Piloting a plane to crash is not suicide, it’s mass murder. Lubitz was identified as a German citizen and Mr Robin said he was not known to terrorism links or extremist links, but the prosecutor said he was expecting more information from the German authorities. Marseille prosecutor Brice Robin added his religion was “unknown.”

(Reuters) – A young German co-pilot locked himself alone in the cockpit of a Germanwings airliner and flew it into a mountain with what appears to have been the intent to destroy it, a French prosecutor said on Thursday.

Investigators and grieving relatives were left struggling to explain what motivated Andreas Lubitz, 28, to kill all 150 people on board the Airbus A320, including himself, in Wednesday’s crash in the French Alps.

French and German officials said there was no indication the crash was a terrorist attack, but gave no alternative explanation for his motives.

Lubitz gained sole control of the aircraft after the captain left the cockpit. He refused to re-open the door and sent plane into its fatal descent, Marseille prosecutor Brice Robin said.

He did this “for a reason we cannot fathom right now but which looks like intent to destroy this aircraft,” Robin told a news conference in Marseille broadcast live on national TV.

Describing the final 10 minutes of the passengers on board as the plane hurtled towards a mountain range, Robin said sound recordings from one of its black boxes suggested most of them would not have been aware of their fate until the very end.

“Only towards the end do you hear screams,” he said. “And bear in mind that death would have been instantaneous … the aircraft was literally smashed to bits.”

The CEO of Lufthansa, parent company of Germanwings, said its air crew were picked carefully and subjected to psychological vetting.

“No matter your safety regulations, no matter how high you set the bar, and we have incredibly high standards, there is no way to rule out such an event,” CEO Carsten Spohr said.

The world’s attention will now focus on the motivations of Lubitz, a German national who joined the budget carrier in September 2013 and had just 630 hours of flying time – compared with the 6,000 hours of the flight captain, named in German media only as “Patrick S.” in accordance with usual practice.

Robin said there were no grounds to suspect that Lubitz was carrying out a terrorist attack. “Suicide” was also the wrong word to describe actions which killed so many other people, the prosecutor added: “I don’t necessarily call it suicide when you have responsibility for 100 or so lives.”

Police set up guard outside Lubitz’s house in Montabaur, Germany. Acquaintances in the town said they were stunned, describing him as an affable young man who gave no indication he was harbouring any harmful intent.

“I’m just speechless. I don’t have any explanation for this. Knowing Andreas, this is just inconceivable for me,” said Peter Ruecker, a long-time member of the local flight club where Lubitz received his flying license years ago.

“He was a lot of fun, even though he was perhaps sometimes a bit quiet. He was just another boy like so many others here.”

Robin said the conversation between the two pilots before the captain left the cockpit started normally but that Lubitz’s replies became “laconic” as they started readying what would have been the normal descent to the airport of Duesseldorf.

“His responses become very brief. There is no proper exchange as such,” he said. It was not clear why the captain had left the cockpit but it was probably to use the toilet, he said.

Robin said the family of the co-pilot had arrived in France for a tribute alongside other those of the victims but was being kept apart from the others.

“SMASH THE DOOR DOWN”

The New York Times cited an unnamed investigator as saying the recording shed insight into the moment when it dawned on the captain that he had been shut out of the cockpit.

“The guy outside is knocking lightly on the door and there is no answer,” it quoted an investigator described as a senior French military official as saying. “And then he hits the door stronger and no answer. There is never an answer.”

“You can hear he is trying to smash the door down,” the investigator added.

Investigators were still searching for the second of the two black boxes on Thursday in the ravine where the plane crashed, 100 km (65 miles) from Nice, which would contain data from the plane’s instruments.

France’s BEA air investigation bureau had said on Wednesday it expected the first basic analysis of the voice recordings in days.

Pilots may temporarily leave the cockpit at certain times and in certain circumstances, such as while the aircraft is cruising, according to German aviation law.

Cockpit doors can be opened from the outside with a code, in line with regulations introduced after the Sept. 11, 2001 attacks in the United States, but the code can be overridden from inside the cockpit. Lufthansa’s CEO said that either the pilot had entered the code incorrectly, or the co-pilot inside had overridden it.

The BEA on Wednesday already ruled out a mid-air explosion and said the scenario did not look like a depressurisation.

Germanwings said 72 Germans were killed in the first major air passenger disaster on French soil since the 2000 Concorde accident just outside Paris. Madrid revised down on Thursday the number of Spanish victims to 50 from 51 previously.

As well as Germans and Spaniards, victims included three Americans, a Moroccan and citizens of Britain, Argentina, Australia, Belgium, Colombia, Denmark, Israel, Japan, Mexico, Iran and the Netherlands, officials said. However, DNA checks to identify them could take weeks, the French government said.

The families of victims were being flown to Marseille on Thursday before being taken up to the zone close to the crash site. Chapels had been prepared for them with a view of the mountain where their loved ones died.

From Dailymail:

HOW ACCESS TO THE COCKPIT DOOR CAN BE DISABLED FROM THE INSIDE

Access to the cockpit door on the Germanwings Airbus A320 (like the one above) can be disabled from inside the flight deck, raising speculation that one of the pilots deliberately locked the other out The Airbus A320 is fitted with a locking mechanism to prevent unauthorised access to the flight deck while the aircraft is in flight. The safety systems were improved in the aftermath of the 9/11 terror attacks where hijackers were able to gain access to the cockpit and take over the aircraft. In normal flight, the door to the flight is closed and locked. Cabin crew can use a code and gain access to the flight deck. Entry is controlled by the flight crew, in case of a possible hijack attempt. The Cockpit Door Locking System (CDLS) according to the flight manual ‘provides a means of electrically locking and unlocking the cockpit door’. The CDLS is located in the central pedestal between both pilots and has a toggle switch which controls the door. They also have a CCTV camera so they can see who is seeking access, and if they are under any form of duress. Pilots can restrict access to the flight deck although cabin crew can gain entry in an emergency. However, this emergency access can be over-ridden by the pilot for between five to 20 minutes. The limited time to keep the door closed is itself a safety feature, in case the flight crew become incapacitated – known in the industry as ‘incap’. After the predeterminted time, the keypad on the outside of the cockpit door will become operational again, unless the pilot actively restricts access again. Also the cockpit door has several other safety features in case of a sudden decompression which will cause the door to open. According to the flight manual there are ‘routine’ and ‘emergency’ access requests. ‘The toggle switch enables the flight crew to lock or unlock the cockpit door, following an access request, thereby allowing or denying the entry to the cockpit.’

The Cockpit Door Locking System, pictured, has several safety features to prevent unauthorised access to the cabin, however, this can be overridden if the flight crew become incapacitated for any reason

The flight manual states that the control unit is responsible for:

Locking or unlocking the door latches, upon flight crew action

Unlocking the door i, in case of cockpit decompression (the door then opens towards the cockpit under differential pressure)

Indicating system failures of electrical latches and pressure sensors

Activating the access request buzzer and turning on the keypad LEDs

On the Airbus A320, there are three settings:

Unlock: This position is used to enable the cabin crew member to open the door. The switch must be pulled and maintained in the unlocked position until the door is pushed open.

Normal: All latches are locked, and EMERGENCY access is possible for the cabin crew

Lock: Once the button has been moved to this position, the door is locked; emergency access, the buzzer, and the keypad are inhibited for a preselected time (5 to 20 min)
