The chilling words that Germanwings co-pilot Andreas Lubitz spoke to his girlfriend last year

An ex-girlfriend of the Germanwings co-pilot blamed for deliberately crashing a passenger plane in the French Alps - killing all other 149 people on board - has claimed he had vowed to "do something" that he would be remembered for.

The woman, identified only as Mary W, told Bild newspaper that Andreas Lubitz had told her:

One day I will do something that will change the whole system, and then all will know my name and remember it.

She added: "I never knew what he meant, but now it makes sense."

Mary, a member of an airline cabin crew, said Lubitz, 27, had suffered from nightmares.

"At night, he woke up and screamed: 'We're going down!', because he had nightmares," she said. "He knew how to hide from other people what was really going on inside."

It has emerged that Lubitz concealed a sick-note declaring himself unfit to work on the day he is thought to have crashed the Airbus A320, which was travelling from Barcelona to Dusseldorf, on Wednesday.
