joining me now to explain all this is the senior director of geospatial big data and john mcgraw.lso a former federal aviation administration official. explain what digitalglobe does and its relationship to this ongoing search question mark >> thanks for having me. digitalglobe owns and operates commercial satellites and they are constantly orbiting around the globe capturing imagery. as soon as we heard about the event, our satellites captured imagery over the search area. we are releasing it to the public. we have millions of people on our website right now looking and trying to identify things that look out of place. >> john mcgraw, based on your experience, does this make sense? >> i think it does. having that many people looking at the imagery is a force multiplier. none of the government agencies would be able to bring that many people to bear with all the off the shelf imaging tools and tools to analyze the images they have today. i think it is a tremendous help. especially with the uncertainty we have around the path of this airplane and where it might have gone down. the

joining me on the phone john mcgraw. good to have you with us.e developments and the possible flight path, what comes to you? >> this is obviously the most probable area the airplane could go down. the ntsb early on, days ago, determined this is the most probable path the the debris is in the right area. i also know from having participated in active investigations that often there are promising leads that don't pan out. there's a lot of debris in the ocean. finding something of this size in the area the promising. >> obviously, we have been cautioning people that we've had these situations before where they saw something or thought they saw something on satellite imagery. certainly officials are saying they are cautiously optimistic. from your perspective, how long do you think it could be, based on your experience, before they have a good take on whether or not this is indeed a piece of that plane? >> i think the moving aircraft overhead which will have some pretty sophisticated sensors. they may be able to see features on the debris that will

i think there will be an increased push to install in a much more widespread way. >> john mcgraw and commander burgiss, thank you for your time. >>> clouds and fogs made spotting that debris even more difficult. we continue next with the weather conditions crews can expect when they rue term. >>> join the conversation. go to @tamronhall, @newsnation. let us know some of your questions.

we are also joined by john mcgraw.an, what happened to the transponder that helps air-traffic controllers track the airplanes? >> it is a huge question. we are talking about the emergency location transmitter. it is also called the elca. it is made by honeywell. investigators do not know why it went dark after takeoff. it sends out a signal on impact. pilots can manually activated. it did not work. it never happened. haveexperts say it could been caused by a huge explosion. separate from that, you have the black boxes that we talked so much. they are also made by honeywell. honeywell said this plane was equipped with two. they are actually orange and not black. one was the flat -- flight data recorder. wing movements, anything going of the engine. that you have the cockpit voice recorder. that does exactly what it says these are supposed to be sending out signals for 30 days after a crash. they can do that underwater for more than two miles underwater. that is what investigators are really hoping is found here. so far,

official john mcgraw, look at this board and your thoughts on it. >> well, sean, sorry i can't see the board, let me get it turned around here. >> what we were describing to you that is really quickly here that it made this turn and it would be 1500 miles perhaps about here. we draw a straight line down that it went in that direction. the location where they're now searching off the coast of australia. >> well, you know, i completely agree with the previous guests that you have to look at every scenario at this point. we really don't have anything that we can rule out at this point. i think that the most probable outcome is that the airplane went south and continued south until it ran out of fuel. the satellite data that we have continued, i think that is probably the best data that we have. and so it is okay that they're focusing down south. it does not mean they should stop the rest of the investigation. that has to continue because there could be other answers for why the satellite continues -- >> michael shakes his head, he agrees. philip, let's get your in put. what are your thoug

joined by a john mcgraw. he is a former ffa official.ister provided some closure of the victims. at the same time it, there were some signs that perhaps a breakthrough with sightings of debris at sea. is there anything we could give us a sense of certainty as to what happened to the flight? >> i think you will hear more details in the coming days. we are talking specifically about what kind of satellite data they used to confirm the track of the aircraft. people need to understand that this is like a criminal investigation. all leads are followed until they run out. the most probable leads are the ones that are focused on. now they will be able to focus all of their activity on a specific area because the other leads of played out. >> here is another question. conclusivelyablish that the data suggests that the plaintiff took a southern route toward the southern indian ocean , many thousand kilometers off yesterday and coast, is there any sense that we can determine no airport nearby. there are no islands nearby. it is empty ocean for tho

john mcgraw from the transportation security administration, he joins us from annapolis, maryland.have you with us. we have seen the news from malaysia where they are beginning to interview the pilot. do national security authorities review pilot safety as well as passenger security? they do, in coordination with the airlines. that has been a controversial piece here in the united states, in that pilots and crew are screened in a different way than passengers are. , some inat passengers the united states have been critical of that. but airlines do certify to tsa that all the background work has been done on these individuals, all the employees. and the whole point has been said -- why do you want to review us so closely when we are in control of the airplane and can take us down -- take it down? that statement has just been made. the point is, you need to consider and be scrutinized by every -- and scrutinize everyone. this is so unfortunate for the families that this has dragged on. but come and you know, each time as an investigator -- that is my expertise. >> we had on yesterday

we go to john mcgraw. he assisted us yesterday with perspective on airlines as we look at this tragedy in the south china sea. cockpit,nto any given given over and over ocean flight. howling charlie over a wide ocean -- how linked are they to over a wide ocean? do they know where they are in do we know where they are on any given flight? >> well, yeah, they do. pilots have multiple systems where they can communicate back to land. satellite or high-frequency radio. there are number of ways they can communicate. that is the ministry. not only to communicate, but after layer after layer of logical redundancy. there's even a deployable turbine that drops out of the side of the airplane that produces electricity. there are many ministries here. >> i don't want to speculate and rumor in that, but is the telemetry of the south china sea or the malacca strait, the same as going from new york to london? are we more wired up across the atlantic ocean and in the agencies? sees?n >> they should have the same durabilit
