looking at this video. this is an example of what the searchers are up against in this part of the world in the southern indian ocean. let me tell you about this. another big development. we also know they tracked the plane via a series of pings. we are learning the last one heard is a mysterious partial pinni ping, could be triggered by outage of power, perhaps as it was hitting the water. let s go to a senior correspondent in kuala lumpur. you talk about this potential lead, possible debris field, the real question is when are they getting out there to find the actual debris? reporter: right. so what s happened is the weather has been particularly bad. they had to ground some of the flights at some point this week. we do know that today was a good
for hours in some sort of controlled flight. you know, we talked to one very experienced triple 7 pilot that said there are a lot of catastrophic accidents, but planes don t typically fallout of the sky. even industry people are sort of looking at this notion it has to be said, brooke, there is no evidence, no evidence at this point as far as anybody knows that ties the pilot or co-pilot to this. there is no stated motive. none of that. this is certainly an idea that we are increasingly hearing people are investigating, considering, and looking at. brooke? we talk about theories, coalescing in the cockpit, could be key to get the files and hard drives with the fbi in a couple of days. barbara starr, thank you so much. sure. and some of the most critical information may actually come from the pings the plane sent after it dropped out of radar. we know that there was this partial ping, this is what we re talking about today, a partial ping that the plane sent out. that was its last
hearing a pilot say this could be a hint to what happened. why could this be a big deal, what could a partial ping be, when a plane hits the water? the ping aspect is above my pay grade. it is incredible what these folks forgive me for throwing that at you. no, it is fine. where i was going with this is that to me, i discussed this on another program was that it is possible that that might have been the last engine that burned, ran out of fuel. when that happens, the airplane is designed to automatically deploy a system, a rat as we call it in the business, and that will allow for electricity and some hydraulics. so what it could have indicated was a transfer of power, very quickly, because that bus may not the bus that powers that satellite system that created the ping may not be on that emergency rat system, if that
satellites do not collect imagery over oceans. most satellites weren t tasked to do that. thank you for the expertise, i truly appreciate it as we watch the biggest lead so far. the missing jet sent a partial ping. my next guest says it could mean a fire on board. he ll explain that hypothesis. also, we show you inside this flight simulator. in a matter of moments, you re about to get a look at the underwater vehicle that could find this missing aircraft. we will show you how it works live. this is cnn s special coverage. you really love, what would you do? [ woman ] i d be a writer. [ man ] i d be a baker. [ woman ] i wanna be a pie maker. [ man ] i wanna be a pilot. [ woman ] i d be an architect. what if i told you someone could pay you and what if that person were you?
worry about it sinking to the bottom. it is going to be attached to a large piece of airplane even in the gooeyest bottom sit on the top awhile and give us a fair chance to find it. what about the cockpit voice recorder. same location, same rules. okay. what about the other nugget, learning about a partial handshake, ping, ping. the airplane is going 560 miles per hour. if it narrows it down to an hour, you have it narrowed to a tight area. if it is a ping at impact, we are getting closer to a smaller area. if it is within an hour or half hour, the airplane still covers a tremendous distance. shawn, you re looking at all of this, you know accidents. what s the one piece of the puzzle you really want answered? i want to look at how the airplane hit the water,
