The star basketball player whose secret was accidentally broadcast to the world. Did you hear that . Oh no the new apology as his team now heads to the elite eight. And we do say, good morning, america on this friday morning. Its been good to have t. J. And david with us here all week long. We have breaking new details about the plane crash. Investigators are sifts through the debris in the alps right now searching for that second black box. Robin, as you know the real search is happening at the copilots home in germany. Were learning more now about the man they say is responsible for that terrible tragedy that took 150 lives and have a team of correspondents standing by and abcs terry moran starts us off in the copilots hometown in germany. Terry, good morning. Reporter good morning, david. Here on the street where he lived, thats his mom and dads house right back there, people are wondering how their neighbor could have done this. Today german media is reporting that Andreas Lubitz suffered from Mental Health issues depression and it may have been so severe that it caused him to drop out of his Pilot Training several years ago. The search for clues expanding to lubitzs apartment in dusseldorf germany, overnight. Police seen removing boxes of evidence telling abc news they found something being analyzed but wouldnt comment on its significance. This as our picture of the 27 wrrld is becoming clearer. Born in germany, most of his time spent in his hometown with his parents. At the family home police lowering the shutters. Investigators carrying out bags of investigation and escorting someone past the cameras to a waiting car. The flag at the high school lubitz attended flying at halfstaff as the residents there remain in shock. Hes not the type of guy who would try to kill other people absolutely not. This man says. He was still a relatively inexperienced pilot with 630 hours of Flight Experience only 120 on the airbus a320. Lubitz worked as a Flight Attendant before that. He started his lufthansa training in 2008. Part took place near phoenix. An instructor telling abc news lubitz appeared normal. And the ceo for the Airline Claims lubitz passed Mental Health screening tests and was 100 fit to fly. But for the 149 others who flew with lubitz, all those innocents lost in this tragedy, that was clearly not true. Lufthansa officials are telling abc that they are aware of that mysterious break that lubitz took in his pilots training but they do not have access to the reasons why. They say they insist he passed his medical tests. Robin. Okay terry, thank you. Also learning more about those final moments on flight 9525. Investigators sifting through the wreckage looking for more clues. Abcs david kerley is here with those details. Good morning, david. Reporter it is about that allimportant question now, why . What motivated this young pilot to crash that jetliner with everybody on board and at this hour crews are back at work trying to find the answers. They have to rappel to the crash site searchers working in teams of two poking through the debris picking up possible clues digging to see if part of that other black box is buried but much of this debris will be left now that investigators say copilot Andreas Lubitz locked the captain out of the cabin. Once alone with that door locked flight tracking data shows he changes the autopilot sending it down towards the alps and the captain feels it descending heard on the recording knocking on the door no answer starts banging as if trying to break down the door silence from the copilot but on the recording, lubitz can be heard breathing normally. Seconds tick by the jet dropping more than 3,000 feet a minute closing in on the mountains in plain view of the passengers. They are heard on the recording too screaming in the final seconds before the crash. During those ten minutes of terror the captain couldnt get in but why . Its because of these twoinchstrong doors installed after 9 11. They automatically lock. There is a keypad outside. The pilot in the cockpit has 30 seconds to respond to override that code and keep the door locked in this case for another five minutes. That is one of the reasons that the u. S. Requires two in the cockpit at all times. If a pilot leaves hes replaced by a relief pilot or Flight Attendant. After this murderous evil act in the alps airlines are now adopting that twoperson policy including air canada and Norwegian Air and that search effort on the mountainside will probably be measured in days not weeks, robin. Weve seen human remains removed. One of the priorities still finding that second black box, the data recorder a priority robin. It certainly is. Well bring in abc news aviation consultant john nance in dallas. You heard here in the u. S. Two people are required to be in the cockpit at all times and understanding that other airlines now in other countries are now athe doing this position. Any safety mechanism that could be put in place to prevent Something Like this happening . Well i think, robin, that would have gone a long way if we had a second person in the cockpit. It will be difficult for a pilot trapped in the seat to attack a Flight Attendant or another pilot in there and subdue them so that is the quickest thing that we can do worldwide and really needs to be adopted worldwide. It does. I know you have been calling for that and other measures as well because the anxiety of so many people who travel i look at our studio audience and they travel here everyone does and just what can be done industrywide and worldwide to prevent this from happening . I think we need an immediate conversation with all the Worlds Airlines over what can be done and the philosophy to be followed. Its completely logical you would have this ability for a pilot to cancel the attempt of somebody to get in. But this of course was the fatal error in this particular accident. We probably need to reexamine that philosophy. Are you surprised how quickly we moved forward with this . I know some people in europe some european pilots were disturbed that the copilot so quickly was considered a culprit in all of this. I understand and that would probably be my reaction had i not known a piece of information here and that was the aircraft was broadcast adsb we know for a fact now because the aircraft told us that somebody reached up and turned that altitude selector from 38,000 feet to 100 feet. There was only one human in that cockpit. That was the copilot and thats definitive in that is the proof. All right. John thank you so much. David. All right, robin. We turn to that massive explosion in new york city at least 19 people injured when the blast ignited, a raging sevenalarm fire tearing through four buildings. One person still missing and abcs Ron Claiborne on the scene right here in new york city. Ron, good morning. Reporter hey, good morning to you, david. Now, 16 hours later, firefighters are still on the scene putting out hot spots. Three of those buildings collapsed, one suffering heavy damage from a blaze that was so hot, so intense at times that firefighters could not even get close to it.

A massive explosion explosion and do see the structure fall. Reporter the initial blast seen in this video obtained exclusively by wabc. Witnesses described a chaotic scene raging fire smoke so thick you couldnt see ten feet in front of you at times and survivors rushing from the flaming debris or jumping from windows to escape. All of a sudden i hear a huge boom. I look up and the building just went straight across. The injured, some of them critically were taken away on stretchers. But more than 200 firefighters battled the inferno, the thick acrid smoke visible for miles. At least one person still unaccounted for this morning. The family of 23yearold Nicholas Figueroa says he was at a restaurant on the bottom floor of one of the collapsed buildings and have not heard from him since. We call every hospital three or four times and want to see my brother home. Reporter con edison said utility crewed visited an hour before the explosion to check on work being done on gas lines. The cause is not officially determined but officials said preliminarily it appeared related to gas. The initial impact appears to have been caused by plumbing and gas work. Reporter almost exactly one year ago, a gas leak caused an explosion at this east harlem Apartment Building that killed eight people. And now this four fivestory buildings left in smoldering ruin and once again suspicion that a gas leak may have been to blame. And at latest report 19 people injured, four of them critically but, robin, searchers have not even been able to get inside that site yet to see if theres anyone else alive and possibly trapped there. Robin. Thank you. Now to the war on terror and an fbi undercover sting. Federal officials arresting a member of the u. S. Army National Guard and his cousin alleging the two were trying to join isis. Abcs Pierre Thomas is in washington with more on all that. Good morning pierre. Reporter good morning, robin. This appears to be the very first case of a current member of the u. S. Military seeking to fight with isis and theres an ugly twist. An alleged plot to attack right here at home. Army National Guardsman Hasan Edmonds was arrested at Midway Airport allegedly en route to join one of americas or shall enemies, isis the fbi says if that wasnt bad enough edmonds had hatched a plan with his cousin jonas to kill his fellow soldiers at a military base where he had trained outside of chicago. The alleged plan hasan was to give jonas his National Guard uniform and he would kill them in a massacre with a body count as high as 150. The likely target the joliet armory. It certainly speaks to the level of dedication and the lengths to which these individuals will go to advance isis mission and that means even carrying out an attack here inside the United States. Reporter but family members of the suspects believe the men were set up targeted for their religion. Thats ludicrous. They they arent terrorists. Thats just how i feel and i feel as if this is some form of prejudice because they choose to worship as muslims. Hasan edmonds is one of more than 20 people from inside the u. S. Caught within the last year allegedly trying to go overseas to join isis. David. Pierre thomas this morning, thanks. Now to the disgraced congressman who made headlines for his spending.
