Germanwings crash: Co-pilot Lubitz 'practised rapid descent'
The co-pilot of the Germanwings plane that crashed in the French Alps in March may have practised a rapid descent on a previous flight, a report by French investigators has said, the BBC reported.
The report said Andreas Lubitz repeatedly set the plane for an unauthorised descent earlier that day.
Lubitz is suspected of deliberately crashing the Airbus 320, killing all 150 people on board.
He had locked the flight captain out of the cockpit.
The plane had been flying from Barcelona to Duesseldorf on 24 March.
The alteration of the settings occurred on the plane's outbound flight from Duesseldorf to Barcelona on the same day, the report by accident investigation agency BEA said.
