Germanwings co-pilot Andreas Lubitz, aged 27, who crashed an Airbus 320 into the French Alps in March killing himself and another 149 people had gone on a trial run on the previous flight.  Sources from France’s BEA crash investigation agency state that the report being released on Wednesday includes information about the pilot’s behavior in the previous Barcelona-Dusseldorf flight where he had once again locked the captain out of the cockpit and veered the plane into early descent though there had been no aeronautical justification for this.

Lubitz is believed to have pinned the plane to the mountainside as a result of severe depression he had been suffering from. Police found that he had used his computer to conduct internet research into the ways of committing suicide.
