A mother of a schoolmate of co-pilot Andreas Lubitz told the Frankfurter Allgemeine Zeitung he had told her daughter that he had taken a break from his pilot training because he was suffering from depression.
"Apparently he had a burnout, he was in depression," the woman, whom the paper did not name.
She said her daughter had seen him again just before Christmas and that he had appeared normal. The mother of his schoolmate said he was a "lovely boy". "He had a good family background," she told the paper.
