Relatives who one of our crews met outside a residential building here that in fact patrick was the man who was steering that plane. Patrick sondenheimer. Weve known from lufthansa that he was a captain who had been flying with the airline both lufthansa and germanwings as well as another German Airline called condor for ten years. He had 6,000 flying hours. By all means a very very experienced pie lt. He was also the one who tried to get back into the cockpit, first knocking a little bit normally obviously and then trying to kick the door down in the end as the plane descended down there. So we know his identity now. We have talked to his relatives, but they at this point say they are not comfortable speaking in front of the camera because, of course they are still in a state of grief, fredricka. And what about those who knew, the copilot particularly the girlfriend who has been quoted in a german newspaper there in interviews. What more is being said . Reporter well theyre trying to piece together a mosaic of what this person was like and what might have driven him to do what he apparently did, which is of course fly that plane into the side of a mountain and the largest tabloid here in germany has an interview with an exgirlfriend of his. She claims that she was together with lubitz for about five months last year. She describes him as someone who needed a lot of attention, who was very sensitive, someone who could also be quite flattering to her, who often gave her flours. She apparently was a Flight Attendant on germanwings as well but also someone with a very dark side she said. Someone who would become erratic, someone who often fought with her, who became very angry when he spoke about the company and someone who had very bad dreams. Now, of course its unclear what all of this will mean to the investigation but its certainly something where theyre trying to piece together a profile of this person to try to determine why he did what he did, fredricka. Any more about the doctor who wrote the note that investigators say they found a torn up note that said he was unfit to work. Any more from the doctor even . Reporter well the doctor is certainly someone that authorities are speaking to right now. Its interesting because the New York Times just a couple minutes ago came out with a new report saying that they have information that apparently lubitz was getting treatment for some sort of eye problem that might have been a jeopardy to his flying career. They say they have that from two sources and its interesting because weve been speaking to the University Clinic in dusseldorf and theyve acknowledged that lubitz went there twice this year to get diagnostics, and they said it was not for depression related issues. Its still unclear at this point in time but certainly the doctor that treated lubitz is someone that the authorities will very much be speaking to at this point in time. Its interesting because the medical records that were found inside lubitzs apartment indicated he had been getting treatment for an ailment for quite a while. This was an ongoing process and hed already had several of these sick notes that said he was unfit to go to work which, of course, for a pilot means he is unfit to fly and that he destroyed several of those, of course tearing some of them up. They were later found in that apartment. The prosecutor here in germany has not said what kind of an ailment lubitz had, whether it was a depression whether it was maybe something with his eyes or some sort of other physical ailment. Were still trying to find out more official information from the authorities, but certainly it appears as though it might have been multiple things he was suffering from. There are outlets reporting he suffered from ge pregnancy redepression issued in the past as well. Thank you. Keep us posted. How will investigators piece together all this investigation particularly about the copilots history . Lets bring in our panel right now. Peter goelz is a cnn aviation analyst. Jonathan gilliam is a former air martial. Mary ann tool is a special agent and les abend is a contributing editor of flying mag zenazine. Good to see all of you. Peter, you first. We know this was this note investigators found and said he was lubitz was unfit to work. What are the medical or maybe even mental conditions that would cancel out someones ability to fly a plane . Well theres a wide variety of conditions or situations which would disqualify somebody from flying. For instance the faa has a list of knockout medications that if youre taking one of these medications you may not fly a commercial airplane. There are medical conditions such as diabetes that the United States views as a nonstarter. Pilots cannot be taking insulin and have certain stage diabetes. So theres a wide variety of both illnesses and pharmaceuticals that would prevent you from getting behind getting into the cockpit. And then when we hear les, that possibly at least according to the New York Times times, that there may have been some eye treatment that this copilot may have recently sought, what kind of eye problems perhaps would fall into the category of being simply unfit to work . Well i mean theres certain vision standards we have. We have to be at least in the United States we have to have it correctable to 20 20, but it goes beyond that. We have to understand that most of the faa limitation that is keep us from flying are self disclosure things things as simple as a common cold. We self disclose im not good enough to fly. When this gentleman allegedly went to a doctor for a vision issue, this was just a standard medical doctor for that particular issue. He is not required to disclose that to their version of the faa nor is the pilot, in this particular case the copilot required to disclose that. If it was a medical examiner specifically under the guise of in our country the faa, that would have to be disclosed if it has the potential for disqualifying for flight. And then mary so much is trying to be uncovered about who he was by talking to his girlfriend according to a german newspaper, perhaps even his family members would be able to reveal a bit more about his behavior but aside from the medical conditions that there is a track record there will be doctors who will be able to uncover that. What perhaps observations might this airline be responsible for in your view in observing whether he was someone to be trusted in the cockpit . Well often times people that have Mental Health issues are really able to present quite well and present quite normally so just visually looking at someone or even having a conversation if they have good impression management skills if they know hey, i have got to come across as really normal and plugged in they can do that and thats why self reported information can be so unreliable. To me whats so interesting here is if this person was so attached to this job, he voluntarily went to these doctors. Most often you see or very often you see people with Mental Health issues really stay away from doctors because theyre afraid of what theyll hear so that tells me this individual this copilot did not anticipate the medical findings that evidence going to receive. And, jonathan while this may have been the practice to self report i think any layman would begin to think, well if you feel like you have a condition that is going to mean that you can no longer put food on the table, you wont draw an income from this particular profession then youre not going to report that information. Does it seem maybe that it turns to the culpability of an airplane or even an industry to allow that kind of routine to be in place . Well as mary can tell you in the federal government, you know, were watched heavily in everything we do so its more than just Self Reporting. And Self Reporting, i guess it does play a part in certain things but when youre talking about depression or youre talking about somebody who has suicidal tendencies and we have to look at these two Different Things, you know somebody who is depressed will typically isolate themselves if theyre going to commit suicide. Somebody who has something going on inside the exterior in their family where theyre having a problem with their job they will a lot of times end up acting out and taking other people with them. And these are, as mary said these are things you may not be able to catch if youre trying to find it and its not things people are going to want to report as well and i know from being a s. E. A. L. Or being in the federal government you dont want to report illnesses a lot of the times because you may get taken off of something. Peter, it would seem there are an awful lot of people he would come into contact with at lufthansa or germanwings, people who would be able to make their observations or might this be the case that he has this incredible ability to kind of mask his condition or mask his unfitness to work . Well the whole issue of voluntary reporting is going to be reexamined i think because of this accident but youre right. Mary helenellen hit it these are guy that is can present well and particularly if whatever malady he was facing was a careerender particularly to a career that he had wanted his whole life its really a very difficult thing to come to terms with that. But i think the whole issue of how do you self report a problem and not have it be a strike against you in your career is very challenging, and so far we have very superficial responses to that. Okay. All right. Were going to talk with all of you later. I want to talk more about how standard is that Self Reporting. Is that something that is commonly practiced here in the u. S. Or is that something thats respected by the Aviation Community worldwide. Peter goelz, jonathan gilliam, mary ellen, les, thanks to all of you.

Com the crash of flight 9525 has taken a toll and the families of the victims, relatives, and friends of the deceased gathered today in an area near the site where there loved ones died. They held prayers. There is a village there serving as a staging post for the recovery operation. Loved ones brought flowers and pictures as they mourn the lives lost. Cnns karl penhaul joins us from the crash site. You made your way to the crash site which we understand the terrain is very treacherous. Did you it on foot right . Tell us how difficult that was. Reporter thats right, fredricka, and the reason we did it was we thought it was so important to get to an area close to the crash site obviously without trampling on a crime scene. But to take a look and to try to understand a little bit better why this operation is so treacherous and why the recovery both of human remains and also fragments of the plane could take days or even weeks according to the investigate guy fors. It was you have to going. We did get there. Lets take a look at what we found. Swinging on a wire they recover the remains. Hundreds of feet below emergency crews cling to the mountainside just so they dont fall. Investigators say the speed of the crash pulverized the plane and passengers. The recovery operation they say is bit by bit, bag by bag. You can just pick out the small red flags rescuers dig into the earth when they discover new fragments. And that looks like a scorch march. The french prosecutor said the plane hit the mountain bounced off, and then disintegrated. Its a tough hike through rugged mountains and steve valleys. Still a little while before dawn but were going toward a trail head. In order to understand why some rescuers describe this as their biggest ever challenge, we try to get closer to the crash zone. There was a little frost this morning. Now the sun is coming down certainly no sign of snow just yet. Few people accept except shepherds live up here. Conditions are too inhospitable. Get getting up here is literally hanging onto tree roots and grass. You can see why theyre going to have to fly anything out of that crash site by helicopter. The whir of rotor blades helps us pinpoint the site. We see forensic teams working with expert mountain yearseers to keep them safe. High winds make flying treacherous. Saying farewell is never easy but perhaps those grieving could find a little consolation amid these crags, peace of the running water, peace of snowcapped peaks, peace to loved ones lost. I can understand that relatives may feel that as this recovery operation drags on that they could get a little frustrated at the pace of it but having seen that work yesterday, if it is any consolation to them the rescue workers are doing their damnedest to get the human remains outs and get them ready for burial. It almost appears at some stages the forensic investigators are clinging on with their fingertips to that mountainside so they dont fall off. The helicopter pilots as well. My colleague Nic Robertson had been talking to one this morning, and he said when his helicopter was getting buffeted by winds so hard yesterday as he overflew those gullies and ravines ravines, he looked away from his control panel and looked at the birds there and a piece of string he had hanging in the cockpit really to get his bearings and judge the winds by his natural surroundings.
