Did suicidal pilot crash Germanwings jet?

It is almost as if Stephen King had written the script. In the past six years a series of commercial airline crashes has raised questions about whether crazy computers had taken over aviation.
Five crashes have occurred that were the result of unexplained circumstances.
In the latest, the almost immediate discovery of the wreckage and black box made it appear likely investigators would quickly be able to explain why 150 people had died on a flight from Barcelona to Dusseldorf.
French prosecutor Brice Robin on Thursday said information from the flight recording equipment indicates co-pilot Andreas Lubitz wanted to “destroy the plane,” according to the BBC. Lubitz maneuvered the plane into a descent and crashed it into the mountains.
The pilot could be heard pounding on the cockpit door and the passengers screaming as the plane hit the mountainside.
Media reports were quick to report that the Germanwings Airbus subsidiary had issued a distress call before crashing into the Alps on Tuesday.
There was no distress call, merely air traffic controllers designating that the plane had left its route.
The New York Times later reported one of the flight data recorders indicated one of the pilots had left the cockpit and had been locked out before the plane began descending into the mountains.
He could be heard trying to force his way back into the cockpit. It wasn’t clear whether it was the pilot or co-pilot.
On Wednesday, the Times reported: “The guy outside is knocking lightly on the door, and there is no answer. And then he hits the door stronger, and no answer. There is never an answer.” Then, the source said, “You can hear he is trying to smash the door down.”
There was no weather condition that would have led to the plane descending, and it did not seek to be looking for a place to land.
“We don’t know yet the reason why one of the guys went out. But what is sure is that at the very end of the flight, the other pilot is alone and does not open the door,” the investigator.
It is possible that after one pilot left the cockpit that the other had some kind of medical emergency. It was not clear whether the pilot who had left the cockpit should have been able to get back inside.
