Killer pilot Andreas Lubitz told his ex-girlfriend he was planning an act so heinous his name would be remembered for ever, it was sensationally claimed last night.
Lubitz was a tormented, erratic man who was a master of hiding his darkest thoughts and would wake up from nightmares screaming were going down, his former partner said.
She revealed to a German newspaper how Lubitz ominously told her last year: One day I will do something that will change the whole system, and then all will know my name and remember it.
When she heard about the crash of Germanwings Flight 4U9525 on Tuesday, she remembered Lubitzs menacing prophecy. I never knew what he meant, but now it makes sense, she told Bild.
His personal problems and erratic behaviour was so severe that she was frightened and decided to leave him.
She added: 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 its clear.
Police will want to interview the unnamed former girlfriend in detail about the pilots state of mind. The couple had been together for seven years and lived in a smart flat on the outskirts of Dusseldorf. One report claimed they were engaged and planned to marry next year.
