After prosecutors made it clear that the co-pilot, Andrews Lubitz had decisively crashed the Germanwings plane of Lufthansa two days ago, now a criminal inquiry is being focused on Lubitz and the reasons for him to commit a suicide.

Andrews’ act left everyone right from the top executive of the Lufthansa speechless. The 27-year old flying enthusiast is from the German town of Montabaur but had an apartment in Dusseldorf.

Andrews joined Germanwings less than two years ago and has an enthusiast of flying.

Robin, the French prosecutor, said the voice recorder showed details of the final 30 minutes of the flight. "During the first 20 minutes, the pilots talk normally," he said. "There is nothing abnormal happening."

He even denied the terror links to the incident.

Members of a flight crew would typically use a fail-safe code to open the door if someone in the cockpit could not or would not let them in. The pilot would have known the code, an official said, but it was unclear whether he had used it. Even if he did, the co-pilot could have activated a switch that prevented the door from opening for five minutes, or found some other way to block the door, he added.

There is no chance the pilot forgot the code, he said.
