hell. they have been waiting for so long just to find out what happened to their loved ones. still they do not have any more answers about what happened to flight mh 370. and now they have had to move from their hotel where they've been during this investigation to another hotel, about a 20-minute drive away. basically what has happened is, the hotel has been booked up for literally months now because formula one, the grand prix, is coming here. and all the hotels around here have been booked solid for a very long time. and so they didn't have room for

these families. this is particularly the hotel where the bulk of the chinese families have been staying. they had to move from their hotel to a new hotel. and what happens in these cases is that people feel disrespected. they feel they're worried that they're going to be moved away from information. but we do know that there have been representatives there that are keeping them informed. but all in all these families have been saying they still feel like they're not getting enough information. they're not being told information fast enough. and authorities are saying, look, we're trying our best. and we're trying to keep them informed. they did meet with authorities two nights ago to get the very latest information on the investigation. but as you know, bill, the latest on the investigation is that still nothing has been found to indicate where flight mh 370 is. >> those poor people. sara, thank you for that. let's turn to a man who probably knows better than most what sort of anguish those folks are feeling. martin van slyth lost his sister

adrianna on air france flight 447 when it crashed into the atlantic. now almost five years ago we're a couple of months away from the anniversary. martin, thank you for being with us. and i'm sure time is kind that it rubs the edges off the hurt a little bit. but with the anniversary approaching and watching this whole drama unfold, how has that opened these wounds for you? >> yes. [ inaudible ] we were recollecting all the same terrible feelings we had five year ago. so it was [ inaudible ] almost the same story. people hurrying, screaming around, calling cell phones and

pretending to be their family's voices. it happens in some details absolute lit saly the same. and now the families in the hotel, we realized that as well at that moment in rio de janeiro where i was the second day after the crash. >> i understand that you emerged as sort of an organizer, a leader of a lot of the families to try to make certain demands, understand what was happening. tell me about that. does it turn confrontational at a certain point? >> yes, of course. as i told someone of the air france management, we'll never be on the same side of the table. because they have some concerns about the company image and even when they are celebrating our loved ones. i understand they do it in a matter of fact not because of humanitarian reasons but more on

top of that of course because of their own interests. but we grew together after five years. we have a big relationship with french families association, the german families association. and we are struggling until now for the complete disclosure of what really happened with ar 447. it's a long road we'll have to follow from now on. >> right. i know i think they found your sister six, seven days after that crash. i'm sure you were holding out hope all that time. but in this case, two weeks later, what advice would you give to these families in beijing and kuala lumpur, around the world? >> yes. i would give a warm hug to these people and just feel that i'm on the side of them. i understand the anxiety and the

anguish that these hours that seems to be one year long. but there is not much to do. the companies involved cannot give solutions for them. even now they can make big mistakes. so i think they must make a commission of people that represents the whole group of families, at least in china and in malaysia. and then [ inaudible ] representative representativ representatives in order to [ inaudible ] achieve transparency in the communications. and before saying something they don't know, better say nothing for the families. >> martin, we appreciate your time as that anniversary approaches i hope you can focus on the good memories of adrianna. thanks very much. and coming up next we're

going to talk about the difficulty of the search now with two men who have been much experience in the deep waters. they even found a world war ii aircraft carrier. and we'll continue our demonstration of those buoys next.

including inflammation of the pancreas (pancreatitis) which may be fatal. stop taking victoza and call your doctor right away if you have signs of pancreatitis, such as severe pain that will not go away in your abdomen or from your abdomen to your back, with or without vomiting. tell your doctor about all the medicines you take and if you have any medical conditions. taking victoza with a sulfonylurea or insulin may cause low blood sugar. the most common side effects are nausea, diarrhea, and headache. some side effects can lead to dehydration, which may cause kidney problems. if your pill isn't giving you the control you need... ask your doctor about non-insulin victoza. it's covered by most health plans.

how do you search for what may be a trace of flight 370 in the middle of one of the most remote parts of the world? ocean explorers might have the

answer. joining me captain chris curl on board the research ship melville. also joining me is luc luca santorini of the scrips oceanographic institute. captain explain in your experience the difficulty of these waters and a search this size. >> well, the difficulty in general is connected with how objects disperse in the water. so the the more time goes by, the more the objects spread out and the more difficult it is to find them, which is step one. then step two is to track them back to the site of the presumed crash. so we have a great coverage globally. that's the way which is essentially founded by noaa. what we have here, you can see west of australia we have -- the

way we contribute to the operation is bee providing real time data of atmospheric pressure and then ocean currents that can be used to validate the models. >> so that the buoy we saw you drop at the top of the show, is that feeding information back to that computer now? >> it's feeding information in real time to anyone who is capable of assimilating the data. so all the weather centers, all the operational centers, the u.s. navy, australian navy, they all are capable of reading our data and using in their models. >> we'll go into the drift model so you can hopefully narrow the cone of uncertainty. chris, i understand you guys have some experience finding stuff, even off the coast of san diego. it's not all that easy. you found a sunken aircraft carrier? is that right? >> yes. we were involved in the search for the sunken japanese carrier kaga that was involved in the

battle of midway. it was about 1,000 miles north of midway in waters similar to this depth. of course, an aircraft carrier is quite a bit larger than an airplane. and the debris from an airplane would be a lot smaller than looking for an aircraft carrier, which in itself was very difficult. so the task of finding the airplane wreckage is going to be daunting for these searchers. >> i know that chuck hagel, our secretary of defense, is requesting hydrophones, i guess towable underwater listening devices maybe to hear the ping of that box. but for a land lover like me this is probably a dumb question. and my ignorance is obvious in this. why not send submarines down there to listen? >> that's a good question. they are very sophisticated listening arrays. they could probably work for that. that's not my area of expertise,

though. >> yeah. maybe they're down there and they just don't want to tell us that sort of thing. and luca, explain that cone of uncertainty again and how big it might actually be. let's say they find that piece and it is in fact the wing. how big is the search area in something like this? >> well, it depends on what the ocean is doing at that time. the ocean is mainly doing two things. it is moving in a main direction, so direction that the currents are going. the other thing is that because currents are not the same at all locations and there is also wind effect and waves effect obviously will start to dispersement and that will create a cloud of debris this spreading out. and then you have to do two things. first you have to locate something, and then you have to track it back. and every time you do a track back operation, you are going to introduce an error.

because you have to use models that are using data. but there is always some area that propagates and creates some uncertainty that becomes bigger and bigger with time. >> luca, chris, thanks so much for your information here. i appreciate the insight tonight. and we'll be right back with a great story, everybody. don't miss it. on my journey across america, i've learned that when you ask someone in texas if they want "big" savings on car insurance, it's a bit like asking if they want a big hat... ...'scuse me... ...or a big steak... ...or big hair... i think we have our answer. geico. fifteen minutes could save you fifteen percent or more on car insurance. and better is so easy withrning you cabenefiber.o something better for yourself. fiber that's taste-free, grit-free and dissolves completely. so you can feel free to add it to anything.

and feel better about doing it. better it with benefiber. "stubborn love" by the lumineers did you i did. email? so what did you think of the house? did you see the school ratings? oh, you're right. hey babe, i got to go. bye daddy! have a good day at school, ok? ...but what about when my parents visit? ok. i just love this one... and it's next to a park. i love it. i love it too. here's our new house... daddy! you're not just looking for a house.

you're looking for a place for your life to happen.

well, after an intense week after missing plane coverage, i would like to divert for a moment here, finish my fill-in run with something a bit different. it is the story of a brave man passed over. a story that went untold for far too long, and even with all that's going on, we want to make sure his story is not passed over again. this week, president obama awarded the congressional medal of honor to two dozen men who should have gotten this ultimate recognition generations ago but denied because of their race. before the ceremony, i had the honor of visiting one of these men at his florida home. i would like to take you there now and show you what selfless courage really looks like. there's a flag out front, but that's only a small clue on the kind of man who lives here. there are military honors on the walls inside, but framed paper can't really do this man justice. and he's loved by a beautiful family. but even they don't fully know

the things he's seen. did you grow up knowing your dad -- or your grandfather was a war hero? >> that is a tough question. until today i didn't know the entire story. >> his name is melvin morris. the army didn't have to draft this kid from oklahoma to vietnam. he signed up. >> we seen a few guys around. they looked good in their uniforms. >> when he heard the army was creating a new kind of special force, he signed up. >> the word around is they were snake eaters and sneaky peek. >> and you wanted some of that? >> i wanted that. >> and these were the green berets? >> right. >> barely out of his teens, melvin saw a lot of action, dodged a lot of bullets but nothing like the morning he walked into a village in september of '69. >> i'll never forget, she was

cooking outside and my stomach was in knots. that was a bad sign. >> minutes later, his captain was shot and his team sergeant killed. he had no choice. he had to wade into that fight to get the body of his friend. >> i gave him last rites and two with me got wounded. i had to take them out. while they were dragging the body out, the map case fell out of his pocket. all the hand grenades i could get my hands on and i started growing grenades. i get the map case and while i'm doing this, one of the enemy come up to the right. he shot me. i hate to say it, but i shot him.

i don't like to talk about that. i got up behind a tree and i started throwing hand grenades. i seen him flop. i'm going until these details are coming back. they were trying to take the tree down. they couldn't come to me, over me, but they had to find a way to get rid of me, because i was fighting back. so bullets were hitting the back of the palm tree. evidently they decided to give me a break because they went silent for a second, and i started running. i ran a quarter mile, maybe a little better. what i had told my sister, if i go down, don't come get me. we can't afford to have anybody else killed. >> as you're pinned down behind that palm tree, are you thinking about your beautiful wife, are you kicking yourself? >> no, i'm not thinking about

nothing but how do i get rid of the joker that's trying to kill me, and how do i get out of here? >> wow. >> i said, what would john wayne do? >> 27-year-old staff sergeant morris. >> after investigation, the pentagon decided that morris deserved the highest honor in the land but never got it because he is black. but he said racism is never something he thought a lot about. >> in the green berets, you got awarded for what you did, i don't care what color you are. maybe some injustice can be corrected and we're on the right track now. so it's all okay with me. >> i think it's interesting, and i want to respect your boundaries, but you say the hardest part to talk about is when you shot the enemy that was trying to kill you. why?

>> i'm sorry. i'm sorry. well, my wife will tell you, i never speak about killing. i don't. i was involved in a lot of combat, but i feel like when you take a man's life, you own it. i own those souls. so i don't talk about -- i don't brag about that, i don't talk about that. it's just sacred ground. i don't go there. >> what was it like coming back when the war was over and you were back state side, did you still carry those wounds inside? >> i carried them for a long time. to be honest with you, i had a difficult time. i suffered from post traumatic stress. >> still? >> still today, yeah. >> you were telling me that going to throw out the first pitch at the washington

nationals spring training game was a big deal because you were never comfortable around crowds. >> exactly. normally being around crowds, i had a little help. i wasn't in control until i went to the v.a. and just turned myself in. >> did they help you? >> oh, yeah. that's why i'm silent right now. they've got a lot of soldiers that need help with this ptsd. and i know if it can work for me it can work for the rest of them. >> i'm just struck looking at this picture of you, this bright eyed kid from oklahoma, the whole world ahead of him. knowing what you know now, would you do it all over again? >> i don't regret not one minute. if they told me i could go back in the military today, they need

me, i would go. at my age. >> it's an honor to meet you, sir. thank you for your service. >> all right. >> thanks to my new friends at the cnn digital studio. the latest on flight 370 with don lemon starts now. >> good evening, everyone. this is a cnn special report. the mystery of flight 370. i'm don lemon. we have breaking news for you tonight. planes are in the air right now, searching the southern indian ocean for traces of flight 370. britain's telegraph is reporting it has a transcript of 54 minutes of communication between the cockpit and air traffic control. and u.s. investigators say so far, they see absolutely no sign of a terror plot. their leading theory is the whole thing was a tragic accident. but they can rule nothing out. there
