in the air and for first time under the water. kyung lah is at the stabging ara in perthwolf just about this time that the very first of the planes take to the air. we've got gnot gotten any detai about what the air search would look like. but what we did see yesterday was a total of 14 planes taking to the air. now we have those underwater vessels, those towed pinger locator, one from the uk and one from the united states. it's a meticulous painful search underneath the water. it will be supported by a heavy air presence. just like we heard rene mention, wolf, it is from the air that they are most hopeful that there will be something spotted to give those locators a place to go. >> and weather conditions, i assume, are okay today, right? >> okay is the best way to put it. the weather is actually not going to be as excellent as it was yesterday. yesterday had terrific visibility. today the weather is going to be a little bit worse from the south, there is a weather system moving in. it will cause a little more cloud activity there, but we should point out it is still goin

in the next few days and they may have already run out. you really are on a race against time. kyung lah live in pertha. >> what i can tell you is that it will be held by angus houston. the man in charge of this entire operation. his first substantial news conference since he took control of this operation on sunday. we know that the timing will be mid-day australia time in the next four to five hours, but we don't know exactly what he is going to be telling reporters. we are being told that this is going to be like a regular news briefing but his very first to us. whatever he does say, it will be important to the some 1,000 sailors at sea. approximately 100 crew people up in the air. this has been a relentless search with hundreds of family members waiting for word around the world, and, erin, it bears some importance that we should remind people, no debris has been found and in 2014 it is still possible for an airliner to comp pleatcompletely vanish trace. >> in terms of the search area, obviously, slightly shifted and i know you talk about this press conference is substantial and we'll find out why

kyung lah on the scene in perth, australia.g me now, former ntsb managing director peter goelz and miles o'brien and cnn law enforcement aanalyst tom fuente. >> we are skeptical but i hope what they've got is some slight indication of a ping that directs their surface vessels with the towed son n sonar. that's what i'm hoping for. that it's not just supposition. >> if theaf ping from one of the flight data recorders, that would be a big announcement. >> huge. that would be worth saying it's a big announcement. >> because at that point, tom, you could really direct the search to a specific location and hopefully locate it. >> wolf, if they are announcing that they have a big announcement and they don't have anything that significant, what a huge mistake to get everybody excited yet again. >> what do you make, miles, of all of this? because earlier there have been several points over the past four weeks, we've been pretty up beat that something is about to break and we've been disappointed when it didn't. what did you make of thi

. >> let's go to perth, australia, for more on the search operation that's about to begin. kyung lah standing by with the latest on that. what's going on in perth right now, kyung? >> well, the very first of the planes has indeed taken off. we understand just getting this latest news from the australian authorities that there will be a total of ten planes in the air today, nine ships that remain at sea. this is very much like the other days that we've seen prior to this. it will be a comprehensive search we are told. those planes flying low to the sea. mowing the sea back and forth, looking for any sort of debris. and we understand also, wolf, that there will be a big news conference regarding the operations of this search. we do not know what the content of it will be, but we understand that it will be some sort of new detail regarding what this search is going to be looking like. wolf? >> we'll stand by for that. as long as we learn what is going on, we'll share it with all of our viewers. the weather, i take it, is much better today? they should have relatively clear skies, relatively calm waters? >> absolutely. we've heard that the we

kyung lah is joining us from the staging area in perth, australia, with more of what is going on. what is the latest, kyung? >> reporter: well, in just about the next hour, the air search is about to resume. they are basically combing the area back and forth and we are getting that late word that a uk british nuclear sub is joining the severaarch area. it's going to lend some extra hands to the search, at least putting eyeballs under the sea hoping to find the wreckage as quickly as possible. wolf? >> kyung, there were sobering words coming from officials today. share some of them with us. >> reporter: sobering and quite blunt. basically, the men leading the operation saying, look, we are not going to find this very quickly. he is saying this is based on inexact science off of those blurry satellite images that we've been showing. he says, we need to look at this as a long game. here's what he said. >> we need to pursue the search and continue to do that for some time to come. but inevitably if we don't find wreckage on the surface, we are eventually going to have to probably in co
