Germanwings co-pilot Andreas Lubitz told his girlfriend that "one day I will do something that will change the whole system, and then all will know my name and remember it," a German newspaper reported Saturday.
In another development in a bizarre story, police revealed evidence seized at his home suggests he suffered from a "serious psychosomatic illness." Police reportedly found drugs used to treat mental illness at his apartment in Dusseldorf.
The German newspaper Welt interviewed Libitz's former girlfriend, a 26-year-old stewardess for Germanwings, who said he was a troubled man who sometimes awoke from nightmares screaming "We're going down!"
The woman, who said she Lubitz for five months, said he woulds change rapidly from someone who was needy into an angry man.
She told another newspaper, Bild: "We spoke a lot about work and then he became another person. He became agitated about the circumstances in which he had to work, too little money, anxiety about his contract and too much pressure."
"During conversations he'd suddenly throw a tantrum and scream at me," she said. "I was afraid. He even once locked me in the bathroom for a long time."
His behavior so troubled her that she ended the relationship.
"When I heard about the crash, there was just a tape playing in my head of what he said, 'One day I will do something that will change the system and everyone will then know my name and remember me.'
"I did not know what he meant by that at the time, but now it’s clear." She added: 'The torn up sick notes make sense now to me and were a clear sign that he did not want to admit that his big dream of flying as a captain was over."
As for the "serious psychosomatic illness," a source in the police investigation team told Welt: "This is clear from personal notes stored and collected by the pilot."
