The co-pilot of Germanwings A320 flight 4U9525 was alone inside the cockpit when the plane crashed killing 150 people, Marseille prosecutor Brice Robin has confirmed Thursday.
For this, prosecutors believe that the 28-year-old Andreas Lubitz hijacked, a German national hijacked Airbus A320 and flew into mountain killing 150 people in a mass murder suicide.
Earlier, a section of the media reported that one of the two pilots left the cockpit and could not get back in.
The captain, who has been confirmed as the one locked out when the plane crashed, had years of experience and more than 6,000 hours of flying time.
Lubitz had just 630 flying hours and joined Germanwings straight after training in September 2013.
The Airbus A320, operated by Germanwings, was travelling to Barcelona when it descended into the French Alps, killing the 144 passengers and six crew members on board.
