The 27-year-old's parents’ neighbours in the affluent suburb on the edge of Montabaur all spoke of a polite, if not particularly gregarious, man. Johannes Rossbach, 23, who lives two doors away from Lubitz, said he would regularly see the pilot jogging through the neighbourhood's quiet streets.Mr Rossbach said: "He was very polite. He would always say hello and goodbye. There certainly seemed nothing out of the ordinary about him."
He added: "I didn't realise he was a pilot until I heard it yesterday. And today's news is absolutely shocking. I can't believe someone like that would kill 149 other people. It's something that absolutely needs investigating and proving before we can believe it."
