some clues. day five and the mountain still holds secrets the investigators are hunting for. but they're focused too on the secrets of the man who caused all this. co-pilot andreas lubitz hid medical problems from the airline he worked for, but was more candid with a flight attendant who said she was his former girlfriend. in an interview with germany's best-selling tabloid newspaper. she claimed lubitz said last year one day i'm going to do something that will change the whole system and then everyone will know my name. she'd flown with lubitz for several months and said he had health problems and felt pressured by work. nbc news can't confirm her allegations, but investigators are now focusing on his mental state and medical records. after finding torn up sick notes at his apartment declaring him unfit to work on the day of the crash. today, more than 30 investigators were flown to the crash site to search for the

missing flight recorder and for bodies. the helicopters are coming and going here every few minutes. the cause of this crash may be known, but the search goes on. it is relentless. and it is hard. so far they've brought back more than 600 body parts. >> the first priorities is identification of the bodyies bodies. the fact there is 150 people die there so that's why it's hard. >> reporter: one pilot has seen more than most. >> we were the first to find the crash. >> reporter: the first pilot in is still shocked. >> a plane crash on the ground and you can't see anything. it's a little millions of pieces all over the floor. >> reporter: the family of the plane's pilot who tried to smash his way back into the locked cockpit, got as close as they could today. like the other bereaved gathering beneath the mountain where their loved ones still lie, lost in
