the findings bolt ss bolster the belief it was premeditated. investigators interviewed a pilot who flew with lubitz the day before the crash. he didn t suspect anything was wrong. it was probably planned on some particular flight. i don t believe that it was necessarily this flight. it sounds to me like there was some urging with reference to the captain s lavatory usage on this one. reporter: inside lubitz s apartment, a law enforcement says investigators also found personal memos with only a couple of words involving stress and his pilot license. that source says lubitz was prescribed medication for depression in the months leading ging up to the crash. lubitz told one of his doctors he was afraid his medical issues could jeopardize his ability to fly. that remains a main working theory, that he was afraid to lose his pilot license. we know that from a source that investigators have been talking to his doctors, looking at
investigators belief the crash was premeditated. investigators have also interviewed a pilot who flew with him the day before the crash. he said he didn t suspect anything was wrong. it was probably planned on some particular flight. i don t believe that it was necessarily this flight. it sounds to me like there was some urging with reference to the captain s lavatory usage on this one. reporter: inside lubitz s apartment, memos were found regarding stress and his pilot s license. he was prescribed medication for depression in the months leading up to the crash and a source says he told at least one of his doctor he was afraid his medical issues could jeopardize his ability to fly. law enforcement source says that investigators have been looking through the notes from the doctors, talking with the doctors they haven t found any
those doctors talking to each other. you know, the point is, you re supposed to self-report. if you self-report something along the lines of what we re hearing here, you re out of a job, essentially. so you could see that the inherent conflict of interest here in this system. let me ask you this, this is something that s a renewed debate here. we have seen that pilot suicides have occurred before, but rarely. now we re seeing many airlines change their cockpit rules, specifically here in europe to have two people in the cockpit at all times. do you think this will make flying safer? well, it can t hurt. and it doesn t cost anything. and there s a separate issue here as well. you have this very young pilot alone at the controls. it s probably a good idea to have somebody with him in there, just in case something happens, if nothing else to notify the captain in the lavatory. so i think for a lot of good reasons, it s a good idea. you don t want the individual

requires two people to remain on the flight deck at all times. if a pilot leaves to use the lavatory, a flight attendant normally remains in the cockpit. if the flying pilot then has a medical problem or anything like that, you have somebody else in the flight deck that can assist them but can also get the door open for the other pilot to return. reporter: most of the nations and airlines including lufthansa did not have the two-person rule. lufthansa joined a growing number of airlines who are adopting the rule immediately, including air berlin air canada. flights ending a mass murder are rare but they have happened. the ntsb concluded suicidal pilots crashed egypt air flight 980 and silk air 195 killing everyone onboard and it s among the leading theories of the disappearance of melee shah flight 370 last year. noticing a pilot has a psychological issue can be difficult. once hired their yearly
