PARIS: The Germanwings co-pilot who deliberately ploughed a plane into the French Alps saw 41 doctors in five years, seven of them in the month before the crash that left 150 dead, a prosecutor said Friday. Andreas Lubitz, "concerned about his health and fearing a loss of his sight" suffered from severe depression and "psychosis", said Brice Robin, prosecutor for the southern city of Marseille, after meeting families of the victims.
