remember, the bluefin-21 comes up tomorrow. they are hoping to get that information back from the bluefin. let's hope it is working properly this time so it can stay down the entire 12 hours. that's it for us tonight. i'm don lemon. "ac 360" starts right now. good evening, i'll bill weir. >> breaking news a sonar sub in the water water and the search is back on track. tonight you will see what a bluefin-21 can see down there in the side-scanning sonar. also breaking what appears to be the largest, most dangerous gathering of al qaeda in years fe question did the pentagon know about it or not and dr. sanjay gupta is fighting to stop the ebola crisis. some medical personnel have lost their lives in the battle. we have the latest from nearly

three miles deep where bluefin sonar scanner is deep in the water, deep in who what is expected to be the first day on the job. as you know yesterday's mission was aborted after six hours. today's dive is expected to go around the clock. there are new developments on that front, new developments, as well, with that oily substance recovered from the ocean surface and a tracking system for planes that's being rolled out over the next six years that may have changed everything that happened to flight 370. the question is why six years from now will it be rolled out? what is taking so long. first michael holmes in perth on today's efforts. what's the latest, michael. >> reporter: anderson, good morning if from perth. the bluefin-21 down doing its work at the moment. by our calculations it is almost half way through the ocean floor segment of that as we know it takes two hours to get down and 16 hours on the bottom and two hours to get up and then they download the data. planes and ships out there

today. we had been told that phase of things looking for surface wreckage would be scaled down this week. no sign of that yet. they are still in the air and on the ocean looking for any wreckage. of course, none found so far. we're now in to our sixth week. >> none found so far. the data, has it been processed from the bluefin's first dive which was called off because of unexpected depth that it suddenly faced. did they find anything of note? >> good question. in fact, only in the last hour, anderson, we did get word about that. it covered about four square miles during that aborted mission. on a normal mission, it would cover 15 1/2 square miles or 40 square kilometers. they did analyze the data and sad to say they found absolutely nothing of any use, nothing relevant. of course it was just the first mission and an aborted one at that and this is a huge area they are covering.

anderson? >> the fuel recovered from the search, is it related to the plane? have they been able to determine that yet? >> not yet, no. we have to remember, that search area is about 2,000 kilometers off the coast of western australia. they did pick up the two liters of oil they found floating out there near where the ocean shield is. they bottled that. what they have to do is get a ship out there and then helicopter it to that ship. the ship can get it closer in and then the helicopter will take off again to get it here to perth. they said it would take two or three days. in a day or so, we will know what that is. they have sent samples actually of the engine oil that would have been in mh-370's engines so they can do a comparative analysis on that. they are also going to check to see if it could be hydraulic fluid, as well. still unanswered questions. even getting that back here is a bit of a journey, anderson. >> appreciate the update. i want to bring in the panel,

cnn safety analyst, david soucie, author of why planes crash. and director special project the oceanographic institution and mary schavio who currently represents accident victims and their families. david gallo, the fact they didn't get data from the bluefin, i don't think you would be that surprised. >> they got data, just they didn't see anything -- this is all typical of the first days of an expedition like this. it's unfortunate and frustrating, especially but it is ott unusual. >> the mission was aborted because of the depth they found themselves in deeper water than anticipated. the surface wasn't that deep and had to call it back and recalibrate things. is that going to happen more and more. does that indicate a lack of understanding of what the depth is? >> every day they go out there

they are going to learn something new about the terrain and will make adjustments to the hardware, software, the vehicle and operations plan. it may happen once or twice more. in the air france 447 we had a lot of aborted runs from our robots but you learn. the team is capable so they will learn. >> why not have more than one bluefin. air france had three vehicles. >> i think their approach is different. they are going, captain matthews talked about the tactical approach. they have a solid pinger location and will throw the dart at the bull's eye. our idea was to pick an area that's much larger than the search area and do the entire area, coffer it with multiple vehicles. a different mapping program. >> david, do you think that indicates perhaps they have more information than they are letting on? >> that's the way i'm seeing it. apparently they have a lot of confident dmens where it is or they would have more, like david

gallo said, more to throw at the target instead of a mass screening of the area. it does indicate that to me. >> the navy has said they do, david, have another underwater vehicle that can go deeper. >> they have plenty of tools in the quiver they can bring to bear in this. if they need to change strategy, maybe this tactical means is not working they will bring something else in on the mission. >> mary, we heard from the air marshal, angus houston, the air search is nearing its end. that's not is something the families want to hear. >> well, that's true. at some point, the currents have now worked their will on any debris that might have been on the surface for, five, almost six weeks. there's just not a real chance they are going to find much at this point, this far out, it would be so far dissipated and can't justify it. particularly if, as the other

guests have said, they really believe they have zeroed in on the point where the plane is. there is of course always the many stories that float around about australia's incredible radar, almost mythical qualities, i guess. perhaps they have additional information but they are throwing the dart at the dart board right where they think the bull's eye is. >> it is amazing a plane theoretically can hit the water and no debris be found. i guess there was the ship the sydney which went down and only a life raft was found. >> i believe it was years later on christmas island, thousands of miles north of the site one life raft showed up. >> incredible. >> absolutely inkredable. >> we heard the malaysian transportation minister say it matters less who takes control of the black boxes as long as the black boxes are found. to you does it matter who takes control? >> that was disturbing to me to hear that. it really doesn't matter who takes control. it matters a great deal and he's in charge of the investigation.

by rules, nothing goes anywhere until he says. he is responsible for the decision. if anybody i would think he cares. >> we heard them say they are setting up a committee to look in to how a plane could have vanished without hardly a trace. is that what should be happening at this point? >> well, that plus more. when we do an investigation, when the ntsb does an investigation, they set up similar committees except far more. good they are setting up committees to investigate but the true investigative committee that should be working overall to solve this accident, the causes, the probable causes, any recommendations, the full, should contain far more working groups and committees. if they are going to be objective and look at how this happened and look at their own response or lack thereof it is good they do that. >> and multiple fronts to work on. a lot to cover including

underwater territory no one has seen before and putin's assessment to pave the way for russian tanks. let us know what you think. coming up next, david gallo shows amazing look at what the ocean floor looks like, two underwater sonar devices, the bluefin-21. markab ma remarkable pictures these things can take. >> may day, going down. >> we will show you what begins as a disaster becomes an opportunity. air crashes over the years that have made air crashes today so rare. lessons learned and what is being learned this time when we continue. ameriprise asked people a simple question: in retirement, will you outlive your money? uhhh.

no, that can't happen. that's the thing, you don't know how long it has to last. everyone has retirement questions. so ameriprise created the exclusive.. confident retirement approach. now you and your ameripise advisor can get the real answers you need. well, knowing gives you confidence. start building your confident retirement today.

with the bluefin back underwater search teams will get

a better chance of finding flight 370 and a better look at the lay of the land on the ocean floor, the nooks, crannies, hills and mountains down there. back with me now is david gallo. we have a sonar image. this is clearly two ships. what are the different colors, different depths. >> the more i look at this, you are looking at different depths and looks like the blue is shallowest. this looks like a mast here. >> this would be a mast here. >> right. this is the image that bluefin can take of objects on this sea floor remarkable to see it like this. can you get this in one pass? or does it need multiple passes. >> it depends how close the vehicle is to the bottom or how high and big the area is but it could be one pass or multiple passes. >> i want to look at an image from a side-scanning sonar. this is a close up of one ship.

>> this is fantastic. this is the path of the vehicle. the robot is heading in this direction, sending out pings to either side. the side comes and bounces off objects. it is a hard return. a shadow behind it. this is a ship sitting on the bottom and you can see it went over the top of the ship. it leaves a gap beneath the vehicle. why they call it a side scan or side-looking sonar. >> when you get an image like this it is actually two images with the center. >> it is two beams on either side of the vehicle. exactly. port side and starboard side. >> it is not from a plu fin but on a search you were involved. this is actually the "titanic." >> "titanic" split in two. looking at a mile across. these lines here are the path of our vehicles, back and forth, mowing the lawn or plowing. >> i see. you can actually see lines in the image itself. >> exactly right. that is many images. that's a mile across.

that's the bow of the "titanic" here. it broke in half. this is the stern of the "titanic." six football fields away. all of this is a debris field. this is the kind of thing when you look at an aircraft on the bottom, all of these things are everything from pieces of pottery and lights. >> all of this. >> all of these speckles and bigger pieces inside of here. >> so the "titanic" had a wide debris field. >> stern especially. the bow not so much. the "titanic" had a huge debris field associated with it. >> zooming in on the bow. it shows how powerful sonar can be. >> incredible. >> this is one pass along the bow and this is the pointy end where jack was the king of the world, the mast, the openings here. >> you can get this from one pass. >> one pass, yep. and sometimes we go over it two or three times to make sure we don't miss anything. >> what vehicle took this.

>> the rema 6,000. it is similar to the type of vehicle the bluefin is. >> it is made for deeper water work. >> incredible. one other image of "titanic" again. this is extraordinary. >> this is actually an optical image. many many. you can see the size of one image. >> this is multiple photographs. >> this is done with a me remora which is separated by phoenix international that may or may not come in to play in the malaysian air search. this is the optical view of the same bow. >> that's an underwater vehicle that takes under water images. >> it goes alongside the ship click click, anyone who has done a panoramic view knows how hard it can be to get it right. it's not easy but there it is. >> incredible. the technology. thank you so much. for all the bluefin-21 can learn

it's only there to take sonar pictures. the next step is to send down other submersibles that can do more. gary tuchman got an upclose look at one vehicle that played a key role in finding pieces of space shuttle "challenger." here's what he saw. >> reporter: at first glance it reis semables a spacecraft more than anything else but this is a research sub that has combed the seas doing everything from medical research to ship and aircraft recovery. >> we have an array of light systems on the sub. so you can turn on whichever light you need. >> reporter: jimmy nelson used to spend 170 days a year on the sub. the johnson seaing submersible. >> ready to go. >> ready to go. >> but other manned sea vehicles maybe next to line to aid in the malaysia airlines search. >> if this or another submersible can get where the wreckage is, how effect i have do you think at this time could

be? >> very effective. >> reporter: this is the view of the submersible in the atlantic ocean. it can go 3,000 feet deep. like all research subs it's slow. only travels just one mile an hour when searching. the sub was called to duty in 1986 after the space shuttle "challenger" exploded. and it recovered some of the wreckage from the ill-fated shuttle. >> we have the capability of lifting 1,000 pounds of weight to the surface. >> reporter: the front of the submersible, a tool called the manipulator that grabs, scoops and sucks up samples that are recovered. this sub is 24-feet long. it is also 11-feet tall and weighs about 28,000 pounds. it has enough oxygen and emergency provisions on board for the people to survive underwater for up to five days. there's also a bat cabin called the aft observation chamber.

a crew member who keeps an eye on the vital signs and soot scientist share the back area, which is only 5 1/2 by 3 feet. >> so, just to give our viewers an idea how tight it is, this is how you are sitting. this is how i'm sitting and you can be here for hours. >> reporter: but during those hours this is what is taking place. >> so we fire up the sonar system. it does a sweep and paints us a picture as it spins 360 degrees. if there are solid targets on the bottom it will beep and paint a small picture of what it looks like and we can motor that way. >> the use of high-tech underwater manned vehicles is increasing but he says manned submersibles offer important dimension. >> sometimes having human being can spot things unmanned cannot spot. >> correct. >> others could be snent to action underwater in an effort

to solve a mystery. gary tuchman, cnn, fort pierce, florida. >> incredible technology. for more on the story and others go to cnn.com. coming up, could a new system for tracking planes with gps and satellites prevent this type of situation from happening again? the question is if so why isn't it implemented right now? also, life-saving lessons from dangerous crashes over the years. and later tonight, breaking news, a cnn exclusive a new al qaeda video is surfacing. a top leader meeting with more than 100 followers. we will tell you why it is so important. and the question is did the u.s. know about the meeting? [ male announcer ] this is joe woods' first day of work.

and his new boss told him two things -- cook what you love, and save your money. joe doesn't know it yet, but he'll work his way up from busser to waiter to chef before opening a restaurant specializing in fish and game from the great northwest. he'll start investing early, he'll find some good people to help guide him, and he'll set money aside from his first day of work to his last, which isn't rocket science. it's just common sense. from td ameritrade. it's just common sense. predibut, manufacturings a prettin the united states do. means advanced technology. we learned that technology allows us to be craft oriented. no one's losing their job. there's no beer robot that has suddenly chased them out.

the technology is actually creating new jobs. siemens designed and built the right tools and resources to get the job done.

the crash of flight 370 and the mystery surrounding it understandably scares everybody. the fact is, though, your drive to the airport is many, many more times dangerous than the flight. and there is a reason for that. the business of making planes, and carrying passengers, and the regularinglation of the industry is very much a tight knit community with a long tradition of learning from past mistakes, or like this anticipating them. it is requiring all aircraft operations in the u.s. be ready for it with the right transmitting equipment by 2020. it's the sort of system that could have made following 370 so much easier and like many innovations it evolved from bitter lessons learned the hard way. randi kaye reports.

>> reporter: valujet flight 592 from miami to atlanta, the day before mother's day 1996, the pilots hear a loud boom six minutes in to the flight. >> return to miami. >> what kind of problem? >> smoke in the cabin. >> the pilots head to the nearest airport. meanwhile, passengers are yelling about a fire. the aircraft rolls on its side and then crashes nose nose first in to the florida everglades killing all 110 people on board. the ntsb determined the fire began in a cargo compartment. >> if we have fire detection system the crew would have been afforded more time to get the plane on the ground. >> reporter: the faa took those words to heart and as a result revised standards for cargo requiring smoke detectors and automatic fire extinguishers in cargo holds. >> we are on a mayday. we're going down.

>> reporter: fire was also a problem in 1983 when care canada flight 797 made an emergency landing at cincinnati's airport on the way from dallas to the toronto. it had a fire in the bathroom. >> we have a fire in the back washroom. we're filling up with smoke right now. >> reporter: incredibly the plane landed safely but half of the passengers and crew died because they couldn't exit the plane fast enough. that gave rise to new fire safety standards, including bathroom smoke detectors and automatic fire extinguishers. today planes are much more fire resistant. carpets and seat cushions are made of a material that burns slower. passengers can get out faster, thanks to new, improved exit doors and those floor lights that the flight attendants point to every time before takeoff, those were added to save your life, too. smoke in the cockpit was the problem on swissair flight 111

after it took off. >> we have to land immediate. >> it crashed just off the coast of nova scotia killing all 229 people on board. investigators traced the fire back to the plane's entertainment system and mie lar insulation. following that crash, the faa ordered all mylar replaced with fire resistant material. >> we have called for a review of in-flight firefighting standarders in the industry. >> reporter: in 1985, we saw a huge improvement in technology to protect us from high winds after delta flight 191 crashed at dallas-ft. worth international airport. it was landing during a thunderstorm. 137 people died. after much research by nasa and the faa, forward-looking radar wind sheer detectors became the standard.

the crash of twa flight 800 just after takeoff from jfk airport in 1996, was another hard lesson. >> two fire balls go down to the water. >> the ntsb determined an explosion in the fuel tank caused the crash, blaming it on a wire that short circuited. the faa later mandated changes to reduce sparks from faulty wiring. randi kaye, cnn, new york. >> joining me is safety analyst david soucie, author of whys plane crash and les abend. does it seem like change only occurs in the wake of a tragedy, or is the industry proactive? >> i think dave will agree with me this is what we call tombstone technology. >> tombstone technology. >> yeah. when something tragic happens, these changes occur. it's traditional for the ntsb to and the faa to be at odds.

one is a regulatory agency and one finds probable cause and says we recommend this. dave has probably been at the forefront of this. >> you agree with tombstone -- i have never heard that term. >> it is what the faa has been working away from a certification process. as a result of the fact that now it is not just a singular cause and having it fixed. it is more complicated. as the aircraft get more complex you have to look at the relationship between the systems and look for precursors. >> with this gps system that they are going to have in place by 2020 in the united states, would that have made it much easier? if it was on -- in the area for flight 3 flight 370 to track it? >> yes. >> yes, absolutely. the certification process said we need to change how we do

things, including the air traffic control system. the next process that came out, they would have information constantly about every other aircraft that may even cross their path. >> would it still be possible, les, if a pilot or a co-pilot were able to make a plane go missing, would it still be possible to do that, to make a plane go missing? >> well, dave and i talked about this new system, the satellite-based system. the airplane regulates the system, they send it to a satellite system, the ground system sends it to air traffic control. this is what i use in the north atlantic. it is mandated almost totally in the north atlantic at this point and also europe. could it be turned off? you are turning off the flight management computer. dave and i discussed the technology that the transponder doesn't have an effect on it. i have to verify that. but to the best of my knowledge at least on the triple 7 you have to turn off the flight management computer in order to disable that system.

>> you agree with that? >> yeah, i do, the point of this system is that it can't be turned off. the beauty of it, is everybody is interlaced and everybody knows where everybody is. if anyone goes off the system it is a weak link in the chains and the bells and whistles go off. saying there is an aircraft out there. we don't know where it is all the planes, their flight plan is mandated by knowing where everybody else is. >> it is in europe also at this point. mandated in europe but the problem is you have to get the air traffic control people to comply with the system or buy into the system. the next gen system. the malaysian airline, this part of the country -- or that part of the world may not subscribe to that system. >> again, all of this technology is fascinating. it's one of the things about what happened to 370 is i think viewer and everybody is learning more about stuff in the aircraft that no one know. david, les, appreciate it.

up next, breaking news, a new al qaeda video uncovered by cnn is showing the largest gathering of the terrorist group and officials believe took place in yemen within the last several weeks. details ahead. and sanjay gupta on the front lines of a health crisis in africa. the latest on the efforts to contain the deadly ebola outbreak. hey kevin...still eating chalk for hearburn? yea. try alka seltzer fruit chews. they work fast on heart burn and taste awesome. these are good.

more breaking news, a video that could signal a new round of plotting by ail ka ta. it surfaced on jihadist websites and show a's a top leader addressing 100 followers in yemen telling him he wants to attack the united states. they are not saying if they were caught off guard and didn't know about the gathering or couldn't get a drone there in time to strike it. >> the video is remarkable. the leader of al qaeda in the arabian peninsula and the number two of al qaeda worldwide talking to 100 of his followers. >> isn't it extraordinary? this is yemen. this is the area the u.s. considers the most dangerous al qaeda stronghold. they have tried to attack the

united states before. they vow to try to attack the united states directly yet again. yet, 100 of them, including this top leader and other leaders are able to openly gather and have a meeting and talk. it may be propaganda, it may be recruiting but it is sending a message to the united states, we feel strong enough. we feel secure enough that we can be out here in the open and we're not afraid you are going to attack us. it is a real message. >> there are obviously have been a number of drone strikes and some effective in yemen. any idea of what the video was taken. >> the intelligence committee believes i was taken several weeks ago. one thing that is happening in the video is the top leader is greeting several men that al qaeda broke out of a prison this past winter in yemen. now they are free and he's trying to recruit them in to his

movement even further. they think it was actually in the last several weeks because of that tie to the prison breakout. >> do we know how many assets -- or what sort of intelligence we have about these groups in yemen? was the u.s. aware of this gathering? >> this is the critical question. did the u.s. know about it, or is the intelligence about yemen right now so spotty that they did not know? one of the things that concerns the cia, the white house, the pentagon the most is this al qaeda group has gone underground in its communications to a large extent. they are staying off the internet. they are staying off cell phones. they have gone back to using couriers a good deal because they are afraid of u.s. surveillance of the u.s. intercepting their communications. so this sort of going dark, if you will, is one of the big concerns that the u.s. may not know as much as it wants to

about what this group is up to and didn't know that 100 of them were out there meeting in the open. >> fascinating. barbara starr, thank you. >> sure. >> i want to bring in peter berg in. what do you make of the video? do you think the u.s. could have known about this meeting and not taken action? >> i doubt it. this guy is not only the leader but the number two in al qaeda overall. it doesn't appear from this video there are any civilians in the sequence. they wouldn't take a shot if there were civilians in the area but these appear to be members of al qaeda. this guy is number two in al qaeda worldwide. to me it doesn't make sense they wouldn't take the shot if they had it in their sights. >> this is a group that's been careful about its communications. given that, why would they have a gathering like this, make a video have it out there. >> that is puzzling. as barbara said, this group is relying on couriers and know from news stories in the past

that their electronic communications are intercepted. that's why we have a lot of u.s. embassies closed last year as a result of nsa intercepts. they are being very careful. this flies in the face of being careful because clearly they felt they could do this with some impunity. >> and felt it had some sort of propaganda value. show a display of strength. there's people we don't see in this video who are part of this group, the bomb maker, correct? he's the crown jewel of the group. he's the guy that makes bombs that get on the planes. and he's really gone dark. i talked to senior u.s. officials and he's very, very hard to find. at the end of the day this the guy is more important than anyone else. he's the guy that can build the bombs that can get on planes that are undetectable and he may have trained other people to do the same thing. you do not see him in this video at all. >> do we know how much power this group has in yemen.

a number of people were broke out of prison in the prison break in yemen. >> i think they control good chunks of yemen in 2011. they have taken a lot of hits. something like 100 drone strikes and cruise missile strikes since president obama assumed office. the yemen army has gone after the group pretty aggressively. this videotape actually indicates they feel the pressure is off. for the past couple of years they have been under a great deal of pressure. >> peter bergen, appreciate your expertise. ukraine's military cracks down on pro-russia separatists. is he getting ready to move his troops in. and the race to contain the deadly ebola outbreak in new guinea. who drove to the control room [ woman ] driverless mode engaged. find parking space.

because when people talk, great things happen. new developments in the ebola outbreak. dr. sanjay gupta is there reporting on the efforts to contain this mysterious and deadly virus.

over the last three weeks 112 people have died, 14 health care workers. there's no cure and what makes the outbreak different from others is it reached the capital of guinea, 2 million people not far from an international airport. dr. sanjay gupta reports. >> reporter: about to go inside of an isolation ward in guinea. there's a reason you may not have seen images like this before. these patients are fighting one of the deadliest diseases in the world, ebola. it disarmed their immune system, shut off their body's ability to clot and invaded organs in their body. nine out of ten patients will die. but this horror is isolated. we found traffic to still be busy here. markets are full. children, lots of children, still smiling. you see as scary as ebola is, it's not particularly contagious. it doesn't disperse easily through the air. it doesn't live long on surfaces and people don't typically

spread it until they are sick, really sick. when that is the case the patients are not up walking around on the busy streets. they are in beds, hospitals or worse. even the dead are highly contagious. >> the story is always the same. >> reporter: this doctor from the cdc has helped to trace ebola outbreaks for more than 30 years. >> the risk is not people doing with ebola patient but with regular patient not thinking of ebola. >> reporter: you see it only takes a small amount of the virus anywhere on your skin to cause an infection. as i learned no precaution is too small for the doctors who care for these patients. >> nothing gets in or out. >> reporter: tim is one of the doctors without borders. he's from canada. he comes in to these settings for weeks at a time. he is not married and has no children. that would be a job liability, he tells me.

multiple pairs of gloves and masks. the head is completely covered. a multi-layer gown, boots and pay ron. it is suffocating in the 100 degree weather. preparing to treat a patient with ebola is like preparing to land on the moon but you are the only visitor only person helping them survive. they do this so people outside of these wards and the people on the streets will never know what it is like to be inside. there is confusion as to whether th in the numbers are still going
