Rescuers still to find plane’s flight data recorder, leading to growing calls for caution in blaming co-pilot Andreas Lubitz for deliberately downing the aircraft 
 
 Forensic teams have identified 78 distinct DNA strands from body parts spread across the remote mountainside in the French Alps where Germanwings flight 4U9525 crashed, killing all 150 people on board. 
 
 Rescuers are still, however, to locate the plane’s second black box — its flight data recorder — six days after the Barcelona to Düsseldorf flight crashed into a rocky ravine at 435 miles (700km) per hour. 
 
 Between 400 and 600 body parts have been located and are currently being examined. 
 
 “We haven’t found a single body intact,” said Patrick Touron, the deputy director of the police’s criminal research institute. Identification experts were using dental records, DNA samples from family members, fingerprints, jewellery and bits of ID card to help the process. 
 
 The black box, which is actually orange and weighs around 10kg, was originally in a protective casing, but only the empty casing has been found. 
 
 Captain Yves Naffrechoux, a mountain ranger, told Agence France-Presse: “If it has not been completely destroyed or pulverised, the black box will be under the rubble and debris. We must work with caution and a lot of precision. We have to look under every last bit of plane and lift every rock.” 
 
 An access road was being built to the site to allow all-terrain vehicles to remove some of the larger parts of the plane. 
 
 Prosecutors in France and Germany have suggested that the co-pilot, Andreas Lubitz, deliberately crashed the plane. They have retrieved a torn-up sicknote from his flat in Düsseldorf, which was dated for the day of the disaster. Lubitz, who is from the small German town of Montabaur, had a history of depression which he hid from his employer and colleagues, they said. 
 
 
 
 The suicide-mass murder theory is based on the cockpit voice recorder retrieved from the crash site near the village of Le Vernet. According to Germany’s Bild am Sonntag newspaper, the captain, Patrick Sondheimer, asked Lubitz to prepare the plane to land in Düsseldorf. Lubitz responded “laconically”. Sondheimer then left the cockpit to go to the toilet, telling his co-pilot: “You can take over.” 
 
 
 
 There was a sound of a seat being pushed back, and the door clicking shut. According to Bild, the plane then went into a steady descent. Minutes later there is a loud knocking and the voice of the captain saying: “For God’s sake open the door.” In the final moments the screams of passengers can be heard. 
 
 
 
 German and European pilots’ associations urged caution last week in stating the cause of the crash until the second black box was discovered and the air accident investigation brought to a conclusion. 
 
 
 
 Jean-Pierre Michel, the head of the French investigation agency, said that some technical details of what precisely happened to the Airbus A320 aircraft were still missing. “At the moment we can’t rule out the hypothesis of a technical fault,” Michel told the French channel BFM TV. 
 
 The German chief executive of the Airbus Group, Tom Enders, expressed his irritation on Sunday and criticised TV talkshow coverage of the disaster. “There has been speculation without facts, fantasy and lies,” Enders said. Such “outrageous nonsense” mocked the victims, he added. 
 
 
 
 In Montabaur, where Lubitz lived part of the time with his father, mother and younger brother, prayers were said on Sunday for the victims of the crash, and for the co-pilot and his grieving family. Hundreds of worshippers packed into St Peter’s Catholic church on the town’s cobbled main street, on a morning of pouring rain. 
 
 
 
 Many there believed that investigators had been too quick to blame Lubitz for the disaster. Candles and flowers have been left outside the church, and one note read: “We think of all victims of this tragic crash, and their families and friends, in these difficult hours.” 
 
 The priest expressed sympathy for Lubitz’s parents whom, he said, had found themselves “at the centre of attention”, the families and friends of the victims, and the rescue workers in France. ||||| Andreas Lubitz, 27, was living with the unnamed 26-year-old woman in his Düsseldorf apartment up until the crash last Tuesday, Germany’s Bild newspaper and Der Spiegel magazine reported. 
 
 She worked as a teacher at an unnamed comprehensive school in the state of North Rhine Westfalia and Bild said she had told her pupils that she was pregnant. Lubitz had also recently ordered two new cars for them. 
 
 The woman – given the pseudonym, Sabine L, by Bild to protect her identity – visited the crash site last week, discovering on the way there that Lubitz had deliberately crashed the plane, killing himself and 149 others. 
 
 Sabine was said to have met Lubitz when the two were school students doing holiday jobs at a hamburger restaurant. “Eventually they no longer kept their relationship a secret,” the former manager was quoted as saying. 
 
 It is thought that Lubitz deliberately crashed the plane because he was deeply depressed and was being treated for vision problems that could have ended his flying career. Some sources suggested he was suffering from a detached retina. 
 
 The reports came as a transcript of the last voice recordings was revealed yesterday, which reveals that Lubitz urged the pilot to go to the toilet, leaving him alone in the cockpit. Passengers can be heard screaming uncontrollably for minutes before the crash, according to details published by Bild am Sonntag. 
 
 Over the course of the transcript, Lubitz can be heard telling Captain Patrick Sondheimer that he is ready to take over “any time”. 
 
 As Capt Sondheimer orders Lubitz to prepare the plane for landing in Düsseldorf, Lubitz appears to give clues about what he is about to do, responding with “hopefully” and “let’s wait and see”. He then tells Capt Sondheimer: “You can go now”. 
 
 Two minutes later, the Captain says, “you can take over now” and the sound of a cockpit seat sliding backwards is followed by the clicking of the cockpit door. 
 
 Shortly after, Lubitz puts the aircraft into descent mode. Air traffic controllers can then be heard trying to contact the plane and the automatic “sink rate” alarm starts sounding. 
 
 Seconds later, there is thudding on the cockpit door. Capt Sondheimer can be heard shouting, “For God’s sake open the door!” Behind him, passengers can be heard screaming. Among the last sounds appear to be attempts by Capt Sondheimer to break down the door with the aircraft’s emergency axe, as he shouts: “Open the goddam door.” But to no avail. Shortly after, the plane’s wing is heard scraping the side of a mountain. French officials have refused to confirm or deny the transcript. ||||| Image copyright AFP Image caption The German tabloid Bild carried an interview with the ex-girlfriend of Germanwings co-pilot Andreas Lubitz (pictured) 
 
 The Germanwings co-pilot thought to have deliberately crashed his Airbus in the French Alps, killing 150 people, predicted "one day everyone will know my name", his ex-girlfriend says. 
 
 In an interview with Germany's Bild newspaper, she recalled a comment Andreas Lubitz made last year. 
 
 "One day I'm going to do something that will change the whole system, and everyone will know my name and remember," he told her. 
 
 Flight 4U 9525 crashed on Tuesday. 
 
 The woman, a 26-year-old flight attendant who flew with Lubitz for five months last year, was "very shocked" when she heard the news, the paper says. 
 
 She is referred to only as Maria W.

 If Lubitz deliberately brought down the plane, "it is because he understood that because of his health problems, his big dream of a job at Lufthansa, as captain and as a long-haul pilot was practically impossible," she told Bild. 
 
 Meanwhile, German newspaper Die Welt said that investigators had found evidence of a serious "psychosomatic illness", and that Lubitz had been "treated by several neurologists and psychiatrists". 
 
 Several medicines used to treat mental illnesses were found at his home, but there were no signs of drug or alcohol addiction, the newspaper, citing an unnamed investigator, said. 
 
 Separately, the New York Times, citing officials, reported that Lubitz had sought treatment for eye problems.

 'Too much pressure' 
 
 French investigator Jean-Pierre Michel also told the AFP news agency that the pilot's personality was "a serious lead [in the investigation] but... can't be the only one". 
 
 "We're going to try to understand what in his life could have left him to carry out the act," Mr Michel said, adding that investigators had not discovered any "particular element" so far. 
 
 The black box voice recorder indicates that Lubitz locked his captain out of the cockpit on Tuesday and crashed the plane into a mountainside in what appears to have been a suicide and mass killing.

 German prosecutors say they found medical documents at Lubitz's house suggesting an existing illness and evidence of medical treatment. They found torn-up sick notes, one of them for the day of the crash. 
 
 They say he seems to have concealed his illness from his employers. 
 
 His former girlfriend told Bild they separated, "because it became increasingly clear that he had a problem".

 She said he was plagued by nightmares and would at times wake up screaming "we're going down". 
 
 She added that he became stressed when they spoke about work: "He became upset about the conditions we worked under: too little money, fear of losing the contract, too much pressure." 
 
 A hospital in the German city of Duesseldorf has confirmed Lubitz was a patient there recently but it denied media reports that he had been treated for depression. 
 
 Lubitz's employers insisted that he had only been allowed to resume training after his suitability was "re-established".

 Who was Andreas Lubitz? 
 
 'Unfathomable loss' 
 
 A fellow member of the flight school where Andreas Lubitz took lessons told the BBC the co-pilot had known the area of the French Alps where the plane crashed from going there on gliding holidays. 
 
 A French newspaper, Metro News, reported (in French) that Lubitz had holidayed with his parents at a flying club nearby. 
 
 French police say the search for passenger remains and debris on the mountain slopes could take another two weeks.

 Relatives of some of the passengers and crew who died, including the family of the captain, have visited Seyne-les-Alpes, near the crash site. 
 
 In the aftermath of the crash, the EU's aviation regulator, the European Aviation Safety Agency, has urged airlines to adopt new safety rules. 
 
 In future, it says, two crew members should be present in the cockpit at all times. 
 
 Lufthansa and Germanwings have taken out full-page notices in German newspapers, expressing their "deepest sympathy" and condolences for "the unfathomable loss of 150 lives". 
 
 What is depression? 
 
 Depression is more than just feeling a bit down for a few days. It is an illness which, at its most severe, can leave people feeling that life is no longer worth living. It can cause physical symptoms such as headaches, sleeplessness and constant tiredness which may last for months and months. 
 
 People with depression can also feel anxious, irritable and agitated on a daily basis but it affects everyone differently and only in rare cases is it a reason for violence against others. 
 
 If people admit their symptoms and talk to someone about their feelings, depression can usually be treated but the biggest barrier to getting help is often stigma and the fear of disclosing mental health problems.

 Source: Aviation Safety Network ||||| Marseille, France (CNN) Initial tests on the flight data recorder recovered from downed Germanwings Flight 9525 show that co-pilot Andreas Lubitz purposely used the controls to speed up the plane's descent, according to the French air accident investigation agency, the BEA. 
 
 The flight data recorder, or "black box," was found Thursday by recovery teams that have spent days since the March 24 crash scouring the mountainside in the French Alps where the plane went down. 
 
 A statement from the BEA on Friday said its teams had immediately begun to investigate its contents. 
 
 "The initial readout shows that the pilot present in the cockpit used the autopilot to put the (airplane) into a descent towards an altitude of 100 (feet) then, on several occasions during the descent, the pilot modified the autopilot setting to increase the speed of the (airplane) in descent," it said. 
 
 "Work is continuing to establish the precise history of the flight." 
 
 Evidence from the plane's cockpit voice recorder, recovered swiftly after the crash, had already led investigators to believe that Lubitz acted deliberately to bring down the plane, killing all 150 people on board. 
 
 And prosecutors in Germany said Thursday that an analysis of a tablet device retrieved from the 27-year-old's apartment in Dusseldorf revealed that he had researched suicide methods and cockpit door security on the Internet. 
 
 The correspondence and search history on the device demonstrated that the co-pilot used it from March 16 to March 23, Dusseldorf prosecutor Christoph Kumpa said. 
 
 The search history was not deleted and also revealed searches concerning medical treatment, the prosecutor said. 
 
 DNA profiles 
 
 Investigators have focused on Lubitz's health as they try to establish his motivation. 
 
 But the missing "black box" was expected to yield important evidence about the plane's final minutes. 
 
 A female police officer digging by hand for clothes in a ravine that been searched previously found the flight data recorder Thursday afternoon about 8 inches (20 centimeters) below the surface, Marseille prosecutor Brice Robin told reporters. 
 
 Usually white with florescent orange, this discovered recorder lived up to its name as a black box because fire had darkened it with ashes. 
 
 In addition, out of more than 2,000 DNA samples collected from the crash site, lab workers have isolated 150 DNA profiles, Robin told reporters. 
 
 "That does not mean we've identified" the crash's 150 victims, Robin said -- noting the recovered DNA still must be compared with DNA submitted by the families of those who died in the crash. 
 
 Authorities have also found 470 personal effects at the site, according to Robin. That number includes 40 cell phones, though all those were badly damaged. Robin cast doubt that any useful information could be retrieved from those phones, given their condition. 
 
 JUST WATCHED French reporter says he's seen Germanwings video Replay More Videos ... MUST WATCH French reporter says he's seen Germanwings video 03:06 
 
 That view is consistent with French officials' claims Wednesday insisting that two publications, German daily Bild and French Paris Match, were wrong to report that cell phone video showed the harrowing final seconds from on board the flight. 
 
 'Premeditated murder' claim 
 
 Noting he's made a criminal request to German authorities but is for now conducting his own investigation, the French prosecutor said he is tasked with an involuntary homicide investigation. 
 
 But Robin noted that Lubitz made voluntary actions -- such as guiding the plane toward the mountain and reducing its speed to prevent alarms from going off -- and was "alive and conscious" to the very end. 
 
 A European official government official with detailed knowledge of the investigation said that Lubitz's actions amount to "premeditated murder." 
 
 While cautioning that there are still many holes in understanding Lubitz's motivation, the disclosures about his Internet searches show that he planned to do what he was going to do, according to this official. 
 
 Source: Lubitz saw multiple doctors 
 
 It is becoming increasingly clear to investigators that Lubitz was "very afraid" he would lose his license to fly because of his medical issues, a law enforcement source with detailed knowledge of the investigation told CNN on Thursday. 
 
 It's already emerged that Lubitz had battled depression years before he took the controls of Flight 9525 and that he had concealed from his employer recent medical leave notes saying he was unfit for work. 
 
 But the law enforcement source said that after a severe depressive episode in 2009, Lubitz relapsed with severe depression and stress in late 2014. 
 
 In the weeks leading up to the crash, Lubitz was shopping doctors, seeing at least five, perhaps as many as six, the source said, as he kept going from one doctor to the next seeking help, including from a sleep specialist. He was prescribed powerful medication, though it's not clear he was taking it. ||||| Media playback is unsupported on your device Media caption Families have criticised Guenter Lubitz for speaking out on the crash's second anniversary 
 
 Families of victims of the Germanwings airline crash have criticised the father of the co-pilot for claiming on the second anniversary of the crash that his son was not responsible. 
 
 German prosecutors concluded in January that Andreas Lubitz, 27, was suicidal and flew the plane into the ground, killing all 150 people on board. 
 
 But Guenter Lubitz said on Friday his son was not depressed at the time. 
 
 Family members criticised the timing of his announcement. 
 
 His news conference fell on the same day that relatives are commemorating two years since the death of their loved ones. 
 
 Image copyright AFP Image caption Guenter Lubitz said he believed his son was innocent 
 
 Mr Lubitz's statement is the first public statement by a member of Lubitz's close family since the 2015 disaster. 
 
 He said: "Up to now, everyone has believed the theory of a co-pilot who was depressed for a long time, who deliberately crashed his plane into a mountain in a planned act. We are convinced this is false."

 Mr Lubitz, 63, said he has been working alongside a journalist, Tim van Beveren, who he called "an internationally recognised aerospace expert". 
 
 The two men plan to introduce a theory that a carbon monoxide leak in the cabin disabled Lubitz while the captain was locked out of the cockpit. 
 
 The cockpit voice recorder aboard the aircraft captured the sound of the captain attempting to break through the door with an axe as the aircraft plummeted to earth.

 Elmar Giemulla, a lawyer for several of the victims' families, said Mr Lubitz's actions were "irresponsible". 
 
 "I imagine that Mr Lubitz wants to promote a theory that would absolve his son of any responsibility," he told Germany's Rheinische Post newspaper. 
 
 Mr Lubitz told Die Zeit magazine: "Our son was a very responsible person. He had no reason to plan and carry out a suicide, and certainly not to take another 149 innocent people with him." 
 
 About 500 people are expected to travel to the French Alpine town of Digne-les-Bains for a church service to commemorate the victims.
– Investigators carrying out the grim task of recovering wreckage and human remains from the Germanwings crash say they have not found an intact body—or the flight data recorder. To aid the search, an access road is being built to the remote site in the French Alps, where forensic teams have so far recovered DNA belonging to 78 of the 150 people killed, the Guardian reports. Investigators say that so far, only the empty protective casing of the black box has been found. In other developments: Co-pilot Andreas Lubitz is believed to have deliberately crashed the plane, but with the failure to find the flight's second black box, some in the aviation world are saying it is too early to rule out other causes. Airbus chairman Tom Enders slammed TV coverage of the crash in an interview published yesterday, Deutsche Welle reports. "Sometimes people there speculate, fantasize, and lie with no basis in fact," he said, calling some of the reporting "outrageous nonsense" that was a "mockery of the victims." The cockpit voice recorder was recovered soon after the crash, and German newspaper Bild has published what it says is a leaked transcript. Capt. Patrick Sondenheimer (also spelled Sonderheimer or Sondheimer, depending on the source) can be heard pleading for Lubitz to let him back in the cabin, shouting, "Open the goddamn door!" as passengers scream minutes before impact, according to the transcript. A spokeswoman for France's accident investigation agency tells CNN that investigators are "dismayed" by the leak. Over the weekend, there were reports that Lubitz suffered from a psychomatic illness that may have been linked to a vision problem. German newspapers, including Bild, also reported that Lubitz's girlfriend, a teacher, was pregnant and the couple had planned to marry, according to the Independent. In Lubitz's hometown of Montabaur, the local Lutheran pastor tells the AP that despite mounting evidence that Lubitz caused the crash, he was still part of the community and the church is standing by his family. He says Lubitz's mother is a part-time organist for the church and he knew the co-pilot as a teenager. "This does not make sense. It is incomprehensible for me, for us, for everyone who knew her and the family," he says.
