such as adsb. a gps system that allows them to do away with radar. what we don't have yet is the coordinating software. a gps system could not have saved malaysian airlines flight 370. that plane was outfitted with adsb. that is why we know most of what we do about its movement. but if it comes together, by 20 - 20 it will be impossible to lose track of a plane in the united states. al jazeera, mountain view, california. >>> there is a powerful front moving through the south east. and that means tornado warnings. kevin is here with that. >> that's right, john. tornado season and severe weather season started later this year because of the cold weather we have soon across much of the area. but now we will be getting into it. tonight i will show you how many we have seen. this is the area we are watching. particularly in missouri. you can see a line of thunderstorms right now. the tornado watches have been extended. the first one here that you see, that one is about to expire. that was for most of the northwestern part of missouri into eastern kansas.

now, there is new technology that is being incorporated into the airplanes all day adsb, or automated dependence surveillance broadcast. it is updated, gps but it is not mandated universally around the world right now. >> greg feith, formally of the ntsb. thank you very much for being with us again tonight. for the families of the missing on flight 370, as you can imagine, this has been an awful few days. imagine not having a shred of information about a family member on that flight. nbc's keir simmons is at the airport in kuala lumpur from where flight 370 originated. good evening. >> reporter: good evening, brian. those who had loved ones on flight 370 have been waiting at this airport for many days now, but not just here. many more have been waiting in beijing, the aircraft's final destination. for family members of those on the missing plane, no answers, no comfort. for some, the frustration was too much. water bottles thrown at airline officials in beijing. "malaysians are liars", one man shouted. others pleaded for calm. most aboard were chinese or malaysian, but there were pass

>> well, an adsb system is not that expensive.ut per airplane, but it's not that expensive. there is a certain amount of expense for the receivers and the people that monitor them, but it's really not that expensive. it's a lot cheaper than having satellite radar coverage. >> so what motivates the faa to be more lenient on this issue? what's allowing that? >> well, i think there's some economic reasons. i think the major airlines are kind of backing off a little bit for while because they see the cost of this thing, and they've got other problems that they need to throw money at. so i think the cost is one of the considerations. >> and mr. kelly -- go ahead. >> i was going to say the faa pretty much does what the major airlines want it to do on this type of thing so that's why they backed off a little bit. >> that's reassuring. i guess the central question here is if there is a high cost associated or the airlines themselves don't want to take it on for whatever reason, given the importance or just by the way the costs, the search

. >> most planes have several pieces of necessary equipment - such as adsb a gps allowing next gen to do away with radar. we don't have the software. next gone could not have saved malaysia airlines flilent 370 -- flight mh370. that's how we know about its movement. if next gen comes together, it will be practically impossible to lose track of a flight in the united states. >> in missouri weather spawned a tornado and several funnel clouds. a twister touched down in the city of trenton, and outside jameson missouri. there has been no reports of injuries, kevin corriveau is here to tell us more. >> we are not over with the storm, it will continue. what we are watching is through missouri, what you show through the video is to the north. now we are dealing with a storm across the central part as well as also in two parts of arkansas river. right now the tornado watch is in place as well as a severe thunderstorm warning. and for st. louis, we are seeing the system go through. we'll see a bit of rain and gusty winds associated with that. in terms of how many tornados we have seep. there's

in the pacific, we have adsb, a satellite uplink down to the ground. there's a better tracking in the pacific ocean. it's where we want to go and we haven't put that infrastructure in yet. >> michael, knowing what you know about the air traffic controllers in cue all la lkual lumpur, did they do anything wrong? >> we don't know. we call it the graveyard shift but those folks are awake. there is not a lot of traffic and they should have known this. more significant, the data package, the till let me met tree. it's inexcusable that at this day and age malaysia decided not to put in that app. we would not be here ten days later had they been reporting continuous information back to malaysia air ops as the air france plane did. we would have had a bear hug with those satellites. >> it's about $10 a flight? >> insequential amount of money. look at the reputation nal costs, hundreds and millions of dollars that we're spending right now. that data package would not have solved this crash but it would have given us a baseline on where to look. >> i guess what

>> the technology is called adsb, which basically tracks airplanes by -- the airplane itself generating part of the next generation of air traffic control. so the technology is already there. you don't need wi-fi in other words. >> i'll tell you what, if i could swipe a card on the back of the seat and say i would like to have flight following and pay $5, i would do it. >> i could send an e-mail to somebody, we're in trouble, something has happened, there's a fire. if one of the passengers had been able to do something, but they were completely wi-fied out. so that option wasn't available. yet the technology is clearly there for all planes to be that way. it seems the airlines are still worried about doing it because there may one day be a crash. there never has been because of wi-fi. >> it felt like there's a conspiracy in action. there's a lot of reasons to not jump to the first leading edge technology. but it needs to be done, it's a matter of safety. you eastern not going to put anybody out of business for telling them to spend $10 extra for a ticket. it's not going to happen. let's

there are other tracking technologies, this adsb system, i believe this plane had that but the ground stations aren't everywhere yet. >> that's my understanding, katie, from talking to a pilot last week, someone who has actually flown this aircraft. the point he made was he called it a data link system and that that system is constantly sending different kinds of information. but it appears from what we know now in the investigation, we do have some information that the malaysian military has now gathered some data. in terms of the investigation, my assumption is they're taking sort of all of these various data points, even when eththey t contact with the plane to try to reconstruct what actually happened. >> exactly. the focus now, notwithstanding all the speculation of what happened in the cockpit, the focus of the 14 countries involved in the situation is to put all the information together from the various sources, when the transponder stopped working, when data control ended and using all the sources, military and nonmilitary, we won't know the full range of that until more infor

it's called adsb. automated dependent surveillance broadcast. it is gps based. it does update every second. it's good for basically ground to ground. we can always track the movement of the airplane. it is intended to replace radar under this nextgen program. it's just slow in implementation. had this airplane had that system on it, as long as it wasn't disabled, because it does use parts of the transponder for sending information out, as long as the system wasn't disabled, then we would have definitely had better tracking of this information -- or this aircraft rather than using ground based radar that once you go out of its line of sight or view, we lose the airplane. >> yeah. once it's not actually having any sort of signal contact with the ground. just let's talk about the size of this search area now. we're talking about 14,000 and potentially 117,000 square miles. if this debris field turns out not to be the plane, is this still the best lead in terms of the geographic area, is this still the best lead for where searchers should be looking? >> i think it i

as far as the upgrade to newer technology, what is called adsb, i think you're going to see that takeber of years to progress. what we're going to find is, i think, the need is there for the new technology. it's just a matter of when. >> john cox, thanks for that information. very interesting stuff. you have been glued to your tvs for the past hour. at least we hope that you have. still ahead, a leading psychiatrist will help explain the fascination we all have with this in air mystery.

adsb is a way of using the gps navigation or gss navigation to fly rather than just based on ground-based equipment. so what next jgen was, during t time i was work on it, the idea we're working on technology in the faa, air traffic control was designed and built back in the 50s and 60s. so it's really tough to say we're still working on this old technology. but nonetheless, we're working on those backs of the ancestors. it's time to move up and upgrade into something new. that's what we're trying to do with nexgen. >> would the airlines have to pay for this, the faa has to pay for this? >> the faa has to pay for it. it's about a 40 to $50 billion investment. congress did approve it. and the faa started the project and they've been working on it. but the attorney general or i think it was the attorney general report just came out recently saying that the faa was as far back as 13 years on some of these projects trying to get 13 years past the schedule to not get them done. some things are on schedule, some things aren't. we'll keep going back to congress to keep asking for more money. con

. >> most planes already have several pieces of the necessary equipment such as adsb, the gps that allowsgen to do away with radar and we do not have the coordinating software and a gps system like next gen could not save the flight 370 and the plane was, in fact, already outfitted with adsb so we know what we do about the movements but if it comes together by 2020 it will be practically impossible to lose track of a commercial flight in the united states. jacob ward, al jazeera, mountain view california. >> stephanie: 6 million have enrolled for health insurance under the affordable care act and 106,000 people enrolled in the first month after the launch and with deadline looming we show you how the administration is coming up, with new ways to get people to register. >> this is what you call a pop-up healthcare sign up center. it's actually in an empty cell phone store and that is the idea here to have a lot of people pass by and see the signs and come in and sign up before that deadline on monday the 31st. given the amount of foot traffic, the place has been busy all morning since it o

or something else happened they should have still been able to find them on radar or what we call adsb them and track them. the fact they completely dropped out of sight is the part that is very strange and that leads me to think either the aircraft was inches instantaneously destroyed, or somebody turned off the electronics in the cockpit because they didn't want to be seen. bill: that is interesting. even with the loss of oxygen in the cabin, and even if you were to glide for 100 miles, you would be able to pick that up because you could follow the transponder right, if the transponder is on, is that what you're saying? >> exactly. the depending on the kind of tracking system they have in malasia, i'm not sure if they're using primary radar, they could actually see a return from the actual airplane with the transponder off. they didn't even see that. so again, we're going to have to start expanding the search. i think we'll also have to start expanding our ideas, that maybe if we thought we knew what happened, maybe we need to look at things maybe didn't seem very likely. bill: how m

through the entire flight and we could track an airplane such as mh-370 if it had been equipped with adsb>> greg, what do you think happened? >> i firmly believe right now that this was -- and we've talked about it all week. i was relatively certain of this when i first saw that hook in the radar data, that that had to be human intervention, that wasn't a preprogrammed track many the autopilot because they were heading to beijing, and that the autopilot isn't smart enough to try and turn itself around if there was some sort of explosive decompression and the pilots pass out, the autopilot doesn't have that kind of functionality. it took someone actually reprogramming or actually turning off the flight management system and manually flying the airplane either through the autopilot or hands on the control to make that turn and fly it away from its destination. >> to conceivably land it someplace? is that a plausible explanation for you? >> it isn't a plausible explanation for me only because this is a very large airplane, 600 to 650,000 pounds. it's not like you can put it down in a jungle

and we can't quite tell yet if it's complete radar coverage or if it's what we call adsb, which is as. but they would be looked at maybe every minute or so and for it to just disappear and never see it again at all, that's very, very odd. >> it's odd and would it be possible for it to happen without an air traffic controller knowing it or us understanding it? >> sure. that is possible. when air france 447 disappeared, of course, it was in a much wider stance of the south atlantic, but again, the air traffic radar again -- and i'm not completely sure where it went down, so that's why we're a little hesitant about how much information has been -- it looks at the aircraft differently. but again, it's just so strange that there wasn't any kind of update after that -- i should say that last hit. >> yeah. a jet liner doesn't just disappear from the sky. everybody is wondering what possibly could have happened. they've expanded the search from 20 nautical to 50 nautical miles. some experts say there is a possibility that almost just evaporated and gone into bits. what is the evidence of the

i think after this particular event, i think there has to be a discussion about implementation -- adsbgps-based tracking system, which is eventually going to replace radar, part of the next gen program, i think this is really going to spawn accelerating that timetable, because right now it's out to 2020. some airplanes are equipped with it. it updates itself every second. it provides information to air traffic controllers. and it gives us ground-to-ground tracking of the airplane. so unlike the radar, where it's ground-based, has to look up and see the airplane, this gps is going to bounce it off the satellite, so no matter where this airplane goes, it's always looking down on it. we should find it, unless it's in a very remote canyon that has a lot of -- a lot of obstructions that blocks the gps signal. >> so just one point on the transponders, and i agree with you, there will be changes both with the use of transponders now and the acceleration of asb but remember one thing about this. even when the transponder was turned off, it could still be tracked by civilian radar. it was less

. >> well, you know, i go across the north atlantic quite a bit, a system, adsb a ground-based systemtellite. we're always tracked. this is amazing that this whole in this part of the world could provide this system. this technology is already there. my airline reeves constant data about almost every aspect of altitude, air speed. almost everything. location is never an issue, where the airplane is. >> tim, this black box, do you believe that these are good enough? everybody's been talking about the race against time. 30 days, and then there's no ping. on some level, it shows that -- that we as human beings think, oh, we can find a plane. 30 days is plenty of time. >> yeah. i think the beacons can be expanded on time. i put assets underwater that cost hundreds of thousands sometimes millions of dollars or multimillion and they have beacons on there that will last 6 months, 8 months. it's -- >> realistic? >> yeah, well, i wand to find it. if i lose it i want to find my gear and so does the insurance company. so i think, yes. they can be expanded at least how long they last. >> your com
