調查德國日耳曼之翼航空公司(Germanwings)墜機的法國檢察官表示，班機上單獨留在駕駛艙的副機師，在飛機墜毀於法國南部山區之前，依然是有清醒的。
檢察官指出，這名副機師顯然想要摧毀這架飛機。
根據消息人士，這架班機墜毀之前，機師被鎖在駕駛艙之外，不得其門而入。
消息人士說，現場尋獲的座艙語音記錄器顯示，艙內1個座位被推開，艙門打開、關上。然後聽到敲門的聲音。「從這個時間到飛機墜毀前，艙內沒再聽到任何對話」。
消息人士又說，座艙語音記錄器可以聽到飛機在墜毀前接近地面的警報聲大作。失事客機沒發出求救訊號，副機師對亟欲聯絡的地面控制中心，沒有回應。
The co-pilot of the Germanwings plane that crashed into the French Alps on Tuesday appeared to want to “destroy the plane”, French officials said.
Marseille prosecutor Brice Robin, citing information from the “black box” voice recorder, said the co-pilot was alone in the cockpit.
He intentionally started a descent while the pilot was locked out.
Mr Robin said there was “absolute silence in the cockpit” as the pilot fought to re-enter it.
Air traffic controllers made repeated attempts to contact the aircraft, but to no avail, he said.
Passengers could be heard screaming just before the crash, he added.
The co-pilot, now named as Andreas Lubitz, 28, was alive until the final impact, the prosecutor said.
The Airbus 320 from Barcelona to Duesseldorf hit a mountain, killing all 144 passengers and six crew, after an eight-minute descent.
“We hear the pilot ask the co-pilot to take control of the plane and we hear at the same time the sound of a seat moving backwards and the sound of a door closing,” Mr Robin told reporters.
He said the pilot had probably gone to the toilet.
“At that moment, the co-pilot is controlling the plane by himself. While he is alone, the co-pilot presses the buttons of the flight monitoring system to put into action the descent of the aeroplane.
“This action on the altitude controls can only be deliberate.”
He added: “The most plausible interpretation is that the co-pilot through a voluntary act had refused to open the cabin door to let the captain in. He pushed the button to trigger the aircraft to lose altitude. He operated this button for a reason we don’t know yet, but it appears that the reason was to destroy this plane.”
He said the co-pilot was “not known by us” to have any links to extremism or terrorism.
But he said German authorities were expected to give further information on his background and private life later.
Meanwhile. relatives and friends of the victims are due to visit the area of the crash.
Lufthansa, which owns Germanwings, arranged two special flights for families and friends on Thursday – one from Barcelona and one from Duesseldorf – to Marseille, and both groups will travel on by road. Separately, some relatives who did not want to fly are travelling by bus from Barcelona.
