DHAKA: The co-pilot of the Germanwings airliner that crashed in the French Alps killing all 150 people aboard appears to have brought the A320 Airbus down deliberately.

The Marseille prosecutor said on Thursday, reports The Jerusalem Post.

German Andreas Lubitz, 28, left in sole control of the Airbus A320 after the captain left the cockpit, refused to re-open the door and operated a control that sent the plane into its final, fatal descent, the prosecutor told a news conference.

The French prosecutor said Lubitz was not known as a terrorist and there were no grounds to consider the crash as a terrorist incident. Recordings suggested passengers' screams began just before the final impact, he said.

Earlier, a German state prosecutor had said that just one of the two pilots of the Germanwings airliner was in the cockpit at the time it went down.

The statements came after the New York Times reported that ‘black box’" recordings showed one of the pilots had left the cockpit and could not get back in before the plane crashed.

‘One was in the cockpit and the other wasn’t,’ Christoph Kumpa at the prosecutors’ office in Dusseldorf told the media by telephone, adding that the information came from investigators in France.
