"We can only speculate on the motives": Lufthansa head

"We can only speculate on the motives," said Lufthansa chief executive Carsten Spohr on Thursday at a press conference after the statements in Marseille that the co-pilot of the crashed Germanwings flight 4U9525 had deliberately brought the plane to crash.

However, there is no indication that one would suspect co-pilot's terrorist intentions, said Spohr.

According to Spohr, there are regular aeronautical examinations and once a year a medical check after pilot finished training in an aviation school. But "there is no regular psychological checks, " said Spohr.

He also noted that the event is "an incredibly tragic individual case", adding that the company has "firm confidence" in the selecting and training procedure as well as the work of its pilots.

"No matter what security measures are invested in the company, such individual cases can not be ruled out," said Spohr in Cologne. Enditem
